CMOS linear image sensor


40 MHz operation, digital output



The S15611 is a CMOS linear image sensor that has achieved a readout speed of 40 MHz max. and a line rate of 34 kHz max. The image sensor has a timing generator, bias generator, 12-bit A/D converter, and is easy to handle because of its digital I/O.


-Pixel size: 7 × 200 μm
-Number of pixels: 1024
-Effective photosensitive area length: 7.168 mm
-High-speed readout: 40 MHz max.
-Simultaneous integration of all pixels
- With variable integration time function
 (electronic shutter function)
-Single 3.3 V supply voltage operation
-SPI communication function
 (partial readout, offset adjustment)
-Built-in 12-bit A/D converter


Application example (SD-OCT)


Light from a broadband wavelength light source is shone on the sample, the interference light spectrally dispersed, then detected by a linear image sensor. An image in the depth direction of the sample is acquired by Fourier transforming the obtained wavelength information.




Linear encoder

This linear image sensor with rectangular pixels, high line rate, and a global shutter function is appropriate for absolute track reading of linear encoders.
