Thermal imaging system optical system is divided kind by visual field, generally can be divided into monoscopic thermal imaging system, many visual fields thermal imaging system (interruption zoom), continuous zoom thermal imaging system.Be interrupted zoom thermal imaging system and there is multiple observations visual field, can take into account to a certain extent far away, in, the observation of close-in target, but there is frame losing in zoom process, lose the problems such as object observing, be difficult to meet the specific needs of observing; And continuous zoom thermal imaging system can keep the continuity of image in the transfer process of visual field, it is clear that target image can remain, can lose objects when multiplying power changes, and be that imaging system solves the optimal selection that large visual field search small field of view is differentiated.
Refrigeration-type thermal imaging system is a kind of thermal imaging system the most responsive to the tiny temperature contrast in scene.They can detect temperature contrast the most tiny between object.This thermal imaging system can medium-wave infrared in other words the medium-wave infrared wave band in spectrum carry out imaging, and the hot contrast height of this wave band depends on black matrix physics.Hot contrast is to be changed and the signal intensity that causes by target temperature.Hot contrast is higher, just more easily detects the target not too large with ambient temperature difference.
Due to large 3 orders of magnitude of the relative white light glass material of dn/dt value of infrared optical material, the variation of environment temperature has very serious impact to infrared system, makes image planes drift, and picture element variation, even can not be used.Existing refrigerated thermal imager adopts the version of motor driving device cam to realize anamorphosis function, but the error that mechanical cam brings is much larger than the precision of stepper motor, and in use observing effect is far worse than the mode that adopts two motors to drive respectively two constituent elements.
Therefore, in two constituent element zooming systems, adopt two motors to drive respectively the mode of two constituent elements, and do not adopt the form of mechanical cam, can realize easily heat focusing function by the relative motion of two motors like this, and because the precision of stepper motor is very high, all energy is accomplished for the functions such as the focusing of optical system, zoom, heat focusing, and effect is fine.
Summary of the invention
To be solved in the utility model is exactly the large shortcoming of existing refrigerated thermal imager error, and a kind of continuous zoom medium wave refrigeration mode thermal imaging system is provided.
