Optomechanical Sensing
This technology is an optomechanical sensor primarily designed for displacement and acceleration sensing. This sensor uses a novel AC measurement technique to reduce interference from low-frequency noise such as 1/f electronics noise. This technique involves modulating the length of a micro-optical cavity, which can be done with a relatively simple...
