され標準的な計測値が得られない。 However, in recent years, it has become possible to perform aiming using other devices, such as night vision equipment, and do not rely on the aiming optical system of the laser irradiation device. It has become necessary to measure the boresight error of This measurement is possible by actually irradiating the laser beam, but compared to the method of measuring the boresight error of the laser irradiation device described above, it requires a somewhat longer distance and is therefore more extensive. Also, it is not possible to obtain standard measured values because it depends on the performance of other devices used for aiming.

なお、８は嵌合ピンである。 FIG. 1 is a side view when measuring the amount of deviation of the aiming line of the aiming light receiving system of the laser irradiation device with respect to the mounting reference line (or reference plane) of the laser irradiation device according to an embodiment of the present invention. In the figure, 1 is an autocollimator, 2 is a reference mirror, 3 is a laser irradiation device to be measured, 7 is its aiming optical system, and 6 is its mounting reference surface. Further, 4 is an optical bench, and by placing the laser irradiation device 3 on this bench, the mounting reference surface 6 of the irradiation device 3 is replaced with the reference surface 5 of the optical bench, and the reference mirror 2 is placed on the laser optical axis. The optical bench 3 is fixed at a predetermined location on the optical bench 3 and is made of a glass plate or the like that reflects a part of the input light from the autocollimator 1, and is replaced so as to be suitable for measurement by the autocollimator 1.

けるボアサイト誤差θが次式により求まる。 In this case, when the crosshair of the autocollimator 1 is adjusted and aligned with the reticle of the aiming optical system 7 of the laser irradiation device 3, the amount of deviation between the optical axis of the autocollimator 1 and the light reflected from the autocollimator 1 by the reference mirror 2 If θ 1 is read with autocollimator 1,
This becomes the amount of deviation in parallelism between the sight line of the sighting optical system 7 and the mounting reference surface 6 of the laser irradiation device 3. From this, if we subtract the amount of deviation in parallelism between the aiming line of the aiming optical system 7 of the laser irradiation device 3 and the laser beam, that is, the bore side error θ 2 , we can calculate the difference between the laser irradiation device 3 and other aiming devices. The boresight error θ in the laser irradiation device 3, which is the boresight error when operated with a line-of-sight device, is determined by the following equation.
θ＝θ1−θ2
