Vibration mirror-based high-speed virtual camera system, observation method and equipment

Abstract

The invention belongs to the field of imaging, and in particular relates to a vibrating mirror-based high-speed virtual camera system, observation method and equipment, aiming to solve the problem that the prior art cannot observe multiple objects in real time at a long distance with high definition. The system of the present invention includes: a computer, used to obtain the position to be observed on the set observation plane; D\A signal converter, used to convert the received digital signal into an analog signal; the vibrating mirror control board, used to convert the received Analyze the analog signal of the scanning electron microscope into a control command; the vibrating mirror unit is used to control the rotation of the lens of the scanning electron microscope according to the control command, obtain the optical signal of the position to be observed, and reflect it; the high-speed camera is used to reflect the optical signal of the scanning electron microscope Take pictures, obtain high-definition images of the positions to be observed on the set observation plane, and send them to the computer. The invention can realize real-time and high-definition shooting of multiple distant targets.

Description

technical field [0001] The invention belongs to the field of imaging, and in particular relates to a vibrating mirror-based high-speed virtual camera system, observation method and device. Background technique [0002] In the process of shooting long-distance objects, due to the limitation of the focal length of ordinary cameras, short-focus cameras can obtain a larger field of view, usually with a viewing angle of more than 60 degrees, but cannot describe detailed information, and it is blurry when shooting long-distance images; telephoto cameras It is clearer and retains more details when shooting distant objects, but the field of view is narrow, usually within 15 degrees, and only small-scale scene observation can be performed. [0003] In order to shoot a large range of long-distance objects with high definition, two methods are mainly used at present. One is to arrange a large number of telephoto cameras in an orderly manner to form a camera array. In the later stage, ...
