Time base correction (TBC) is a technique to reduce or eliminate errors caused by mechanical instability present in analog recordings on mechanical media.. Without time base correction, a signal from a videotape recorder (VTR) or videocassette recorder (VCR), cannot be mixed with other, more time-stable devices found in television studios and post-production facilities.
A Hieronymus machine is any of the patented radionics devices invented by electrical engineer Thomas Galen Hieronymus (21 November 1895 – 21 February 1988). [1] Hieronymus received a U.S. Patent for his invention in 1949, which was described in the patent application title as a device for "detection of emanations from materials and ...
The Enigma machine is a cipher device developed and used in the early- to mid-20th century to protect commercial, diplomatic, and military communication. It was employed extensively by Nazi Germany during World War II, in all branches of the German military. The Enigma machine was considered so secure that it was used to encipher the most top ...
Ophthalmology. In ophthalmology, horror fusionis is a condition in which the eyes have an unsteady deviation, with the extraocular muscles performing spasm-like movements that continuously shift the eyes away from the position in which they would be directed to the same point in space, giving rise to diplopia. Even when the double vision images ...

A Glan–Taylor prism reflects s -polarized light at an internal air-gap, transmitting only the p -polarized component. The optical axes are vertical in the plane of the diagram. A Glan–Taylor prism is a type of prism which is used as a polarizer or polarizing beam splitter. [1] It is one of the most common types of modern polarizing prism.
Dichroic prism. A dichroic prism is a prism that splits light into two beams of differing wavelengths (colour). A trichroic prism assembly combines two dichroic prisms to split an image into 3 colours, typically as red, green and blue of the RGB colour model. They are usually constructed of one or more glass prisms with dichroic optical ...
Prism spectrometer. A prism spectrometer is an optical spectrometer which uses a dispersive prism as its dispersive element. The prism refracts light into its different colors ( wavelengths ). The dispersion occurs because the angle of refraction is dependent on the refractive index of the prism's material, which in turn is slightly dependent ...
