data compression
A method of storing digital data using techniques that consume less memory space than basic methods do. See differential pulse code modulation; run end coding; run length coding.
DCM
dispersion compensation module
definition test object
A chart, either printed on paper or prepared photographically on glass plates or film, that consists of 3-bar resolution test objects, sine-wave test objects for modulation transfer function...
deformable mirror device
A spatial light modulator consisting of a metallized polymer film stretched over an array of metal-oxide semiconductor field-effect transistors (MOSFETs). Each mirror element in the film can be...
differential pulse code modulation
A method of coding image data by storing in memory only differences in brightness of each pixel from that of its nearest horizontal neighbors: that is, it is the change in brightness rather than the...
diffuse modulation transfer function
Modulation transfer function of an optical element when used for transporting images from a lambertian source such as phosphors.
digital signal processing
Digital signal processing (DSP) refers to the manipulation and analysis of signals, which are representations of physical quantities that vary over time or space. In the context of DSP, these signals...
DMTF
diffraction-limited modulation transfer function
DPCM
differential pulse code modulation
DPPM
dynamic pulse position modulation
dynamic magneto-optical correlator
An optical correlator incorporating a binary phase-only spatial light modulator made from an iron garnet magneto-optic solid crystal and used in target recognition systems.
