Embodiment
Invisible laser apparatus 1 comprises infrared laser and ultraviolet laser, below for 1064nm infrared laser, introduces the principle of the present invention.
The present invention utilizes in space determine the principle of a straight line at 2, instruction laser is regulated to make its all identical two point in space with infrared laser, to reach the object that instruction light overlaps with infrared light, therefore should be able to observe infrared laser and space two point of instruction light process when adjustment light path simultaneously.
As depicted in figs. 1 and 2, additional visible ray indicating unit comprises indication laser 3, turns mirror 5 and window of tube 9, the described mirror 5 that turns is made by the material of invisible laser height transmission, and can rotate around center of lens axis, turning mirror 5 is that fan-shaped summit is divided into three sector regions taking center of lens, it is respectively phosphor region 51, echo area 52 and transmission area 53, described phosphor region 51 is provided with the fluorescent material that invisible laser can excite, described echo area 52 is provided with the high reverse--bias material to visible instruction laser, and described transmission area 53 keeps lens materials not process. Turning mirror 5 is arranged in the light path of invisible laser apparatus 1, and the opposite direction of indication laser 3 never visible laser 1 is incident to the back side turning mirror 5, and after turning the reflection of mirror 5 echo area 52, exposes to window of tube 9 with invisible laser apparatus 1 coaxial line. Fluorescent substance is er-doped LiYF4 or er-doped Ga2S:La2O3 up-conversion luminescent material. Center of lens is connected with the rotating shaft of motor 6, and motor 6 is connected with displacement platform 7 by pole, and displacement platform 7 can meet two-dimension translational and rotate the function regulated.
In test, lens device can stablize rotation, and when the phosphor region 51 of eyeglass is in light path, the upper conversion function due to fluorescent substance and the diffuse-reflectance to visible instruction laser, eyeglass can show infrared laser hot spot A point and visible instruction laser facula C point simultaneously. When the echo area 52 of eyeglass is in light path, infrared laser is blocked, and naked eyes can be observed instruction laser as seen and be reflected on window of tube and leave hot spot D point. When being in light path through district 53 of eyeglass, infrared laser is directly radiated on window of tube, and the fluorescence mass-energy on window of tube demonstrates hot spot B point. When the rotating speed of eyeglass enough fast (be greater than 8 turn/second), the space hot spot being observed visually is a result to time integral, can observe 4 points (A point, B point, C point and D point) in the space of infrared laser and visible instruction laser process simultaneously. As long as regulating the visible incident direction of instruction laser light beam and the attitude of lens device, 2, the space of infrared laser and visible instruction laser process is overlapped respectively, and (A point and C point overlap, B point and D point overlap), so that it may realize to the object of the additional instruction light of infrared laser.
Hereafter, stop eyeglass and rotate, make the echo area 52 of eyeglass be in light path, the light path of visible instruction laser can be utilized to show the light path of infrared laser, facilitate design and the control of subsequent optical path. After completing light path design, rotate eyeglass so that it is transmission area 53 is in light path, can use infrared laser normally.
