Curved Sensor for Vision Systems (CSVS)

ABSTRACT: This SBIR program aims to demonstrate a curved sensor array for a vision system (CSVS) capable of being integrated into small form factor. CBRITE"s approach to such a camera system is an active-matrix image array on curved substrate. The active-matrix array will consist of a metal oxide thin film transistor array on curved substrates upon which a polymer based broadband photo-detector will be incorporated. A state-of-the-art laser lithography tool will be employed for photoresist exposure patterning on a curved substrate. A detectivity D* of larger than 1012 cmHz1/2/W has been targeted for this system. BENEFIT: There is broad potential for commercial applications in the development of such large FOV image sensors; for example the vehicles that are automated or self-driving need large FOV image sensors for their sensing units in order to provide comparable FOV to the human eye. Also broad-band, large view cameras and sensors are utilized for general vehicles driving in foggy or rainy environments. Driving aid devices for dark, foggy or rainy situations are already integrated into high-end cars, but this program will develop low cost devices with the potential for including these features in cars for the entire car industry.
