Design And Realization Of Pulse Laser Energy Analysis System

The laser parameters have an important role in its applications. With the laser technology widely applied in people's life, the measurement of laser parameters also attracts more attention. Based on the rapid development of computer technology and CCD technology, there is a method to measure laser parameters with the CCD and the computer. Compared with traditional methods, the new method is a rapid measurement and the higher precision, but there are some deficiencies in measuring the energy parameters of pulsed laser.Based on the laser spot shooting business, this thesis introduces the basic principle and features of the CCD firstly and then, also introduces the common methods to measure laser parameters with CCD. Then, there is a question that when measuring pulsed laser parameters, it can not acquire complete laser spot, because the pulse of the pulse laser is too short. So, it proposes a method that it is captured with the trigger model. On the one hand, it selects the appropriate hardware equipment, and on the other hand it designs appropriate software system. According to the actual situation, it uses the SDK to develop the image acquisition program and use the Matlab and VC++ to develop image analysis program in the realization of software systems, and has formulated a communication protocol about the COM based on the RS232.This protocol is easy to understand and scalability and it includes communications in all cases. It can be proved that it adapts to analysis system of the energy of pulsed laser in the practice, and it has had good results. I have completed all the function of the system, and it can achieve analyzing the energy of pulse laser. At last, I have all the paper work done by a summary and actual results, and in light of the problems, I have some ways to improve and the outlook in the next step.
