Abstract

We provide the theory of operation of a recently proposed sensor array. The sensor is designed to detect changes in incident optical intensity that result when a non-uniform intensity distribution on the sensor is displaces laterally. This property allows the device to be used for optical vibration detection. The sensor is based on four-point measurements of photoconductance, which makes the device scalable and easy to fabricate. Some preliminary experimental results obtained with a prototype are given.
