Being described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of same or like function from start to finish. The embodiment described below with reference to accompanying drawing is illustrative of, and is only used for explaining the present invention, and is not considered as limiting the invention.
In describing the invention, it will be appreciated that, orientation or the position relationship of the instruction such as term " " center ", " on ", D score, "front", "rear", "left", "right", " vertically ", " level ", " top ", " end " " interior ", " outward " be based on orientation shown in the drawings or position relationship; be for only for ease of the description present invention and simplifying and describe; rather than instruction or imply indication device or element must have specific orientation, with specific azimuth configuration and operation, be therefore not considered as limiting the invention.
In describing the invention, it is necessary to explanation, unless otherwise clearly defined and limited, term " installation ", " being connected ", " setting " should be interpreted broadly, for instance, it is possible to it is be fixedly linked, arrange, can also be removably connect, arrange, or connect integratedly, arrange. For the ordinary skill in the art, it is possible to concrete condition understands above-mentioned term concrete meaning in the present invention.
Embodiment one
As it is shown in figure 1, the present invention provides a kind of laser energy detection device, including:
(1) energy receiver, including housing 1, diffuse-reflectance layer 2, incident light hole 3, light perforation hole 4, described housing 1 is in spherical, described diffuse-reflectance layer 2 is arranged in described housing 1, the material of described diffuse-reflectance layer is plastics, described incident light hole 3, light perforation hole 4 run through described diffuse-reflectance layer 2, housing 1, and described incident light hole 3 is one, and described smooth perforation hole 4 is 4;
(2) energy meter 5, described energy is calculated as 4, described energy meter and described smooth perforation hole one_to_one corresponding, and described energy meter is arranged in described smooth perforation hole.
The operation principle of a kind of laser energy provided by the invention detection device is: laser energy enters in housing by incident light hole, then carrying out diffuse-reflectance through diffuse-reflectance layer makes laser energy be uniformly distributed on the inwall of spherical shell, then passes through light perforation hole and is mapped in energy meter.
If the energy detection receptor area of energy meter is S1, the inner face area of diffuse-reflectance layer is S, then the laser energy Jc when laser energy Jd that energy meter receives and incidence just has a proportionate relationship Jd=Jc*S1/S. From a little, the energy that energy meter receives is weak, and the laser energy after weak makes it possible to gauge and is hardly damaged.
Shell is spherical so that enters the laser energy in housing dispersedly evenly, is provided with four energy meters, the laser energy size of four energy meter detections is identical, if one of them energy meter is impaired, other several energy meters still can detect laser energy, thus ensureing the normal operation of equipment.
Diffuse-reflectance layer adopts plastic material that diffuse-reflectance layer is conveniently firmly placed in housing.
Further, the thickness less than described housing 1 of the degree of depth in described smooth perforation hole 4 is inserted in described energy meter 5. So neither affect laser energy in housing, carry out diffuse-reflectance, do not affect again the laser energy after diffuse-reflectance and penetrate from light perforation hole.
Further, the light line of incidence that the straight line that described incident light hole 3 and arbitrary described smooth perforation hole 4 are formed and the light beam incident direction in described incident light hole 3 are formed does not coincide. The result of detection so preventing energy meter is inaccurate.
Embodiment two
As in figure 2 it is shown, the present invention also provides for another kind of laser energy detection device, including:
(1) energy receiver, including housing 1, diffuse-reflectance layer 2, incident light hole 3, light perforation hole 4, described diffuse-reflectance layer 2 is arranged in described housing 1, described incident light hole 3, light perforation hole 4 run through described diffuse-reflectance layer 2, housing 1, described incident light hole 3 is one, and described smooth perforation hole 4 is 4;
(2) energy meter 5, described energy is calculated as 4, described energy meter and described smooth perforation hole one_to_one corresponding, and described energy meter 5 is arranged at the aperture place of described smooth perforation hole 4.
Energy meter is arranged on the aperture place of light perforation hole, is more beneficial for laser energy and penetrates from light perforation hole after diffuse-reflectance fully.
Embodiment three
As it is shown on figure 3, the present invention provides again a kind of laser energy detection device, including:
(1) energy receiver, including housing 1, diffuse-reflectance layer 2, incident light hole 3, light perforation hole 4, described diffuse-reflectance layer is arranged in described housing, and described incident light hole, light perforation hole run through described diffuse-reflectance layer, housing, described incident light hole is one, and described smooth perforation hole is 4;
