Parallel testing procedures, is my 2003 in Shanghai Laser Technology Research Institute, prepared during the work, the main objective was to test the parallel port control through acousto-optic modulator of the pulse width and frequency has reached the control of laser marking machine laser beam state The purpose, as different pulse width and frequency of the laser beam at the object surface, marking out the effect is different. Of course, the test procedure can also be used for other needs of different parallel output of the square wave pulse width or frequency of applications. The procedure has been applied WinIO proceedings, it can also be controlled under WinNT parallel. Lee flyskywhy@gmail.com
