Paper Abstract

The design and performance of a machine vision camera fabricated in thick film microcircuitry is described. The camera is manufactured with either a 128x128 or 256x256 pixel image sensor mounted onto a hybrid microcircuit. The 256x256 pixel front hybrid is constructed using multiple stratified layers of conductor on dielectric. Resistors are screened and trimmed on top of dielectric, a state-of-the-art procedure. Both 128x128 and 256x256 cameras use a common rear substrate which incorporates the clocking circuitry for the camera. The hybrids are formed into a "sandwich" around an aluminum heat sink and differential I/O lines are taken to the camera interface connector by means of a flexible printed circuit. Video pixel rates to 8 MHz are obtainable from both cameras which allow frame rates to 380 frames per second with the 128x128 version. Additional camera features permit the user to activate a real time frame reset as well as take external control of the row clock for even higher speed image processing.
