Current optical data storage media, such as the CD and DVD store data as a series of reflective marks on an internal surface of a disc. In order to increase storage capacity, it is possible for discs to hold two or even more of these data layers, but their number is severely limited since the addressing laser interacts with every layer that it passes through on the way to and from the ...
A standard DVD case is a single-piece plastic case with two creases, which folds around and snaps closed. It measures 135 mm × 190 mm × 14 mm (5.31 in × 7.48 in × 0.55 in). It is wrapped on the outside by a thin piece of transparent plastic that can hold a paper label. The label measures 284 mm × 184 mm (11.2 in × 7.2 in).
[1] [2] This side of the disc contains the actual data and is typically coated with a transparent material, usually lacquer. The reverse side of an optical disc usually has a printed label, sometimes made of paper but often printed or stamped onto the disc itself.
Optik: International Journal for Light and Electron Optics, or simply Optik (German for Optics) is a peer-reviewed scientific journal covering the optics of light and electrons. According to the Journal Citation Reports , the journal has a 2021 impact factor of 3.1.
Optical computing or photonic computing uses light waves produced by lasers or incoherent sources for data processing, data storage or data communication for computing.For decades, photons have shown promise to enable a higher bandwidth than the electrons used in conventional computers (see optical fibers).
In May 2015, net SE created a new subsidiary, Meyer Optik USA Inc., to distribute Meyer-Optik-Görlitz brands in the United States. Meyer Optik USA is headquartered in Atlanta , GA . That same year, net SE - Globell Deutschland launched a Kickstarter campaign to produce the Trioplan f2.9/50, a special new lens that revived the tradition of a ...
In the Book of Optics, al-Haytham hypothesized the existence of primary and secondary light, with primary light being the stronger or more intense of the two.The book describes how the essential form of light comes from self-luminous bodies and that accidental light comes from objects that obtain and emit light from those self-luminous bodies.
[3] Advanced Photonics Nexus, co-published by SPIE and Chinese Laser Press, publishes novel results of high significance and broad interest in all areas of optics and photonics. It is the sibling journal of Advanced Photonics. Journal of Applied Remote Sensing (JARS) is an online-only, quarterly published journal on remote sensing.
