Problems solved by technology

[0008] However, there are shortcomings in this scheme: in order to realize the 360-degree rotation of the spiral arm, this scheme requires a large circular experimental space, and a dedicated large-area laboratory needs to be established.
Although the central manipulator can realize the three-axis attitude control of the target, its load-bearing capacity is small, the attitude angle accuracy is low, and the stability of the center point is insufficient.
In addition, for the measurement of large-scale targets, it is necessary to use a large-caliber solar simulation light source, which is too large to be installed and used on the spiral arm, so this solution is still only suitable for low-precision analog measurement of the optical properties of small-sized space debris

Abstract

The invention provides an indoor simulation device for space target optical characteristic actual measurement conditions. The indoor simulation device for the space target optical characteristic actual measurement conditions comprises a light source (1), a reflecting mirror (2), a three-axle table (3), a detector (4), a detector guide rail (5), a space target model (6) and a detector support (7). According to the indoor simulation device for the space target optical characteristic actual measurement conditions, optical characteristic measurement of a high angle precision and large-size space target model in any postures and under any illumination angles is simply achieved through small space due to a craft design, especially a four-axis system which is formed by the three-axle table and a single-axis rotary detector support.

Description

technical field [0001] The invention belongs to the field of optical characteristic measurement of space objects, and in particular relates to an indoor simulation device for actual measurement conditions of optical characteristics of space objects. Background technique [0002] The indoor simulation technology of the optical characteristics of space targets uses equipment and methods to simulate the space lighting conditions faced by space targets in the laboratory, and at the same time simulates the relative geometric relationship between the light source-target-detector. The purpose is to realize the actual observation process (ground-based telescope observation , space-based payload observations) and parallel simulation of observation data. Using laboratory simulation, it can assist in the establishment of various theoretical models of the target optical properties, and can compare the actual observation data to study the influence of various factors such as target shape...
