に２次元的に微少変位することにより、光源の微少変位
を簡易な構成のもので高精度で実現できるものである。[1 Already Required] The present invention provides a star simulator that is equipped with a light source, a light source holder, and an optical system to simulate the light emitted by a star at an infinite distance, in which each light source holder is aligned with the optical axis of the optical system. By making a two-dimensional minute displacement within a plane orthogonal to the light source, minute displacement of the light source can be realized with a simple configuration and with high accuracy.
従来この種のスターシミュレータは、単−又はは複数の
星の光を模擬的に出力するが、いずれもその出力光の角
度方向は固定したものとなっていた。Conventionally, this type of star simulator outputs light from a single star or a plurality of stars in a simulated manner, but the angular direction of the output light is fixed in each case.
しかし、出力光の角度を変化したい場合にはスターシミ
ュレータ自体を回転させるかまたは出力光が照射される
被試験体を回転させることが必要である。However, if it is desired to change the angle of the output light, it is necessary to rotate the star simulator itself or rotate the test object to which the output light is irradiated.
被試験体を微小な角度で回転させるには、高精度で高価
な回転台を使用し、回転する軸をスターシミュレータの
光束の中で変位させなければならない困難がある。In order to rotate the test object through a minute angle, it is difficult to use a highly accurate and expensive rotating table and to displace the axis of rotation within the light beam of the star simulator.
またスターシミュレータ自体を高精度で微小な角度で回
転させることは、通常のスターシミュレータの重量が数
百ｋｇ程度であるので、非常に困難である。Furthermore, it is extremely difficult to rotate the star simulator itself with high precision at a minute angle because a normal star simulator weighs about several hundred kg.
本発明はこれらの困難性を解消して、光源の微小変位を
而易な構成で実現できるスターシミュレータを提供する
ことを目的とする。An object of the present invention is to solve these difficulties and provide a star simulator that can realize minute displacement of a light source with a simple configuration.

The light source holder is provided with a displacement means for independently slightly displacing the light source in two directions perpendicular to each other within a plane perpendicular to the optical axis of the optical system.

のものが得られる。The holder of each light source is slightly displaced two-dimensionally on a plane perpendicular to the optical axis. The distance of the optical axis from the light source to the measurement part is 1 to 2 m, and the length of minute displacement perpendicular to this is 1O
If it is in microns, its tangent (tan α)
The value of is about 10-6, and the change in angular direction is about 1 second.
