Photonics Dictionary: R

A two-dimensional scanning process, in which a slow sector scan, propagated in one direction, is superimposed at right angles upon a rapid sector scan.

The scanning of a region in a given sequence of slender, straight parallel strips.

Also known as RAMP microscopy, random access multiphoton microscopy is a microscopic technique that uses multiple acousto-optic modulators to enable faster and addressable scanning of 3D cellular...

The pattern of lines traced by rectilinear scanning in display systems.
