China laser pointer are adopting the most advanced wireless RF technology

Show program data and then transmitted to the U disk, complete laser scan control circuit. The advantage of this system can scan a variety of two-dimensional and even three-dimensional graphics and text, and animation effects. Compared to the previous calculator software control, the cost is greatly reduced, the control circuit is simple, easier to promote the application. This design collection optics, electronics, computers and other knowledge in one, is a multidisciplinary technical applications. The overall structure of the analysis and the block diagram. The overall structure of the analysis of laser light controller by the optical system, the drive circuit, interface circuit, control circuit is composed of four parts.  green laser pointer     all have a power switch.
Optical systems including lasers and two plane mirrors, the mirror angle is adjustable, using total internal reflection, in order to ensure good laser projection beam; drive circuit by the voltage amplifier and power amplifier two composition, its role is to provide a motor driven mirror rotation the required power. Drive and control circuits not a total ground power, digitally controlled analog switches to cut off the interference of the control object to the control circuit; interface circuit including digitally controlled analog switches, digital to analog converter and USB read-write interface.  laser pointer    is anti-interference.
Its main role is to digital conversion of the control circuit voltage analog to give the driver circuit and read U disk data; control circuit is the the AT89S52 minimum system completed its role in programming the motor running state, coordination and control the entire system job. 2.2 The whole block diagram of the control circuit digitally controlled analog switches 1 # D / A conversion 2 # D / A conversion data to read the motor X motor drive circuit Y optical system Figure 1.1 Overall block diagram of this design Chart works is: were installed in the amount of the motor shaft driven by the constant rotation of the mirror of a certain inclination, has to reflect the brightness of the beam by the laser beam space when a certain percentage of the mirror speed and turn combination The dynamic synthesis, a stable image on the receiver screen. It is a picture of   green laser   .
Change the size and polarity of the voltage on the two motor armature, motor reversible speed control, or manually adjust the fine adjustment knob attached to the mirror motor shell seat, change the inclination of the two reflector, you can get, such as clover rose lines, and a series of shapes and sizes, rich in content and geometry to 33 the whole hardware circuit design 3.1 Optical System 3.1.1 laser generator, laser generator is the light of the whole system, the laser display environment, the screen body and requirements to achieve the effect of configuration of different colors, different power lasers. General indoor display screen the closer body and the launch point distance, the lower power requirements.  china laser pointer are adopting the most advanced wireless RF technology.
Due to higher sensitivity of the human eye to red, low red laser generator power than other color laser generator power under the same conditions. The laser is used to display, the light intensity of 800-1200 lumens, has been able to meet the requirements of most people, it is the power of the laser display system in the tens of mW at 1 ~ 20W. This laser uses a wavelength of 0.63um semiconductor lasers because of their wavelength is similar 0.6328um can therefore replace the He-Ne laser red light, a small firm, difficult to damage, to make up for lack of a He-Ne laser. 3.1.2 Optical console optical console is the control part of the optical path, the laser display system including the optical system and control system. It makes a longer life span of the batteries of green laser pointer .
