Abstract

The invention provides a calibration system for deflecting direction of a streak tube and a cathode surface. The calibration system for the deflecting direction of the streak tube and the cathode surface comprises a deflecting direction calibration system and a cathode surface calibration system. A fixing guide rail of the deflecting direction calibration system is arranged on a first optical table. A parallel optical tube, a calibrated streak tube and a CCD are arranged on corresponding sliding blocks of the fixing guide line. The CCD and a displayer collect and display a final image of the cathode surface of the streak tube. A second optical table of the cathode surface calibration system is provided with a light through hole, and a horizontal plane reflecting mirror is arranged on the second optical table and directly faces the light through hole. A laser light source is arranged below the second optical table, and an adjustable plane reflecting mirror is arranged below the second optical table and directly receives a laser reflected by the horizontal plane reflecting mirror. A receiving screen receives the laser reflected by the adjustable plane reflecting mirror. The encapsulation accuracy of the streak tube and the efficiency of the whole machine integration of a streak camera are improved, and the calibration system for deflecting direction of the streak tube and the cathode surface is beneficial to the advancement of the industrialization of the streak camera.

Description

technical field [0001] The invention relates to a calibration method for the deflection direction and cathode surface of a stripe image transformation tube, in particular to a calibration method for the deflection direction and cathode surface of a stripe image transformation tube, a core component of a stripe camera. Background technique [0002] Ultrafast phenomena (duration less than 1 μs) widely appear in natural or scientific and technological research. For example, the photosynthesis process of plants, the electrical pulse generated by VLSI, the carrier lifetime of semiconductor materials, the ultrafast photoexcited state relaxation process in laser materials, the molecular dynamics process of chemical reactions, the fluorescence emission of biological materials , The duration of ultrashort laser pulses generated by lasers, the physical process of interaction between strong light and matter, etc. are mostly in the range of picoseconds to femtoseconds, or even attosecon...
