Glossary of machine vision

The following are common definitions related to the machine vision field.

General related fields

is the stored energy in the cavity, and

The optical Q is equal to the ratio of the resonant frequency to the bandwidth of the cavity resonance.

If the Q factor of a laser's cavity is abruptly changed from a low value to a high one, the laser will emit a pulse of light that is much more intense than the laser's normal continuous output.

The CIE 1931 color space chromaticity diagram. The outer curved boundary is the spectral (or monochromatic) locus, with wavelengths shown in nanometers. Note that the colors depicted depend on the color space of the device on which you are viewing the image, and no device has a gamut large enough to present an accurate representation of the chromaticity at every position.
