The branch of science devoted to the study and measurement of the interaction of waves, such as electromagnetic waves and acoustic waves.
Note 1: The interaction of the waves can produce various spatial-, time-, and frequency-domain energy distribution patterns. [After 2196]
Note 2: Interferometric techniques are used to measure refractive index profiles, e.g., those of the preforms from which optical… (Read More →)

In digital data transmission, a sequence of bits transmitted between consecutive frames.
Note: Interframe time fill does not include bits stuffed within a frame.

In raster-scanned video displays, a scanning technique in which all odd-numbered scanning lines are first traced in succession, followed by the tracing of the even-numbered scanning lines in succession, each of which is traced between a pair of odd-numbered scanning lines.
Note 1: The pattern created by tracing the odd-numbered scanning lines is called the odd field, and the pattern… (Read More →)

Synonym interlaced scanning.

In cryptology, certificates in a certificate chain other than the first or end certificate.

In a central office or customer premises, a frame that (a) cross-connects the user cable media to individual user line circuits and (b) may serve as a distribution point for multipair cables from the main distribution frame (MDF) or combined distribution frame (CDF) to individual cables connected to equipment in areas remote from these frames.

In a network, a line-unit-line termination (LULT) or a line-unit-network termination (LUNT).

Synonym intermediate-field region.
