Optical network measuring device and measuring method for flying target

Abstract

The invention relates to an optical network measuring device and measuring method for a flying target. The measuring device comprises an optical network array generating module for forming orthogonalgrid light and a photoelectric conversion receiving array for receiving optical signals of a horizontal optical network and a vertical optical network in the orthogonal grid light respectively. In addition, the measuring method includes: an orientation and a size of a flying target are identified according shielding of an optical signal during orthogonal grid light passing by the flying target. During the measuring process, the flying target only shields the light instead of damaging the light and the flying target is not affected by the optical network, so that the repeatability of usage of the measuring device on occasions like a space-based platform is improved.

Description

technical field [0001] The invention relates to the technical field of measuring flying targets, in particular to an optical network measuring device and a measuring method for flying targets. Background technique [0002] At present, common methods for measuring the position and size of flying targets include optical imaging and radar detection. Not satisfactory. For example, for ultra-high-speed flying targets, if optical imaging is used to measure their position and size, a high-speed camera with ultra-high frame rate is required, otherwise the imaging will produce motion blur; especially for small targets of centimeter and millimeter levels, high-speed The camera has high image resolution. In this case, the optical imaging measurement method will generate a large amount of measurement data, which requires complex processing in the later stage. If the radar detection method is used to measure the same ultra-high-speed and small-sized flying target, there are also probl...

Problems solved by technology

[0003] At present, in order to meet the target position and size measurement requirements of space-based platforms and other places, a method for measuring the position and size of target impact points based on fiber grids is proposed, and there is also a low-power impact point based on wire grids. Information measurement device, the common point of these two methods is that every measurement of the target will destroy a part of the grid, which not only leads to the complete failure of the measurement function of the grid, but also causes certain damage to the flying target
