Optical choppers control transmission/blocking of Light are known and widely used in optical devices such as Optical Memory units, optical logic units, and optical communications devices.
Many applications utilize a high energy Laser beam to carry out certain functions. When utilizing lasers, in order to realize high precision and high repeatability in measurement, it is necessary to control the laser such that the Frequency of the Laser Beam coincides with a specific reference value. Optical choppers are used to modulate light beams or particle streams. By modulating optical beams or particle streams, optical choppers allow these signals to be measured accurately in environments with high ambient noise. Optical choppers control transmission/blocking of light are known and widely used in optical devices such as optical memory units, optical logic units, and optical communications devices. Optical choppers open and shut in response to an electrical waveform or pulse applied thereto, generally without moving mechanical parts. Optical/beam choppers can be designed to Absorb or reflect an energy beam and are also referred to as “interlock shutters”, “optical modulators”, or “optical shutters”.
