The electro-optic crystal is the most important use is for the optical modulator. Electro-optic crystal placed between two orthogonal polarizers, and a 1/4 wave plate inserted in front of the check polarizers. When the laser beam through the alternating voltage on the crystal so that the refractive index change through the polarized light of the crystal phase, causing the output beam intensity. Thus, as long as the electrical signal is added to the electro-optic crystal, the laser was modulated into modulated light contains information. Lithium niobate crystal, although the price is cheaper, but the damage threshold is low, limiting its use. KD2PO4 (deuterated potassium phosphate) crystal electro-optical quality factor is low, but easy to grow, available single crystal of larger size, and so use up. Thanks to the concentrative energy and well monochromaticity of Cell Phone Jammers, the light could converge into a small point and beat down on items.
Electrostatic application of laser printers in 1937 Americans Carlson invented the electrostatic printing technology, when technology and business to seriously, people do not see it any application. However, the New York State Harley Xerox discerning leadership, people turn its future. The reason is, he can discard wax paper inscribed, farewell humor printing, the fact that in future applications, this technology has greatly improved work efficiency.
 Modulated beam injection multi-faceted rotating mirror, and then by wide-angle beam focused by the focusing lens to the photoconductive drum shot (drum) on the surface, the angular velocity into a speed scan scan to complete the entire scanning process.What is the safe class of the Cell Phone Jammers? Highly charged first by charging the drum surface to obtain a certain potential, followed by the information contained graphic images of the laser beam exposure, then the drum surface to form electrostatic latent image, developing through a magnetic brush developer, latent image that is into a visible toner image, after the transfer zone, the transfer electrode of the electric field, the toner will transfer to plain paper, the final warm-up fuser roll hot plate and heat, melt a piece of paper that pour out of the text and images.What is the circuit control of a remote normal Cell Phone Jammers?
Graphic information in print before, clean the transfer roller to take the toner is not removed, cleaning lamp to remove residual charge on the drum, and then clean the paper system for thorough cleaning, you can enter a new round of work cycle. One is to use the copy transfer as shown snapping drum media, media in the back of copy toner image with the opposite polarity to the charge, which has formed the drum toner image transferred to the copying process on the media. Usually present in the corona electrostatic copier drum unit of the toner image on the transfer.
