Design Of Remote Measurement And Control System For Streak Camera Based On LabVIEW

Streak camera is a very useful diagnostic equipment to study the inertial confinement fusion (ICF) driven by laser, it is also an essential equipment in studying the ultra-fast laser pulse. With the fast development of the inertial confinement fusion technology, some new funtions of the streak camera system are proposed, which are the abilities to remote measure and control the state parameters for streak camera. Reaserch of the thesis is focused on the remote measurement of the work environment, image precessing, remote control of the diagnostic modes and analysis of the factors that affect camera's resolusion for the streak camera.The main works include the following four aspects:1.The principles and engneering applications of the streak camera are briefly introduced, the needs of remote measurement and control for the streak camera are analyzed in details Based on the analysis, the overall plan of the remote measurement and control system for the streak camera, which is using PC 104 plus computer and PC 104 multifunction data acquisition card as the main hardware of the system and the virtual intstrumens language LabVIEW as the software development kit, is worked out.2.The programs of remote measurement system, streak image processing system and control system are separately developed with LabVIEW. The measurement system is able to achieve the task of the the acquisition of the environment parameters which are the temperature, pressure, humidity of the streak camera, the temperature, pressure, flow and the leakage signal of the cooling system. The method of software linear least square fit is adpplied to caliberate the nonlinear error of the sensors. The streak image processing system is able to achieve the processing of the streak image,which contains the information of the laser pulse's time and energy, and can gain the laser pulse's half width time, density, rising time and fall time. The control system is able to achieve the control of the high voltage, delay time, working mode and high voltage power management. The high voltage output in the control system is also caliberated.3.The plan of realizing the remote measurement and control is made via the combination of the C/S and B/S modes which are respectively based on the technologies of LabVIEW DataSocket and Remote Panel. Experiment of the remote measurement and control system is carried out.The results show that customer could remotely control the camera via Web explorer and could obtain the environment parameters via program of the remote measurement system that based on DataSocket.4.The factors that affect streak camera's resolution are analyzed. The analysis focuses on the factors of the sweep non-linear error and the delay error. The ways of improving the resolution of the streak camera is also proposed.
