81Ultrafast monochromator — In the diffraction of an ultrashort pulse (in the femtosecond, or lower, time scale) with a grating,apart spectral filtering, there occurs a time stretching due to the difference in the path length among the rays diffracted, even of equal… …
82Ultrashort pulse — In optics, an ultrashort pulse of light is an electromagnetic pulse whose time duration is on the order of the femtosecond (10 − 15 second). Such pulses have a broadband optical spectrum, and can be created by mode locked oscillators. They are… …
83Cube mapping — The lower left image shows a scene with a viewpoint marked with a black dot. The upper image shows the net of the cube mapping as seen from that viewpoint, and the lower right image shows the cube superimposed on the original scene. In computer… …

85Complex wavelet transform — The complex wavelet transform (CWT) is a complex valued extension to the standard discrete wavelet transform (DWT). It is a two dimensional wavelet transform which provides multiresolution, sparse representation, and useful characterization of… …
86Nova laser — Nova was a high power laser built at the Lawrence Livermore National Laboratory (LLNL) in 1984 which conducted advanced inertial confinement fusion (ICF) experiments until its dismantling in 1999. Nova was the first ICF experiment built with the… …
87Clipping (audio) — For shortening of voice snippets due to failures in voice activity detection, see squelch and voice activity detection. The altered peaks and troughs of the sinusoidal waveform displayed on this oscilloscope indicate the signal has been clipped.… …
88Mechanical resonance — This article is about mechanical resonance in physics and engineering. For a general description of resonance, see resonance. For mechanical resonance of sound including musical instruments, see acoustic resonance. For the music album by the… …
89Acoustic resonance — is the tendency of an acoustic system to absorb more energy when the frequency of its oscillations matches the system s natural frequency of vibration (its resonance frequency ) than it does at other frequencies. A resonant object will probably… …
