The receiver of green laser pointer can be added memory function

The receiver of green laser pointer can be added memory function.Clients can decide the functions of the receiver of green laser pointer
⒈ it is a very realistic three-dimensional like it, and observed exactly the same kind, has the same visual effect. ⒉ the hologram can be divided into several small pieces, each piece can be a complete reproduction of the original things like (like the Monkey King places at once). ⒊ on the same sheet of film, after repeated exposure, they can overlap many images, but can not like each other's interference as shown separately, that is a floor can also record a number of features. The receiver of green laser pointer could be manufactured according to clients’ requirements.⒋ hologram easy to copy. ordinary light to reproduce, three-dimensional color television, color stereo movies. five, some applications of holographic interferometry ⒉ ⒈ holographic holographic microscopy ⒊ holographic technology in oceanography Applications ⒋ holographic optical elements produced holographic anti-counterfeiting technology ⒌ VI laser alignment measurement techniques straightness of the column is a series of dots or continuous surface geometry of a straight line relative to the distance, straightness measurement is flat, parallel , vertical and other geometric measurement basis direct measurement of the laser appears whichever opens up new avenues laser collimator works can be divided by the amplitude measurement, interferometry and polarization measurements.Clients can decide the functions of the receiver of green laser pointer. One laser alignment measuring principle 1 wedge interference method laser interferometer method Second, the composition of the laser collimator 1 laser collimated beam expander optical system 3 photodetectors and processing circuits (1 ) four-quadrant photocell horizontal and vertical direction of the output are: which can probe beam center. (2) PSD Third, the application of laser alignment measurement 1 does not directly measure the degree 2 different VII of the laser axis is measured carrier temperature measurement a laser carrier temperature measurement principle using laser as a carrier, modulated laser with temperature information, and then the laser with temperature information transmitted to the receiver through the space portion, the signal processing to achieve measuring temperature. It is easy to learn how to use the green laser pointer. Second, the composition of the laser carrier temperature measurement system pulse modulation many ways, a pulse amplitude modulation, pulse width modulated, pulse frequency modulation, etc. Here the use of pulse frequency modulation, as shown: transmitter add content : single-junction transistor only one PN junction as the emitter and base of the two three-terminal semiconductor devices, early known as the double base diode. features: The typical structure is a uniform high resistivity of the lightly doped N type single crystal semiconductor as the base area, the two ends make ohmic contact base, the base area in the center or one of a very biased position of heavily doped with shallow diffusion as emitter PN junction is made (Figure a) When the base voltage is applied between the B1 and B2 (Fig. b), current flows from B2 B1, and in the end zone at the base of the formation of B1 of the potential anti-state bias, if a B signal is applied to the emitter, and this signal is more than the original anti-bias potential, the device was conductive state when there is partial state.
