Foldable automatic temperature control optical axis calibrator target

Abstract

The invention discloses a foldable automatic temperature control optical axis calibrator target, which comprises a target surface, a target box, two foldable brackets and a temperature control box, wherein the target surface is a white canvas substrate coated with a black canvas pattern; a heating wire is buried in the interlayer between the black canvas and the while canvas; and a black area and a white area are respectively provided with a temperature sensing sensor. When in use, the target box is formed by butting two foldable rod groups and fixedly connected with the two foldable brackets which respectively spread out in place; and the heating wire and a lead wire of a temperature sensing device are both connected with the temperature control box. The calibrator target is suitable for parallelism calibration and accuracy test of an external field optical axis of a multi-axis optical system, accuracy test of an optical positioning and direction system or external field target test of a shooting system based on thermal-image collimation. The calibrator target has prominent advantages of simple structure, low cost, convenient carrying and is not restricted by field when in use.

Description

technical field [0001] The invention belongs to the technical field of calibration of weapon optical equipment, and mainly relates to a collapsible, automatic temperature-controlled optical axis calibration target, which is suitable for multi-axis optical systems, especially the external field optical axis parallelism of multi-axis optical systems with thermal imaging Calibration and its accuracy inspection, the accuracy inspection of the optical positioning and orientation system, or the field target test of the shooting system based on thermal image aiming. Background technique [0002] In the optical system for reconnaissance, tracking or fire control, it is generally equipped with optical observation systems such as optical direct sight, CCD imaging, and thermal imaging cameras. In order to achieve precise aiming and positioning of the target, the parallelism of all optical axes of the system must meet certain requirements. When calibrating and inspecting the optical ax...

However, the target frame of this scheme is small and the target surface is light and thin. If the year-on-year magnification is used as a large-size target surface, the target frame will be heavy under the condition of ensuring strength, and the wind resistance in the field is weak; Not suitable for thermal targets with heating wire inside and thick target surface
