Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in Figure 1, provide the structural representation of the hand-held zoom thermal imaging system of an embodiment of the utility model, comprised infrared zooming lens 1, thermal imaging detector 2, control module 3, display module 4, eyepiece 5, power module 6.
Outside scenery carries out imaging by infrared zooming lens 1 and thermal imaging detector 2, and output packet is containing the analog video signal of Infrared Targets information.
Owing to being portable equipment, therefore, can use manual control machinery is controlled in other words zoom, compensation adjustment, as the zoom cam mechanism is adjusted, about the zoom cam, those skilled in the art should have clearly understanding.
After the character information of control module 3 stack correlation behaviors, output to display module 4, for driving micro-display screen, by eyepiece 5, can realize the real-time monitored to present image.
The normal voltage that the function of power module 6 is is the regulation grade by the externally fed voltage transitions, and carry out after voltage stabilizing outputing to each sub-module and powered, the normal steady operation such as thermal imaging detector 2, control module 3, display module 4 guaranteed.
In Fig. 1, peripheral black surround means shell, for integration and the protection of each function element.
The optical system diagram that Fig. 2 a-Fig. 2 c is a kind of hand-held zoom thermal imaging system, focal length is 25-75mm, service band is 8-12um, by 4 eyeglasses, formed, be followed successively by from front to back front fixedly group 101, zoom group 102, compensation group 103 and rear fixedly group 104, wherein, fixing group 101 is the fixing positive meniscus lenss of a slice, for the target to different distance, is focused on; Zoom group 102 is movably double-concave negative lens of a slice, for changing the focal length of system; Compensation group 103 is movably convex-concave positive lenss of a slice, and the one side of close thing side is provided with system stop, for the skew of bucking-out system zoom process image planes position; Rear fixing group 104 is a slice positive meniscus lens, can move forward and backward, so that different object focus is clear to distance, and can in the uniform temperature variation range, compensate the out of focus of image planes.
Infrared zooming lens can change the system focal length within the specific limits, can reach large visual field search target, and small field of view examines the purpose of target.When infrared zoom lens changes from wide-angle side to long burnt end, distance between front fixing group 101 and zoom group 102 increases always, distance between zoom group 102 and compensation group 103 reduces always, and the distance between compensation group 103 and rear fixedly group 104 first reduces rear increase.
Only have 4 lens in said structure, all adopt germanium material, compact conformation and be easy to make processing, only adopt a slice aspheric surface, effectively reduced production cost.
The F number of zoom lens is 1.0, so relative aperture is larger, has increased light-inletting quantity, has improved image contrast.
