| Summary |
A sensor inspired by the vision system of the common housefly has been developed at the University of Wyoming that exhibits hyperacuity by using overlapping sensor sensitivity fields. This sensor has been tested and characterized under tightly controlled laboratory settings with very positive results. Every time the sensor is used things such as temperature can affect the sensitivity fields and the sensor must be re-characterized. Currently, this characterization is done by adjusting each of the potentiometers of the sensor by hand. For this sensor to be applicable in real world situations, it must be able to characterize itself and adjust the potentiometers. My research project involves developing a system using digital potentiometers controlled by a microprocessor that would provide automatic characterization of the sensor. This sensor is equipped with automatic gain control circuitry that allows it to be adapted to various lighting conditions. The system I am developing is a part of a larger project with the goal of making the sensor capable of adjusting to ambient light conditions for functionality beyond tightly controlled laboratory settings.
