WHAT IS THE 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

OPTICAL PACKET SWITCHING Kunal K Mehta(11BEC107) Electronics and communication branch Institute of Technology‚ Nirma University Ahmedabad 11bec107@nirmauni.ac.in Abstract: Optical packet switching promises to bring the flexibility and efficiency of Internet to transparent optical networking technology with bit rate extending beyond that is currently available with electronic router technologies. New optical signal processing have been demonstrated that enable routing at bit rates from

Mie resonances in dielectric particles can increase the local optical density of states (LDOS) associated with either electric or magnetic transition rates in nearby quantum emitters without ohmic losses. Their rather large quality factors compensate their low field confinement as compared to the plasmon resonances of metallic nanostructures for which nonradiative decay channels dominate. We show theoretically that near-infrared quadrupolar magnetic resonances in silicon particles can preferentially

3M Optical Systems: Case Brief As Andy Wong‚ how would you handle the authorization for expenditure for the re-launch of the privacy screen? As Andy Wong‚ I would take the proposal to one of my senior-level mentors for support. The OS unit has already tried and failed three times with the microlouvered filter and high level support would benefit both Wong and Guehler in this case. If Guehler sees that other areas of 3M are in support of the authorization for expenditure‚ then he will not have

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

Optical Storage Devices • An optical disk is a high-capacity storage medium. An optical drive uses reflected light to read data. • To store data‚ the disk’s metal surface is covered with tiny dents (pits) and flat spots (lands)‚ which cause light to be reflected differently. • When an optical drive shines light into a pit‚ the light cannot be reflected back. This represents a bit value of 0 (off). A land reflects light back to its source‚ Representing a bit value of 1 (on)

Do Boys and Girls See Optical Illusions Differently? [pic] Do Boys and Girls See Optical Illusions Differently? The goal of this paper is to focus on how gender affects what people see in optical illusions. The differences of male and female brains affect how boys and girls act and perceive the world. If there’s a difference in the vision of boys and girls then there will probably be a difference in how they see an optical illusion. Studies show that there are multiple differences in the

Synthesis‚ Spectral‚ and Antibacterial Studies of Silver Nanoparticles and Silver(I) Complex of 2-Mercaptobenzothiazole Abstract : Microbes‚ such as bacteria‚ molds‚ yeasts‚ and viruses‚ in living environment are often pathogenic and cause severe infections in human beings. Therefore‚ there is a pressing need to search for new antimicrobial agents from natural and inorganic substances [1]. Antimicrobial nanoparticles mainly consist of metals‚ metal oxides‚ and many biologically derived materials
