carrier

An analog signal capable of being modulated as to frequency, amplitude or phase to carry information.

cathode modulation

The amplitude modulation through the application of modulating voltage to the cathode circuit.

central processing unit

The computer module whose circuitry interprets instructions and guides the actions of the peripherals. Also known as the mainframe.

chopping frequency -> modulation frequency

Rate at which optical radiation or a signal is varied through the use of a mechanical or electronic chopper. Also called chopping frequency.

coherent communications

A fiber optic communications system that works on the principles of homodyning or heterodyning. The transmitting laser produces an optical wave that is modulated in amplitude, phase or frequency by...

companding

A deliberately nonlinear amplitude modulation that strengthens weak signals and reduces strong signals for transmission.

computer-generated hologram

A computer-generated hologram (CGH) is a holographic image produced using computational methods and algorithms, rather than traditional optical techniques. CGHs are generated entirely in digital form...

continuous wave

Continuous wave (CW) refers to a type of signal or transmission where the signal is constant and does not vary with time. In various contexts, the term is used to describe continuous, uninterrupted...

contrast transfer function -> modulation transfer function

Also called sine wave response and contrast transfer function. The modulation transfer function is the ratio of the modulation in the image to the modulation in the object as a function of frequency...

correlator -> optical correlator

A device incorporating a spatial light modulator and a reference filter; used for matching an input optical waveform or signal with stored data in a photonic computer. This technique is done using...

CTLM

charge-transfer light modulator

CubeSat

A CubeSat is a type of miniaturized satellite characterized by its standardized size and modular design. CubeSats are typically used for scientific research, technology demonstration, educational...
