SECTION I. SYSTEM OVERVIEW

1-1. SCOPE OF MANUAL
This instruction bulletin covers installation, setup, operation, troubleshooting, and maintenance of the AOTF-NIR™ Analyzer, manufactured by Rosemount Analytical, Incorporated. The trouble­shooting and service procedures in this manual are limited to those that can be performed by most equipment operators.
1-2. FUNCTIONAL EQUIPMENT DESCRIPTION
When properly configured, the AOTF-NIR Analyzer can detect and measure the concentration of sample components that absorb light in the near-infrared spectrum.
Functional components of the analyzer (Figure 1-1) include a light source, an optical sampling chamber (sample cell), an acousto-optic tunable filter and detector (optics pedestal) and a microprocessor. The light source is housed in a source module, while the optics pedestal, microprocessor and related electron­ics are housed in an analyzer module. In normal use, an output flow from the sample process being moni­tored is routed through the sample cell.
a. Light Source and Sample Cell. The light
source sends a beam of light through a condens­ing lens and a fiber optic cable to the sample cell. On the input side of the sample cell, a collimat­ing lens aligns the light beam to project parallel rays across the cell. As process sample flows through the sample cell, the collimated light rays pass through the sample.
Depending on the chemical content of the proc­ess sample, specific wavelengths of near-infrared light are absorbed. For absorbed wavelengths, concentrations of light-absorbing components greatly reduce the intensity of light rays passing through the sample.
Unabsorbed light passes through the sample and strikes a second condensing lens. This lens focuses the light onto another fiber optic cable. This cable transmits the beam to the optics pedestal.
b. Optics Pedestal. At the optics pedestal, the con-
densed light passes through another collimator lens. This lens projects the light’s rays onto the face of an Acousto-Optic Tunable Filter (AOTF).
The AOTF is an adjustable light filter. The filter includes an acoustic transducer bonded to a Tellurium Dioxide (TeO
) crystal.
2
The RF transducer is driven by high energy RF frequencies from an RF amplifier. The trans­ducer generates acoustic waves corresponding to the frequency of the input signal. These acoustic waves change the refractive index of the crystal, changing its light filtering capability. Therefore, by controlling the output of the RF amplifier, the AOTF-NIR Analyzer tunes the AOTF to pass discrete wavelengths of light.
For each scan of the process sample, the analyzer sends a series of different frequencies to the AOTF crystal. Each frequency allows a different bandwidth of light to pass. The analyzer corre­lates the bandwidth of the passing light with the acoustic frequency. The importance of this will be seen later.
The condensing lens collects selected wave­lengths from the AOTF crystal. The condensing lens focuses the rays onto a photo detector. The incident light causes the detector to generate an electrical (millivolt) output. The amplitude of the output signal is directly related to the intensity of the light striking the detector. These millivolt output signals are then amplified and sent to the analyzer’s DSP.
c. Signal Processing and Conditioning Circuits.
Signals to and from the optics pedestal are proc­essed and conditioned in the detector pre-amp, DSP, and RF Synthesizer Modulator, and Ampli­fier circuits. These circuits are described in Sec­tion III of this manual.
d. Microprocessor. The microprocessor stores data
points as light intensity with respect to the corre­sponding drive (RF) frequency. Each discrete RF frequency corresponds to a discrete IR (infra­red) wavelength. The operator can create a model by taking scans of different known amounts of the substance(s) of interest. With this model in memory, the microprocessor can then take the intensity vs. frequency data it receives from the DSP and calculate the current concen­tration of the substance(s). Depending on the configuration setup, it can display this output on the GUI display, the analog output, or directly to the drive of the host PC.

The tungsten halogen lamp (Figure 2-2) produces an intense, but dispersed light beam with energy band­widths in the visible-NIR spectrum. The transfer op­tics (lens assembly) collects the dispersed light and focuses an intense beam onto the end of the fiber op­tic cable. The fiber optic cable transports the light en­ergy intact along the full length of the cable.

SECTION III. ANALYZER MODULE

3-1. GENERAL DESCRIPTION
The analyzer module (Figure 3-1) contains three main components: the RF amplifier, the optical as­sembly, and the electronics package. In addition, the analyzer module includes a General User Interface (GUI), high voltage power supply, low voltage power supply, power distribution and output termination board, and thermoelectric cooler. Each of these com­ponents is described in the following paragraphs.
3-2. RF AMPLIFIER
The RF amplifier receives a series of frequency sig­nals from the electronics package. The amplifier
increases the amplitude of the frequency signals and
sends them to the Acousto-Optic Tunable Filter (AOTF) on the optical assembly.
3-3. OPTICS PEDESTAL
The optics pedestal includes a collimator assembly, an acousto-optic tunable filter, a convex condensing lens, and a detector.
a. Collimator Assembly. Incoming light is emitted
from the fiber optic cable in a dispersed pattern. The collimator collects and aligns the light and projects parallel light rays onto the AOTF crystal.

b. Acousto-Optic Tunable Filter (AOTF). The
AOTF assembly is made up of an acoustic (piezo-electric) transducer and a tunable filter made of Tellurium Dioxide (TeO
) crystal. The
2
AOTF assembly controls the passage of discrete wavelengths of near-infrared light.
7
By changing the frequency received from the RF amplifier, the spectral grating of the filter is ad­justed. At any given acoustic frequency, the filter will pass a discrete wavelength of light. The analyzer sends a series of different frequencies to the AOTF crystal in order to scan all discrete wavelengths within a specified bandwidth.
c. Condensing Lens. The light passing through
the AOTF crystal is collected by a convex con­densing lens. The condensing lens causes the light to converge and focus on the PbS detector assembly. This allows the full intensity of the passing light to be detected and measured.
d. PbS Detector Assembly. The PbS detector as-
sembly includes a lead sulfide (PbS) photo de­tector and a preamplifier board. Both are mounted on top of the optical assembly.
The photo detector converts light energy into electrical energy. When a condensed beam of light strikes the photodiode, the photodiode emits a small voltage. The voltage level of the signal is directly related to the intensity (energy) of the light beam. The electrical signal (millivolts) is sent directly to the preamplifier. The preamplifier conditions the electrical signal for processing in the electronics package.

the analyzer’s microprocessor. The microproces­sor is programmed to output specific RF scan signals.

3-4. ELECTRONICS PACKAGE (CARD RACK)

The electronics package (card rack) (Figure 3-2) contains six printed circuit boards connected to a nine card backplane.
The printed circuit boards used in the card rack in­clude: the frequency synthesizer card, the Digital Signal Processing (DSP) card, the microprocessor (CPU) card, the memory card, the analog output card, and the Input/Output (I/O) card. The function of each card is described in the following paragraphs.
a. Frequency Synthesizer Card. The frequency
synthesizer card generates RF signals at specific frequencies and amplitudes. The frequencies and amplitudes of the RF signals are controlled by
b. Digital Signal Processing (DSP) Card. The
DSP has two functions in the AOTF-NIR. The first is to generate a 1000 Hz square wave that is sent to the frequency synthesizer board. This modulates the synthesizer board’s RF output by turning on and off the RF output at 1000 Hz, like a chopper motor does with light.
The second role is to convert analog signals from the PbS detector board into digital data. It syn­chronizes the sampling of the detector signal to coincide with the square wave, rejecting any ran­dom noise and boosting the signal to noise ratio.
The digital data is sent to the microprocessor board as raw data.
