Laser self-mixing interferometry (SMI) harnesses the phenomenon of optical feedback by reinjecting a fraction of a laser’s output back into its cavity. This reinjection leads to an interference effect ...

A laser interferometer is the classic instrument of choice for measuring and compensating CNC machines and CMM machines in order to minimize downtime and make them more cost-efficient. CENTRIC ...

The relentless pursuit of higher precision in semiconductor lithography and atomic-scale manufacturing demands measurement systems capable of sub-nanometer accuracy, multi-axis capability, and robust ...

The European Space Agency (ESA) has launched the first payload of a mission designed to test optical hardware for detecting gravitational waves. The LISA Pathfinder mission, which blasted off from ...
