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).
The detector integrates and converts the light signal into an output voltage, which is then digitised by an A/D converter and analysed by a computer. [ 3 ] Rows from a randomly permuted (for incoherence) Walsh-Hadamard matrix, reshaped into square patterns, are commonly used as binary test functions in single-pixel imaging.
BOSS GNU/Linux Version 10, featuring the Cinnamon Desktop Environment, is designed to further efforts in developing an e-Governance stack based on Free and Open Source Software (FOSS). The release aims to foster a robust FOSS community across industries, government, and academia, driving growth and contributing to a sustainable ecosystem in India.
An optical disc drive is a device in a computer that can read CD-ROMs or other optical discs, such as DVDs and Blu-ray discs. Optical storage differs from other data storage techniques that make use of other technologies such as magnetism , such as floppy disks and hard disks , or semiconductors , such as flash memory .

The IEEE Photonics Society, formerly the IEEE Lasers and Electro-Optics Society (LEOS), is a society of the Institute of Electrical and Electronics Engineers (IEEE), focused on the scientific and engineering knowledge about the field of quantum electronics.
In the history of optical storage media there have been and there are different optical disc formats with different data writing/reading speeds.. Original CD-ROM drives could read data at about 150 kB/s, 1× constant angular velocity (CAV), [1] the same speed of compact disc players without buffering.
Jean-Daniel Nicoud (born 31 August 1938), is a Swiss computer scientist, noted for inventing of a computer mouse with an optical encoder and the CALM (Common Assembly Language for microprocessors). [1] He obtained a degree in physics at the École Polytechnique Fédérale de Lausanne (EPFL) in 1963. Around 1965, he became interested in logical ...
