Abstract:
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.
Abstract:
An optical Micro Electro-Mechanical System (MEMS) device provides an optical path retardation multiplier. The MEMS device includes a moveable corner cube reflector, a fixed mirror and a MEMS actuator. The moveable corner cube reflector is optically coupled to receive an incident beam and reflect the incident beam through 180 degrees towards the fixed mirror. The fixed mirror is optically coupled to reflect a reflected beam back towards the moveable corner cube reflector along a reverse path of the incident beam. The MEMS actuator is coupled to the moveable corner cube reflector to cause a displacement of the moveable corner cube reflector to extend an optical path length of the reflected beam.
Abstract:
An optical microscanner achieves wide rotation angles utilizing a curved reflector. The optical microscanner includes a moveable mirror for receiving an incident beam and reflecting the incident beam to produce a reflected beam and a Micro Electro-Mechanical System (MEMS) actuator that causes a linear displacement of the moveable mirror. The curved reflector produces an angular rotation of the reflected beam based on the linear displacement of the moveable mirror.
