Details of Blu Ray Technology, LASER in Blu Ray Technology, Lens & Layers in Blu Ray Technology:

Blu-ray is a high-density optical disc format used for storing high-definition video and other data. The technology was developed by the Blu-ray Disc Association (BDA) and offers significantly higher capacity than traditional DVDs.

LASER in Blu-ray Technology:
Blu-ray uses a blue-violet laser with a wavelength of 405 nm, which is shorter than the 650 nm red laser used in DVDs. This allows the laser to focus more precisely and read smaller pits and lands on the disc, resulting in greater storage capacity and higher data transfer rates.

Lens & Layers in Blu-ray Technology:
Blu-ray discs have a total diameter of 12 cm, the same as CDs and DVDs. However, they use a different optical system to read the data. The Blu-ray disc uses a special lens and a single-sided, dual-layer disc with a capacity of 50 GB. The lens has a numerical aperture of 0.85, which is greater than the 0.6 NA used in DVDs. The disc consists of a polycarbonate substrate, a recording layer, a semi-reflective layer, and a protective layer. The recording layer consists of a thin film of organic dye or inorganic material that changes its reflectivity when exposed to the laser.

TV Engineering:
TV engineering is a field that focuses on the design, operation, and maintenance of television systems. This includes the development of new technologies for broadcasting, cable, satellite, and digital television systems. TV engineering involves understanding the physics of television signals, the design of electronic circuits and systems, and the use of software to control and optimize television equipment. This field is also concerned with the design of broadcast studios, production equipment, and post-production facilities. TV engineering is a highly specialized field that requires extensive knowledge of electronics, physics, and computer science.
