Developments and achievements of optomechanical high-speed photography in China

Abstract

The theories and technologies of the optomechanical high speed photography, which has basically met the requirements in investigations of high speed, ultrahigh speed and other top scientific phenomena, have been developed and improved these years in China. Compared with the high speed photography with converter tube, the optomechanical high speed photography has a higher spacial resolution, larger image, and more frames since it only need one transfer from optical image to chemical image or charge image. Optomechanical high speed photographic techniques include high speed optics and mechanics, high speed optoelectronics, high speed electrooptical shutter, and high speed opto-optical technique. In this paper, we will introduce the technologies of high speed transporting film photography, ultrahigh speed rotating mirror photography, multiframe high speed photography with solid imaging unit, microscopy high speed photography, raster principle and Cranz-Schardin principle in high speed photography, and extreme high speed photography based on optical principles.
