2048-pixel CCD Linear Image Sensor (B/W) with Shutter Function

Description

The ILX703A is a reduction type CCD linear sensor designed for facsimile, image scanner and OCR use. This sensor reads B4 size documents at a density of 200 DPI (Dot Per Inch). Featuring a shutter function, correspondences with the sensitivity correction, etc, is possible. A built-in timing generator and clockdrivers ensure direct drive at 5V logic for easy use.

Notes)

1) For the sensitivity test light is applied with a uniform intensity of illumination.

2) W lamp (2854K)

3) Light source: LED λ = 570nm

4) Light source: LED λ = 660nm

5) PRNU is defined as indicated below. Ray incidence conditions are the same as for Note 1.

PRNU = × 100 [%]

(VMAX – VMIN)/2

VAVE

The maximum output is set to VMAX, the minimum output to VMIN and the average output to VAVE.

6) Integration time is 10ms.

7) VOUT = 500mV

8) DR = VSAT/VDRK When optical accumulated time is shorter, the dynamic range gets wider because dark voitage is in proportion to optical accumulated time.

9) SE = VSAT/R1

11) To stipulate the lag during shutter operation, use the formula below. Place the output voltage average value during shutter operation at VSHUT and the output voltage average value when the shutter is not in operation at VAVE. (Refer to Figure 7.)

SHUT = × 100 [%]

Please note that the shutter pulse at this time accord with Figure 6.
