Abstract

Abstract

The basic physical properties, the methods about the detection of character parameters, and the signal disposal of back streaming ions are analyzed. A program about laser interferometry is designed. The strongpoint and disadvantage of the program are introduced briefly. Based on the concrete experimental test, approaches for high quality images are summarized. Dynamic interferometry image would be obtained through adding a cutdown lens between the output of laser interferometry list and the framing camera. The signal-to-noise of measured images would be improved through shielding the framing camera using plumbum and some other heavy metal materials. Within 6μs, the state information of back streaming ions can be obtained by changing delay and time space. Through analysis and disposal of
- back streaming ions,
- laser interferometry,
- x-ray source,
- spot,
- character parameters
