Abstract

The invention relates to a telescopic sleeve type camera mechanism and provides a space-based telescopic sleeve type binary optical camera mechanism to solve the problems that an existing space optical camera is large in weight and hard to stretch and retract repeatedly, and the photographing light path can be blocked easily in the using process. According to the space-based telescopic sleeve type binary optical camera mechanism, a first telescopic sleeve, a second telescopic sleeve, at least one third telescopic sleeve and a fixed sleeve are connected through a plurality of locking devices from top to bottom in sequence to form a camera lens cone; the outer diameter of the first telescopic sleeve is smaller than that of the second telescopic sleeve; the outer diameter of the second telescopic sleeve is smaller than that of the third telescopic sleeves; a main camera lens is arranged on the top of the first telescopic sleeve; a driving sleeve is sleeved with the fixed sleeve; the bottom of the fixed sleeve is provided with a base; a bottom-end receiving lens is arranged on the base and located at the center of the camera lens cone; a bearing supporting system is located between the driving sleeve and the fixed sleeve; a stepping motor is connected with the driving sleeve through a gear transmission mechanism. The space-based telescopic sleeve type binary optical camera mechanism is applied to the field of spaceflight optical remote sensing.

Description

technical field [0001] The invention specifically relates to a space expandable sleeve type binary optical camera mechanism. Background technique [0002] Binary optics is a new branch of optics developed based on the theory of light wave diffraction. It is a frontier discipline formed by the mutual penetration and intersection of optics and microelectronics technology. Binary optical devices, also known as diffractive optical devices, have the advantages of small size, light weight, easy replication, low cost, high diffraction efficiency, many degrees of design freedom, wide choice of materials, and unique dispersion properties. In many fields such as optical fiber communication, image processing, biomedicine, national defense and military affairs, it is showing an unprecedented important role and broad application prospects. Applying binary optics technology to aerospace optical remote sensing system helps to reduce the volume and weight of the system, reduce the cost of ...
