Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with accompanying drawing:

[0025] Step 1: CCD or CMOS image sensor is coupled with an image intensifier to form an ICCD or ICMOS camera. The coupling structure is as follows figure 1 As shown; in the figure, 1 is an image intensifier, 2 is a coupler, and 3 is an image sensor;

[0026] Step 2: In the coupled ICMOS or ICCD imaging system, the image intensifier and image sensor can independently control the exposure, and the control signals are EXP MCP and EXP SENSOR ;

[0027] Step 3: The experimental system gives the pre-trigger signal TRIG PRE , the image capture system enters the state of waiting for a random process; the experimental system here refers to the system that produces ultrafast physical processes, and the image capture system refers to the system that captures images of ultrafast processes, and the two are the relationship between experiment and test;

[0028] Step 4: The ...

Abstract

The invention proposes an image capture method of an ultrafast random physical process, which solves the problem that it is difficult to accurately capture a single physical process image with conventional image capture methods, and is especially suitable for single particle track imaging of random particle events. The imaging system used in this method is obtained by optically coupling an image sensor and an image intensifier, where the exposure control of the image intensifier and the image sensor are independent of each other; using the independent exposure control function of the image intensifier and the image sensor, a pre-trigger is provided through the experimental system and a post-trigger signal to achieve stable and reliable capture of a single image for an ultrafast random physical process. Image acquisition capabilities for process experiments.

Description

technical field [0001] The invention relates to an image capture method of an ultrafast random physical process, in particular to an image capture method that can be applied to an ultrafast random physical process in modern applied physics experiment research. Background technique [0002] Image capture of ultrafast physical processes is an important part of modern applied physics experimental research, and an important testing technique for experimental verification of theoretical physics research. According to the probability of their occurrence, physical processes can usually be divided into two types: one is the definite time physical process, this kind of physical process passes through a definite time after the experimental system reaches the conditions for the physical process to occur (the definite time referred to here, It means that the duration of the physical process is much longer than the uncertainty of the occurrence time of the physical process), and the phys...
