Embodiment Construction

[0036] The embodiment of the invention discloses a fast reflector, which uses a cross spring bearing to support the reflector base, and when used in conjunction with a driver, not only improves the deflection angle of the working mirror body on the reflector base, but also improves the rotation accuracy of the working mirror body.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0038] see Figure 1-Figure 7 , the embodiment of the present invention provides a fast reflector, which includes a base 9, a wor...

Abstract

The invention discloses a fast reflection mirror, comprising a base, a working mirror body, cross spring bearings and a driver; the working mirror body is assembled on a reflection mirror seat; two cross spring bearings constitute one group, there are totally two groups, wherein the axes of the two cross spring bearings in the first group of cross spring bearings coincide with a first straight line, and the axes of the two cross spring bearings in the second group of cross spring bearings coincide with a second straight line; the first straight line and the second straight line are perpendicular to each other and intersected at an origin; each cross spring bearing is connected to the reflection mirror seat and the base respectively; and the driver is used for driving the reflection mirrorseat to rotate within a preset angle range around the first straight line and / or the second straight line. According to the fast reflection mirror, the cross spring bearings support the reflection mirror seat, the cross spring bearings have the advantages of large deflection range and high rotating precision, and when the cross spring bearings are used with the driver, the deflection angle and therotating precision of the working mirror body can be improved, so that the fast reflection mirror is applicable in the fields of precision machinery, precision measuring instruments, medical equipment and the like.

Description

technical field [0001] The invention relates to the technical field of precision optical mechanical structure design, and more specifically relates to a fast reflector. Background technique [0002] With its advantages of high precision, high bandwidth, and high resolution, fast mirrors have become a key part of stabilizing and correcting beams in optical systems. Especially in space optical communications, fast mirrors are used in capture, aiming and tracking systems. Ensure that the laser communication link works normally. [0003] The fast mirror includes a base, a working mirror body, a flexible support, a driver, a position detection element and a controller. The flexible support plays the role of a fulcrum and limits the translational freedom of the working mirror body in all directions, so that the working mirror body has only The degree of freedom of rotation around two working axes; when the light beam incident on the working mirror body is deflected at a certain a...
