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?
