laser pointer will be tested in the testing center of laser pointer

Production Supervision of laser pointer
Graphic projection is not easy to flicker. In actual use, not to set the scan rate the higher the better. It also required the user to output the graphics appropriate adjustments. Scanning step. Users to draw graphics using laser projection software can find a drawing by a number of discrete trajectory in the graph "nodes" consisting of. The so-called "step" is the distance between these points. As a graph, the smaller the output steps more graphics "realistic", but the composition graph "nodes," the number will increase. If the graphics are too many points, it will cause the flashing graphics output. The new production line of laser pointer will greatly increase the output of laser pointer .
Therefore, the setting step to combine the output graphics of the "realistic" level, and the graphics are flashing and other factors considered. Another step of setting, with the scan rate. In general, the faster scan rate, the smaller the step size should be set? Laser switching point is often set in a continuous line of the two endpoints (see below). The reason for setting the switching point is that in a continuous line between the laser output state to change, may be closed to start from, it may be from start to close. These state changes are usually laser is instantaneous, and electromagnetic scanner because it is driven by mechanical scanning, so there is the actual speed of the scanning process and mechanical lags inertia. If the computer is sent to the scanner end of the position signal, it changes the state to send the signal laser, you will see in the output graph, the position of the laser changes the state is not required in your position. laser pointer will be tested in the testing center of laser pointer .  
The general direction of the long side with flat-top distribution (Top-Hat), the other is up nearly Gaussian distribution, or nearly flat distribution in between. Although the excimer laser light field distribution uniformity is already higher than the general non-uniformity of excimer laser is better, but because of excimer lasers in the large volume, high voltage, high-pressure state operation, easily lead to uneven discharge gain, and if the proportion of working gas changes, changes in the output pulse energy at the same time, the intensity of the beam cross-section distribution of considerable change occurred, resulting in the output light intensity distribution fluctuated considerably, from the practical application there is a gap. The new manufacture base of laser pointer draws a lot of attention.New Manufacture Base of laser pointer
In order to improve the quality of the laser beam can be used in excimer laser beam uniformity are: prism method, reflection microscopy, two compound eyes are beam-type device, the phase grating diffraction method, optical waveguide method and so on.
