An integrated design of a time mark generator with high precision, high stability and high frequency was suggested. Obtained from the quartz crystal oscillator through the dividing network system as a driving source, the use of the GaAsP solid luminescent diode as the pulse light source and the use of the signal have advantages over other methods (mechanical, neon light tubes, discharge sparking, etc.). These advantages are: Light in weight, smaller in size, better in anti-seismism and less driving power. Because the luminescence wavelength coincides well with wavelength peak of the film sensitivization curve, the time mark frequency is very high (to 100Khz/s) and more stable. This generator is designed especially for the slit mode high-speed camera, and it can also be used for other synchrocameras.
