Cohu Electronics

5930 Series Thermal Camera User's Manual

Product Description

The Cohu 5930 series is a long wavelength (LWIR) Infrared microbolometer based camera system. The
embeddable electronics provides the foundation for the processing and signal generation for the camera.
Below is a description of all the different aspects that make up the complete camera assembly.

1.1 FPA Description

The FPA used in the 5930 is an uncooled 320 x 240 matrix or "staring" array of microbolometer
detectors (51um square), sensitive in the 8.0-14.0 micron range. The FPA is enclosed in an all­metal evacuated dewar package, and is thermally stabilized by the electronics using a built in TE
cooler. The FPA incorporates internal thermal reference detectors that provide compensation for
thermal drift and noise.

1.2 Hardware Description

The camera electronics are comprised of four major circuit boards as described below.

1.2.1 FPA Support PCB

The FPA support PCB provides all the interface signals required to control the FPA. The FPA
Support PCB supports all the FPA functions as listed in Table 1.
