Device and method for detecting vibration isolation performance consistency of oversized optical platform

Abstract

The invention discloses a device for detecting the vibration isolation performance consistency of an oversized optical platform. The left end of a central line on the optical platform is provided with a bracket; the right end of the central line on the optical platform is provided with a display screen; the left side of the bracket is provided with a laser; the wavelength of the laser is 632.8 nanometers; the laser is provided with a CCD (Charge Coupled Device) camera which is connected with a computer through a lead; the right side of the laser is provided with a beam splitter along a central line emitting direction bracket in the length direction of the optical platform; at least six even number left reflecting mirrors are arranged in the laser emitting direction of the beam splitter on the optical platform; the optical platform along the light reflecting directions of the left reflecting mirrors is provided with water-filled water grooves of which the quantity is the same as that of the left reflection mirrors; a light diaphragm is arranged in the light reflecting direction of the left reflecting mirror at the upper end of the central line of the left side wall of each water groove; the optical platform in the inner water surface light reflecting direction of each water groove is provided with right reflecting mirrors of which the quantity is the same as that of the left reflecting mirrors; and a display screen is arranged at the right end of the central line of the optical platform in the light reflecting directions of six right reflecting mirrors.

Description

technical field [0001] The invention belongs to the technical field of optical measurement, and in particular relates to a detection device and a detection method for the consistency of the vibration isolation performance of a super-large-scale optical platform. Background technique [0002] Due to the continuous improvement of experimental instruments and production and processing precision, the requirements for working conditions are also getting higher and higher, and the optical table is one of the basic facilities to provide this condition. In recent years, the demand and use of ultra-large-scale optical platforms have become increasingly widespread, but due to their large size, the difficulty of their manufacture has increased significantly. Vibration isolation effect is one of the most important properties of an optical table. The structural design, material selection, manufacturing process, and deformation of the overall structure of the vibration isolation system du...

Problems solved by technology

At present, the vibration performance of the optical platform is generally measured by using a vibration spectrum analyzer for multi-point measurement, but the operation of this instrument is complicated and general laboratories and production units do not have it.
