General Description

4LS is a family of high-speed line-scan sensors featuring four lines of pixels, spaced with one pixel

period line gap. The sensors are provided in Monochrome (B&W) version, allowing amongst other

applications 4-To-1 digital TDI or with Red, Green, Blue and Monochrome lines for high quality color

line scanning with extended spectral range. Each of the four lines of the sensor has individual gain

settings and can be triggered for exposure and reset independently. Moreover, all four lines can be

read out simultaneously over bit serial LVDS output taps.

The sensor features a low noise pixel with true CDS and global shutter allowing fully pipelined readout

and integration. To enhance dynamic range, multiple nondestructive readouts are possible.

An Invar based sensor chip on board is provided, which features all necessary external decoupling

elements and provides mechanical alignment features for high precision self-aligned mounting of the

sensors to its optics. Furthermore, the Invar core avoids thermal stress induced bending of the

sensors with more important line length.
