Abstract
A light beam detector comprises a CCD module (3), a focusing lens (4), a half transparent and half reflective lens (2) and an optical screen (8), wherein the half transparent and half reflective lens (2) and the optical screen (8) are sequentially arranged in the direction of light transmission. The plane of the half transparent and half reflective lens (2) is disposed at a 45-degree angle with light. The plane of the optical screen (8) is vertical to a light beam, wherein one end of the optical screen (8) is connected with one end of the half transparent and half reflective lens (2). The light (1) is irradiated on the optical screen (8) through the half transparent and half reflective lens (2), reflected through the optical screen (8), then reflected through the half transparent and half reflective lens (2), and is focused on the CCD module (3) through the focusing lens (4). According to the light beam detector, the half transparent and half reflective lens is adopted to improve imaging sharpness and improve detection precision.
Description
Technical field
The utility model relates to a kind of beam detection instrument, is used for field of laser processing.
Background technology
Debuging at Photomechanical equipment often needs to detect the position of light beam and the shape of beam cross section in process, and the detection mode that adopts at present is by a plane mirror, the light beam imaging to be reflexed to the CCD module, as shown in Figure 1.After light beam 1 is spent mirror reflects through 45, through amasthenic lens 4, incide the CCD chip, CCD detection module 3 is converted to the signal of CCD chip output and is input to data processor 10 after digital signal and is further analyzed computing, and the image information display of the result that will calculate and collection is to display 9.
This detection mode is directly with the hot spot imaging, although detection speed is very fast, the hot spot imaging is unintelligible, and accuracy of detection is lower.
The utility model content
The utility model proposes a kind of beam detection instrument that utilizes semi-transparent semi-reflecting eyeglass imaging for the problems referred to above.Specific as follows:
Comprise: CCD module, amasthenic lens, set gradually semi-transparent semi-reflecting eyeglass, optical screen along the light transmition direction, the plane of semi-transparent semi-reflecting eyeglass and light are 45 degree to be placed, and the plane of optical screen is vertical with light beam, and an end of one end and semi-transparent semi-reflecting eyeglass joins; Light sees through semi-transparent semi-reflecting eyeglass and shines on optical screen, through after the reflection of optical screen, then through semi-transparent semi-reflecting eyeglass reflection, by amasthenic lens with convergence of rays on the CCD module.
Further, on optical screen with graduation.
Further, the CCD inside modules has the chip with CCD, and convergence of rays is to the CCD chip.
Further, has a CCD output interface on the CCD module.
Further, also comprise data line, data processor, display; The CCD output interface through data line, exports the light signal in the CCD module to the data processor computing, and the result of computing and the image information display of collection are to display.
The beneficial effects of the utility model are:
The detector that utilizes semi-transparent semi-reflecting eyeglass that the utility model proposes has improved imaging definition, improves accuracy of detection.

Embodiment
As shown in Figure 2, this beam detection instrument 0 comprises: semi-transparent semi-reflecting eyeglass 2, CCD module 3, amasthenic lens 4, optical screen 8.Has a CCD chip in CCD module 3.The plane of semi-transparent semi-reflecting eyeglass 2 and radiation direction are 45 degree angles, and light 1 sees through semi-transparent semi-reflecting eyeglass 2 and shines on optical screen 8, and through after the reflection of optical screen 8, light 5 is through semi-transparent semi-reflecting eyeglasses 2 reflections, by amasthenic lens 4 with convergence of rays to CCD chip 7.
Due on optical screen 8 with graduation, can without the computing of processor calculate can the artificial judgment light beam positional information.
