Abstract

The invention discloses an interferometer zero path difference online debugging mechanism for a VISAR system. The objective of the invention is to solve the technical problems of great increase of theoperation complexity of an experimenter, reduction of the experiment efficiency and uncertainty of an experiment result due to judgment of whether an interferometer is in a zero path difference stateor not and a reset process after offline calibration in the prior art. A light source unit, a reflection unit, an adjustment unit and a feedback unit are integrated in the VISAR system; the online debugging of the zero path difference state of the interferometer is realized; the interferometer does not need to be moved out for off-line debugging, the automation level is high, the experiment operation is simplified, and the experiment efficiency is improved; and the zero path difference state of the interferometer can be detected on line, so that the uncertainty of an experimental result is avoided.

Description

technical field [0001] The invention relates to a debugging device for interferometer zero-path difference, in particular to an interferometer zero-path difference online debugging mechanism for a VISAR system. Background technique [0002] In the field of inertial confinement nuclear fusion, the Velocity Interferometer System for Any Refector (VISAR for short) is currently used to measure the velocity of the fusion shock wave. The imaging VISAR system is a kind of diagnostic measurement equipment, and the VISAR interferometric optical path is the core part of the system, which contains a large number of optical components. [0003] The VISAR system includes a light splitting and refraction module for dividing the working incident optical path R1 into the first working outgoing optical path C1 and the second working outgoing optical path C2, the first working outgoing optical path C1 and the second working outgoing optical path C2 respectively There is an interferometer; th...
