Embodiment Construction
[0028] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.
[0029] like figure 1 Shown is the solar simulator layout diagram of the present invention. The solar simulator can be regarded as converging the light emitted by the light source 4 at the integrator mirror 3, and the integrator mirror plays a uniform role, and the integrator mirror 3 can be regarded as a uniform point light source, and the light emitted by the point light source passes through the collimator mirror and the target state becomes for parallel light. The angle between the optical axis bef...

Abstract
The invention provides an adjusting device for a splicing collimating mirror for an off-axis solar simulator. The adjusting device comprises a spherical collimating mirror with a spherical radius R, alaser, an adjustment plate and a light screen, wherein the laser is located at the center of the spherical collimating mirror, the light screen is located at the position of the laser, the sphericalcollimating mirror is spliced by a plurality of hexagonal spherical unit mirrors, the rears sides of the hexagonal spherical unit mirrors are respectively provided with axial adjustment mechanisms, swing adjustment mechanisms and pitch adjustment mechanisms, the adjustment plate is located between the spherical collimating mirror and the laser, the distance between the laser and the adjustment plate is 1 / 10 of the spherical radius R, the adjustment plate is provided with round holes with the same number as the hexagonal spherical unit mirrors, the center of each round hole corresponds to thatof the corresponding hexagonal spherical unit mirrors, and the diameter of the round holes is 1 / 10 of the diameter of the inscribed circle of the hexagonal spherical unit mirrors. The adjusting methodfor a splicing collimating mirror for an off-axis solar simulator is a simple method using self-calibration of the spherical center, and the adjusting device has a simple design and is easy to implement.
Description
technical field [0001] The invention relates to the technical field of space environment ground simulation, in particular to an adjustment device and an adjustment method for splicing collimating mirrors for off-axis solar simulators. Background technique [0002] A solar simulator is a test or calibration device that simulates the light radiation characteristics of the sun under different atmospheric quality conditions indoors. It is mostly used for environmental simulation tests of space vehicles, and can provide space vehicles with uniform, collimated and stable solar radiation that matches the solar spectral distribution. [0003] With the development of large-caliber high-precision remote sensors, it is necessary to accurately simulate the space environment on the ground. Due to the limitation of the processing size, the collimator mirrors of large and medium-sized solar simulators generally adopt the splicing type, that is, they are spliced by multiple small lenses. ...
