Abstract
The invention discloses a universal large-aperture rigid bearing-type quick reflecting mirror, and relates to the technical field of precise optical mechanical structure design. The problems that an existing rigid bearing-type quick reflecting mirror cannot limit the Z-direction rotation freedom degree, miniaturization is difficult to achieve, and the universality is poor are solved. By means of the structural design that a universal ball bearing is combined with a flexible ring, rigid supporting can be provided for the large-aperture reflecting mirror, the two-dimensional rotation freedom degrees around the X axis and the Y axis can be provided, and the freedom degrees in the other directions are limited; a planar reflecting mirror is bonded with a reflecting mirror base through an optical epoxy adhesive, and therefore influences of the temperature, vibration and the like on the shape and the position of the reflecting mirror can be reduced; the reflecting mirror is driven in the mode that four linear voice coil motors conduct pushing and pulling two by two, the rotation moment is increased, and angle calculation is convenient; differential measuring is conducted by adopting four electric vortex sensors, the angle adjusting precision of a control system is improved; a driving assembly and a sensor assembly are symmetrically arranged in a staggered mode, and therefore the structural size of the system is decreased; an upper cover is universally installed, and therefore the quick reflecting mirror can be conveniently installed and used in various fields.
Description
technical field [0001] The invention relates to the technical field of precision optical mechanical structure design, in particular to a universal large-diameter rigid load-bearing fast reflector, which uses a universal ball bearing in the center, connects and supports it with flexible rings around it, and uses an eddy current sensor for angle feedback. Background technique [0002] The fast reflector is an important component for adjusting and stabilizing the boresight between the light source and the receiver. Relevant research institutes and units at home and abroad have conducted a lot of research on the fast reflector, and it has been successfully used in aerospace, marine and roadbed optoelectronics. in the device. [0003] At present, the structural forms of fast mirrors are mainly divided into two types: flexible shaft type and rigid bearing type. The flexible shaft structure has limited load capacity, and the rigid bearing structure can provide good support for lar...
