Alhazen's work on optics is credited with contributing a new emphasis on experiment. His main work, Kitab al-Manazir (Book of Optics), was known in the Muslim world mainly, but not exclusively, through the thirteenth-century commentary by Kamāl al-Dīn al-Fārisī, the Tanqīḥ al-Manāẓir li-dhawī l-abṣār wa l-baṣā'ir.

Laser science—research into principles, design and application of these devices—became an important field, and the quantum mechanics underlying the laser's principles was studied now with more emphasis on the properties of light, and the name quantum optics became customary. As laser science needed good theoretical foundations, and also ...
Family watching TV, 1958. The concept of television is the work of many individuals in the late 19th and early 20th centuries. The first practical transmissions of moving images over a radio system used mechanical rotating perforated disks to scan a scene into a time-varying signal that could be reconstructed at a receiver back into an approximation of the original image.

George R. Carey (1851–1906) was an American inventor. He was among the first to propose the telectroscope using the photoelectric properties of selenium as a means for transmitting images—a precursor to modern television. George R. Carey was a professional surveyor employed by the City of Boston.
Jan Szczepanik (June 13, 1872 – April 18, 1926) was a Polish inventor, with several hundred patents and over 50 discoveries to his name, many of which are still applied today, especially in the motion picture industry, as well as in photography and television.
The elements of a simple broadcast television system are: . An image source. This is the electrical signal that represents a visual image, and may be derived from a professional video camera in the case of live television, a video tape recorder for playback of recorded images, or telecine with a flying spot scanner for the transfer of motion pictures to video).
A field-sequential color television system similar to his Tricolor system was used in NASA's Voyager mission in 1979, to take pictures and video of Jupiter. [2]There was a Mexican science research and technology group created La Funck Guillermo González Camarena or The Guillermo González Camarena Foundation in 1995 that was beneficial to creative and talented inventors in Mexico.
