Described coated reflective mirror is 45 degree illuminators, and incident infrared light is turn 90 degrees and reflected, and the visible ray of incident is not changed to light path transmission.
Described tarsal glands infreared imaging device also includes desk-top support, is provided with the telecontrol equipment that can make apparatus main body part move up and down on desk-top support all around.
Described infrared illumination device includes two groups or more infrared light spot light source, and each infrared light spot light source is symmetrical according to the primary optical axis of tarsal glands reflects infrared light.
Described visible light illuminator includes two groups or more visible point of light light source, and each visible point of light light source is symmetrical according to the primary optical axis of tarsal glands reflects infrared light.
The utility model has the advantages that: tarsal glands infreared imaging device of the present utility model; adopted infrared illumination device; adopted infrared camera; again by computer and display; by be tarsal glands that strip distributes clear and intuitive show; can allow doctor that the form of tarsal glands and structure are observed, measured and pass judgment on, this has brought great help to tarsal glands dysfunction patient's diagnosis, treatment and prevention.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model will be further described:
Fig. 1 is the structural representation (side-looking) of this utility model embodiment mono-;
Fig. 2 is the structural representation (overlooking) of this utility model embodiment mono-;
Fig. 3 is the structural representation of this utility model embodiment bis-.
Wherein: 1 infrared illumination device; 2 visible light illuminator; 3 examinee's tarsal glandss; 4 coated reflective mirrors; 5 amasthenic lens; 6 infrared cameras; 7 microscopic examination devices; 8 shooting push buttons; 9 control handles; 10 primary optical axis; 11 focusing electro-optical devices.
The specific embodiment
Embodiment mono-: as shown in Figure 1 and Figure 2, an infreared imaging device, its apparatus main body partly comprisesinfrared illumination device 1,visible light illuminator 2, focusing electro-optical device 11, coatedreflective mirror 4,amasthenic lens 5,infrared camera 6,microscopic examination device 7.
Every group of infrared light spot light source (infrared light light beam) ofinfrared illumination device 1 can be comprised of one or more infrared light-emitting diodes.Angle between each infrared light light beam and primaryoptical axis 10 is 20～40 degree, is preferably 30 degree.The benefit of doing is like this to reduce the reflective impact of illumination light, makes the image taken more clear and have a third dimension.The wavelength of infrared light-emitting diode is 800～900nm, preferably 850nm.Selected like this benefit is that tarsal glands clear picture is bright, and video camera has enough sensitivity when this wavelength.
Each visible light beam ofvisible light illuminator 2 can be comprised of one or more visible light emitting diodes.Angle between each visible light beam and primaryoptical axis 10 is 20～40 degree, is preferably 35 degree.The benefit of doing is like this to reduce the reflective impact of illumination light, make that doctor observes image more clear and have third dimension.
The present embodiment has adopted two red semiconductor light emitting diodes to form focusing electro-optical device 11, is two dots while being irradiated to examinee'starsal glands 3, and these two focusing light coincide together when the predetermined distance apart from camera focus camera lens 5.Can make like this camerafocus camera lens 5 fixing consistent to the distance of examinee'starsal glands 3, the image that makes to take keeps clear and picture size maintenance is relative consistent, to doctor, carries out post analysis and judge provides convenience.
The focusing electro-optical device 11 of the present embodiment, is comprised of two red semiconductor light emitting diodes.Angle between each light beam and primaryoptical axis 10 is 20～40 degree, is preferably 25 degree.The benefit of doing is like this to determine easily the distance between video camera and photographic subjects.
Coatedreflective mirror 4 is 45 degree illuminators, and incident infrared light is turn 90 degrees to reflection, byamasthenic lens 5, entersinfrared camera 6.
Coatedreflective mirror 4 has to be had high luminescent properties and has low reflective performance at visible wavelength range when 800～900nm infrared wavelength.After having done like this, the infrared image of shooting is more clear, has effectively got rid of the interference of visible light part.
The tarsal glands infreared imaging device of the present embodiment also includes desk-top support, on desk-top support, be provided with the telecontrol equipment that can make apparatus main body part front and back move up and down, and thecontrol handgrip 9 of controlled motion device all around, upper inferior mechanical movement,control handgrip 9 upper ends and be provided withshooting push button 8, byshooting push button 8, controlinfrared camera 6 shooting operations.
