machine vision lens

A machine vision lens is a specialized optical lens designed for use in machine vision systems, which are used for automated inspection, measurement, and quality control in industrial applications....

machine vision system

A machine vision system is an integrated combination of hardware and software components designed to capture, process, and analyze images to perform automated inspection, measurement, and quality...

magnetic bremsstrahlung -> synchrotron radiation

Radiation emitted by electrons when they travel in circular orbits at speeds close to that of light. Synchrotron radiation occurs in the x-ray and ultraviolet regions of the spectrum. Once considered...

magneto-optic shutter

A type of high-speed photographic shutter that uses Faraday rotation to produce exposure times as fast as 1 microsecond. It consists of two polarizers, set with their planes of polarization at right...

MEMS fiber optic switch

A MEMS fiber optic switch is a microelectromechanical system (MEMS) device designed to selectively route optical signals between multiple fiber optic channels. These switches utilize miniature...

modal bandwidth

Modal bandwidth is a crucial parameter in optical fiber communication systems, particularly in multimode fiber (MMF) systems. It quantifies the ability of a fiber optic link to transmit data at high...

motion sensing

Capacity of a vision system to capture an image of an object in motion and to resolve the direction and speed of that motion.

movement parallax threshold

The unequal angular velocities of two objects moving at equal speeds but at different distances from the observer, which are just noticeable.

MSM photodiode

A metal-semiconductor-metal (MSM) photodiode is a type of photodetector that consists of metal electrodes on a semiconductor material. Unlike the more common PIN photodiodes, which have a P-type and...

multimode group delay -> differential mode delay

Differential mode delay (DMD) is a parameter used to characterize the propagation characteristics of optical fibers, particularly in multimode fiber optic systems. It refers to the difference in...

multiple-beam laser

A laser having a Q-switching method that allows separate parallel volumes of the lasing material to act independently of each other and produce several separate beams. It is useful in high-speed...
