cathode-ray oscilloscope -> oscilloscope

A system in which a supplied signal causes the deflection of the electron beam in a cathode-ray tube, thus forming a visible trace on the phosphor screen of the tube and providing for examination of...

catoptric system

An optical system in which the only image-forming elements are curved-surface mirrors; e.g., a Cassegrain lens system.

concave

Concave is an adjective used to describe a surface or shape that curves inward or has a hollow or recessed appearance. In the context of geometry or optics, a concave shape is one that curves or...

concave and convex spherical mirror

Concave and convex spherical mirrors are types of curved mirrors that have surfaces shaped like segments of spheres. These mirrors are commonly used in optics for various applications, including...

contrast transfer function -> modulation transfer function

Also called sine wave response and contrast transfer function. The modulation transfer function is the ratio of the modulation in the image to the modulation in the object as a function of frequency...

convex

Convex is an adjective used to describe a surface or shape that curves outward, bulges, or has a rounded and outwardly extending appearance. In the context of geometry or optics, a convex shape is...

corner cube

A corner cube, also known as a corner reflector or retroreflector prism, is a type of optical device used to reflect light or electromagnetic waves back towards their source with minimal deviation in...

corner-cube prism -> corner cube

corner-cube reflector -> corner cube

cube-corner prism -> corner cube

cutback technique

A technique for measuring fiber attenuation or distortion by performing two transmission measurements. One is at the output end of the full length of the fiber. The other is within 1 to 3 m of the...

cutting

The process of forming a lens to a given pattern, or of cutting a piece of glass along the line of scratch.
