摘要:
An optical system, such as an integrated monolithic optical bench, includes a three-dimensional curved optical element etched in a substrate such that the optical axis of the optical system lies within the substrate and is parallel to the plane of the substrate.

A spectrometer with improved resolution includes a spectral domain modulator having a periodic response in the spectral domain to modulate a wideband source spectrum and cause one or more shifted bursts in the interferogram.
摘要:
A ring laser gyroscope (RLG) includes moveable mirrors and a Micro-Electro- Mechanical Systems (MEMS) actuator coupled to the moveable mirrors to cause a respective displacement thereof that induces a phase modulation on counter-propagating light beams relative to one another. The induced phase modulation creates an optical path difference between the counter-propagating light beams corresponding to a virtual rotation that reduces the lock-in of the RLG.
