Abstract
The utility model relates to the field of optical imaging, in particular to a coherent light source. Light source equipment of the coherent light source comprises a reflective bowl, a light source component, a lens component and a grating rotating component which are positioned in the horizontal direction and arranged from left to right. Light emitted by the light source is intensified after being reflected by the reflective bowl; then divergent beams are changed into convergent beams by a collector lens; all convergent spots of the plurality of convergent beams light the section of a sample and arouse the section to reflect light; and light reflected by the sample is imaged on a plane through a front lens and a rear lens. A transmission ball screw is connected with a supporting seat through a bearing; and the lens component is fixed on the supporting seat. For the coherent light source, the lead screw is controlled electrically to move so as to drive the lens on the supporting seat to move horizontally, the effect for eliminating stray lights is good, and the requirements on field or resolution ratio can be met.
Description
Technical field
The utility model relates to optical imaging field, particularly a kind of coherent source.
Background technology
Three-dimensional imaging and measuring system are known, and be general in order to obtain the 3D shape of object, is the 3D shape of its physical size ideally.Such imaging and measuring system are divided into two classes basically: 1) surface-contact system: 2) optical system.Optical system further is divided into laser triangulation again, structured lighting, and the More interferes, different systems such as three-dimensional imaging and travel-time measurement.
The method that the More interferes is accurate, but expensive and consuming time: the method for three-dimensional imaging need to two cameras or the image of obtaining that carries out taking pictures for twice compare, obtain the three-dimensional surface of object; Travel-time mensuration Laser Measurement is from the time of the relevant every point reflection of object, and it needs expensive laser scanning transmitter and receiver.
Coherent source of the prior art is usually accurate inadequately, or needs expensive equipment, or need obtain satisfactory accuracy by multiexposure, multiple exposure.Therefore just need development a kind of not only accurate but also be easy to use and not really expensive coherent source.
Summary of the invention
The technical problems to be solved in the utility model provides that a kind of not only accurately but also be easy to use and be not very expensive coherent source this coherent source is not only simple in structure, with low cost, and each lens position is adjustable, and it is effective to eliminate parasitic light.
For solving the problems of the technologies described above, described coherent source mainly comprises light source and drive apparatus, it is characterized in that: described light source comprises reflector, light source part, lenticular unit and the grating rotating parts that are positioned on the horizontal direction from left to right; Left end at described reflector is provided with a fan that is used to dispel the heat; Described drive apparatus is arranged on the lower end of described light source, mainly is made up of servomotor and transmission ball screw, and the transmission ball screw is connected with a supporting base by bearing, and described lenticular unit is fixed on this supporting base.
Described grating rotating parts are connected with an angle potentiometer and a CD-ROM drive motor.
Right-hand member at described light source is connected with a bellows camera lens, and described bellows camera lens and described reflector, light source part, lenticular unit and grating rotating parts are positioned on the same horizontal direction.
Described light source part is 35 watts a xenon lamp.
Compared with prior art, the light source of the utility model coherent source comprises reflector, light source part, lenticular unit and the grating rotating parts that are positioned on the horizontal direction from left to right.The light that light source sends is for conversion into convergent beam through collector lens with divergent beams then through reflector reflection back light grow, and all of a plurality of convergent beams are assembled luminous point illumination sample in cross section, and excite this sectional reflective.The sample reflected light is through front lens and rear lens imaging in the plane.The transmission ball screw is connected with a supporting base by bearing, and described lenticular unit is fixed on this supporting base.The utility model moves by the electrical control screw mandrel, thereby drives the lens move left and right on the supporting base, and it is effective to eliminate parasitic light, and the coherent source that satisfies visual field or resolution requirement can be provided.
