OptSim for Sensing

OptSim for Sensor Systems

Photonic and fiber-optic sensors find applications in wide-ranging industry segments. The photonic sensors have many advantages over mechanical sensors: low power consumption, smaller size, a smaller number of moving parts, lower maintenance, and immunity to RF interference. Designing such systems require accurate modeling of sensor physics, optical phase, bidirectional signal propagation, and interferometry – all of which are supported in OptSim, making it an ideal tool for modeling photonic sensor systems for wide-ranging civilian, industrial, avionic and defense applications.
