(57) [Summary] An object of the present invention is to realize a small angle measurement error measuring device that can easily avoid the occurrence of a measurement error due to a parallax between a visible light angle measuring device and a specimen. A mirror (6) reflects a light beam emitted by a beam combiner (5) in an arbitrary direction with respect to rotation and elevation and guides it to a half mirror group (7), and the half mirror group (7) transmits and reflects the light beam to a specimen position. The mirror 8 guides the light beam to the position of the sample under test, so that the parallax between the visible light angle measuring device and the sample can be obtained simply by adjusting the detection position coarse enough to detect the light beam. A small angle measurement error measuring device that easily avoids the occurrence of a measurement error due to the measurement is realized.

Therefore, it is desired to calibrate the angle measurement value by measuring the error included in the angle measurement value, which is the measured value, to grasp the accuracy.

To do. The visible light angle measuring device 3 is typified by a theodolite and is separately installed at the position of the sample, and is adjusted in the turning direction and the elevation angle direction by using the visible image of the visible light emitted from the visible light source 2. , The individual light ray angles and the angle differences are measured by directing the light sources in the directions of the plurality of visible light sources 2.

することが困難であった。In the conventional angle measuring accuracy measuring device, the same number of light sources 1 and visible light sources 2 for the sample as the number of angle measuring are equal to or more than the focusing distance of the optical sensor as the sample. It is difficult to realize a small angle measuring accuracy measuring device because they are installed in a space separated from each other. Further, it has means for compensating for the detection height and the translational position difference between when the optical sensor and the visible ray angle measuring device 3 are installed and keeping them at the same position. A large amount of time is required to reproduce the light source detection position of the device 3, and equipment for position compensation is required, which causes a measurement error due to the parallax between the visible light angle measuring device 3 and the optical sensor. It was difficult to avoid that.
