Viridian laser is the principle of what to read information recorded on an optical disk?

We usually say viridian laser is actually a component of the spindle motor, servo motor, the structure of the laser head and moving mechanical parts. And the laser head is composed of a lens group and a laser diode. Laser light from laser diode for generating and emitting laser, it can produce a wavelength of about 400nm (blue) -680nm (red) light in the laser head, a planar reflection prism of a very clever design.

viridian laser1

When CD-ROM in CD-ROM, sent from the photodiode signal converted into a laser beam, and then by plane prism to the disc. The CD is due to the uneven pits on behalf of “0” and “1” to record the data, so they accept viridian laser when the reflected light is weak the points.

viridian laser2

When the reflected viridian laser through the plane of refraction prism, the photodiode is changed into electrical signals, after conversion into a level control circuit, with only “0”, “digital signal 1″ signal, the computer can read the Cd contents. The laser wavelength is shorter, can distinguish more small bump pit is the same size of the optical disk storage capacity is higher.viridian laser3

When reading is played in the past by viridian laser, which is on the receiver to obtain binary convex discriminant information. Different wavelength of laser in determining the size of the disc can play information is not the same, because most if its minimum energy hole, which is intensive.

If you want to power, why don’t you learn to be a handheld gas viridian laser?

This is a hand-held, about 8Kg, 6 power lithium battery power supply, the output power of 60W, the end mirror and the discharge tube cooling cycle, the ignition can be 10 meters away, the picture is a cement wall was viridian laser burned to the melt dripping scene is very comfortable? Has tutorial in preparation, and has order all the accessories, when I filmed out. I hope more people can come into contact with the charm of science and technology!viridian laser1

Someone mentioned the security problem of viridian laser, I want to say is, than laser dangerous things everywhere, I do not know why so many know almost virgin heart, if the laser danger, rather than the 220V alternating current danger, bear children if the handle feels how to do? And far more destructive than the tens of watts of laser fireworks a variety of hand-held fireworks?viridian laser2

But indeed safety problem must not be underestimated, this also remind friends on this issue of concern, love science to science is a good thing, but we must ensure the safety, including the comments mentioned in the goggles protective measures are an essential tool for scientific experiments, there are risks in the production of viridian laser:

viridian laser3

Processing, large capacity power lithium battery power lithium battery, especially lithium batteries, can provide very large currents, generally can reach more than 10A, if in the process accidentally short-circuit, may cause fever, explosion risk. Viridian laser drive circuit, the circuit output can reach a maximum of 100 thousand volts, not only insulation measures to do a good job, but also to prevent the breakdown of air discharge, the degree of risk is very large, strongly recommended that there is no operating personnel not related professional knowledge, strongly recommended!

What will be the impact of the camera with viridian laser phone camera?

Viridian laser mobile phone camera exposure screen will display a large red edge white spots, removed after recovery after irradiation. The blue screen, digital camera, mobile phone screen display similar, and will show a red dot 4*4, may be several times of refraction reflection optical devices. It kept AF removed after thought the fault is, after a week and myself.viridian laser1

The lens of the spot is not smaller than the diffraction limit, the radius is approximately expressed as a 1.22f*lambda/D. that is to say, no matter what kind of lens, light can be focused to infinitely small. In addition, viridian laser is not only a parallel light, has a divergence angle and lens, the more powerful, light radiation after focusing more quickly. In other words, after focusing the light will only have larger power density in a small area.viridian laser2

Viridian laser as a weapon, is not to say that the light is focused on the OK, because of the strong power density time will have effect filamentation in air, the air breakdown will, the laser energy will be reduced, will introduce chirp, introduce various spectral components, will form a silk, will have a strong diffraction. In a word, as some characteristics of laser weapons will no longer exist.viridian laser3

Normally, each viridian laser scan can melt and re solidified layers of powder, the powder layer thickness is usually 20 to 150 m. in each time after laser irradiation the extra powder from the work area to scrape, and then repeat the above process until to construct a strong three-dimensional (3D) parts.
