The principal ray or chief ray (sometimes known as the b ray) in an optical system is the meridional ray that starts at an edge of an object and passes through the center of the aperture stop. [5] [8] [7] The distance between the chief ray (or an extension of it for a virtual image) and the optical axis at an image location defines the size of ...
Since film cameras had better quality than early TV cameras. Early manufactures of Flying-spot scanners were Bosch Fernseh and Cintel. Cintel made Flying-spot scanners from the 1950s until the 2000s. [4] [5] [6] The flying-spot scanner tube had limit life span and quantity decease with use. Most flying-spot scanners use a green light that is ...

The angle of incidence, in geometric optics, is the angle between a ray incident on a surface and the line perpendicular (at 90 degree angle) to the surface at the point of incidence, called the normal. The ray can be formed by any waves, such as optical, acoustic, microwave, and X-ray. In the figure below, the line representing a ray makes an ...
Lens and ray diagram for calculating the circle of confusion diameter c for an out-of-focus subject at distance S 2 when the camera is focused at S 1. The auxiliary blur circle C in the object plane (dashed line) makes the calculation easier. An early calculation of CoC diameter ("indistinctness") by "T.H." in 1866.
