PRINCIPLES OF OPTICAL DEVICES‚NAME AND EXPLAIN FEW ! ANS:Storage and retrieval of data on optical disks can be described in two simple steps. First‚ data marks are recorded on a surface. Data marks can be prerecorded‚ like on a music CD‚ or they can be recorded by users on blank disks‚ like with CD-recordable products. The second step is retrieval of information from the disk‚ where a light beam scans the surface. Modulation in the reflected light is used to detect the data-mark pattern under

Optical illusions are all around us(explain). The brain remembers what it has seen before‚ then when it sees something similar it takes shortcuts when looking at a new images. This causes the brain to make mistakes and creates optical illusions. An optical illusion is a misleading image that deceives the eye. Different people see optical illusions differently because of their previous experiences. Previous experiences help the brain interpret what it sees. If your previous experiences determine

1. Introduction Blu-ray is a new optical disc standard based on the use of a blue laser rather than the red laser of today’s DVD players. The standard‚ developed collaboratively by Hitachi‚ LG‚ Matsushita (Panasonic)‚ Pioneer‚ Philips‚ Samsung‚ Sharp‚ Sony‚ and Thomson‚ threatens to make current DVD players obsolete. It is not clear whether new Blu-ray players might include both kinds of lasers in order to be able to read current CD and DVD formats. The new standard‚ developed jointly

Executive Summary Optical fibres are being increasingly used in the telecommunications industry. They are slowly replacing the conventional copper cables due their superior ‘data transmission’ properties. They transmit data via light pulses within glass or plastic strands. Fibre optics fit the material requirements for good data transmission since they are ability to transmit and preserve quality of signals‚ durable and cost-effective. Some of the current materials employed within the industry
