The 4LS sensor is a quad linear line scan sensor for colour imaging applications with two pixels types. The data from the 4 lines is provided at the same time for all the outputs. The sensor features a low noise pixel with true CDS and global shutter for interleaved readout during integration. Each line has its own column parallel ADC, which can be configured individually for each of the 4 lines to equalize colour miss match or enable wide dynamic range. The readout is performed over LVDS bit serial taps which can be multiplexed to reduce output tap count. For scanning applications, for instance, the sensor provides up to 160kHz line rate in full resolution and can increase the line rate when using partial readout mode (ROI). The Black and White version of the sensor is ideal for 4:1 digital TDI. The Colour version, which offers Red, Green, Blue, and Clear channels, allows to combine the colour information with NIR information, revealing otherwise hidden details.
