Embodiment Construction

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between various components under a certain posture (as shown in the accompanying drawings). The relative positional relationship, the movement situation, etc., if the specific posture changes, the directional indication also changes accordingly. ...

Abstract

The invention belongs to the field of fast reflectors, and discloses a flexible support-based reaction-force-free fast reflector, which comprises a plane reflector assembly, a flexible support assembly, a sensor assembly, an actuator, a reaction plate and a base, the flexible support assembly comprises an upper flexible support and a lower flexible support, and the plane mirror assembly is connected with the base through the upper flexible support; the reaction plate is connected with the other side of the base through a lower flexible support; the number of the sensor assemblies and the number of the actuators are both four, the sensor assemblies and the actuators are evenly distributed on the plane mirror assembly in a staggered mode, one ends of the sensor assemblies are connected with the plane mirror assembly, the other ends of the sensor assemblies are connected with the base, one ends of the actuators are connected with the plane mirror assembly, and the other ends of the actuators are connected with the reaction plate. According to the fast reflecting mirror, the counter-acting force of the fast reflecting mirror is eliminated, the influence of the motion of the fast reflecting mirror on the base is greatly reduced, and the performance of the whole system is improved.

Description

technical field [0001] The invention relates to the field of fast reflecting mirrors, in particular to a fast reflecting mirror without reaction force based on flexible support. Background technique [0002] The fast launch mirror is an optical device developed in recent years for high-precision beam control. It can ensure high-precision inertial pointing accuracy in a wide bandwidth range. It can be used in astronomical telescopes, precision tracking and aiming, long-distance detection, Laser communication, laser weapons and other fields. [0003] Fast mirror systems usually use a flexible structure to provide support, which can achieve frictionless and fast response. Flexible support is to use elastic material or through a certain shape design to achieve the characteristics of low stiffness in the working direction and high stiffness in the non-working direction. The flexible support has the advantages of no wear, smooth movement, no need for lubrication, wide operating ...
