BPN922: Analog Optical Voltage Sensor


Distributed sensors are becoming ubiquitous in manufacturing, automotive, and consumer applications. One extremely common need at the core of many of these sensors is the requirement to sense small voltages (uV-mV scale), amplify, digitize, and then communicate those bits so they can be acted on. We are taking a different approach - by utilizing nonlinear optical materials, we plan to transduce these signals directly into reflected light, removing the need for complex and high-cost sensor-side circuitry. Since the mechanism is purely passive and does not require a continuous power supply, these sensors have the potential to be extremely robust where line-of-sight optical communication is a possibility.
