A sputter-resistant optical system adapted to the vacuum plasma characteristics of an electric thruster

Abstract

The application relates to the field of aerospace testing technology, in particular to a sputtering-resistant optical system adapting to the vacuum plasma characteristics of an electric thruster, which comprises a mounting platform, an optical camera mounting box, a lens rotating device and a sputtering-resistant baffle, wherein: a fixed support is arranged below the mounting platform; the optical camera mounting box is fixed on the mounting platform and comprises a camera box body and a camera lens barrel; the lens rotating device is fixed on the mounting platform through a rotating shaft support; and the sputtering-resistant baffle is fixedly connected with the lens rotating device. The application can realize multiple optical observations without frequent replacement of optical lenses, can effectively resist plasma sputtering, greatly increases the observable time, solves the problem of reduced observation performance caused by plasma coating in a short time of a conventional optical observation system, improves the observation effect and work efficiency, and guarantees the definition of imaging resolution.
