Abstract

See full text

The disclosure discloses an optical path system for detecting a vacuum degree of a vacuum switch and a method thereof. In the optical path system, a plasma excitation unit excites pulsed laser along an excitation optical path to bombard a shielding case of a vacuum switch to be detected, so as to generate laser plasma; an optical path focusing unit focuses the excitation optical path and a collection optical path to focus the pulsed laser on the shielding case of the vacuum switch to be detected; the optical path focusing unit includes a visible laser device for generating visible light and an adjustment device for adjusting the excitation optical path; an image collection unit collects a laser plasma image and a visible light spot focusing image; the image collection unit includes a gated detector for collecting the visible light spot image and the laser plasma image via the collection optical path.
