The invention relates to a camera debugging device and method, and in particular, relates to an offline debugging device and method for a multichannel pinhole camera. The invention provides the offline debugging device and method for the multichannel pinhole camera, and aims to solve the technical problems that when an existing offline debugging method for the multichannel pinhole camera is used for debugging a certain channel light path, the trend of other channel light paths is influenced, and the debugging difficulty is high. The invention provides a method for debugging the mutual relationamong four channel pinholes, a diaphragm and a target point of a multichannel pinhole camera by using a laser-illuminated micropore assembly as a simulation target, debugging a light path by using atheodolite and monitoring another light path by using another theodolite; the pinhole, the diaphragm and the simulated target light hole of each path are kept on the same straight line, and the offline debugging method of the multichannel pinhole camera improves the reliability and stability of online work of equipment.
Description
technical field [0001] The invention relates to a camera debugging device and method, in particular to an off-line debugging device and method for a multi-channel pinhole camera. Background technique [0002] The multi-channel pinhole camera is used to provide a suitable vacuum environment for the normal operation of the XRD detector array, and the target point is imaged on the image plane of the XRD detector through the multi-channel pinhole camera. This imaging system is applied to the Shenguang III prototype device The data measurement of the time evolution of the radiation flow in multiple areas such as the focal spot area, the re-emission area, and the target area inside the black cavity can provide high-precision experimental data on the radiation flow in the laser fusion physics research, and also provide a reference for the target area. Radiative flow diagnostics offer new approaches. At the same time, the multi-channel pinhole camera provides a stable structural su...
