Silicon linear image sensors for photometry

Abstract

The paper describes a new linear image sensor for photometry by applying bipolar technology (Standard Buried Collector-SBC) to the manufacture of self-scanning linear photodiode arrays. On a monolithic chip we have designed 128 to 1024 linear photodiodes, demultiplexing system and signals processing system. A dynamic simulation and a real-time measurement have been implemented, that allow to take into account every operational phase of detection. The dialogue between the various functions in established by message's transmission, using common data areas stored on disks or in central memory of PC compatible computer.
