The LS4k is a high speed CMOS System on Chip (SoC) line scan image sensor optimized for applications requiring short exposure times and high accuracy line rates. It incorporates on chip two pixel arrays consisting of 2 rows with 4,096 7μm pitch pixels and 4 rows with 2,048 14μm pitch pixels respectively, a high accuracy (12-bit) high speed (84MHz) analog-to-digital conversion (ADC), and sophisticated on chip optical calibration for PRNU, DSNU, and lens shading correction.
The line scan image sensor utilizes active CMOS pixels with pinned photodiodes to deliver high image quality whilst maintaining size, cost, and integration advantages of the CMOS process. The readout path permits pixel binning, increasing response and line rate. Windowing or sub-sampling allows a maximum line rate of 82,400 lines per second (lps) for 512-pixel window to be achieved.
