Exhibition.Traditional palm fingerprint instrument is directly made up of optical element group and picture receiver, only be can be only achieved image at normal temperatures and is adopted
The optimum efficiency of collection, can constantly it be deteriorated with the change image quality of temperature, even collection surface top layer fog is excessive to make
With；Such as the winter north is reduced due to environment temperature, fingerprint instrument prism temperature reduces, and human hand produces fog after restraining collection surface,
So that collection image effect reduction, even None- identified metacarpophalangeal line.With becoming clear day by day for problem, some solve environment temperature
The method of influence occurs in succession：Some palm print collection systems are not adhere to heating module on the surface of thang-kng in Collection prism, such as
" palm print instrument defogging system "（Application number 201020662394.4）Although such a system can effectively eliminate fog, need
The fixed mechanism of heating module is added, is fixed on prism outer circumference, adds system bulk, and in the precision optics of closing
The too high hidden danger of internal operating temperature in instrument and equipment be present.There is the optical glass of defrosting function need not increase system body for some
Product, but can not apply in palm fingerprint instrument application field：Such as " a kind of preparation method of electrically conducting and heating antifog glass "（Application number
99113595.4）, the conductive film layer of such a glass needs to adhere on a plastic film, causes inside glass refractive index disunity,
Because required precision of the optics palm fingerprint instrument to Collection prism angle is very high, making antifog glass by such a method can not ensure to slap
The IMAQ quality of fingerprint instrument；And for example " a kind of antifog glass preparation method using heating wire conductive exothermal "（Application number
99113594.6）, such a glass adds metal heat-conducting silk between needing in glass, even if metal heat-conducting silk can be made as described in it
It is transparent, also result in inside glass refractive index and differ, can not accurately control light path, more it cannot be guaranteed that the image of palm fingerprint instrument is adopted
Collect quality.
Utility model content
The technical problems to be solved in the utility model be to provide it is a kind of be applied to palm fingerprint instrument, do not influenceing original structure
Situation is issued to the self-heating temperature-controlling system of demisting purpose.
In order to solve the above-mentioned technical problem, palm fingerprint instrument self-heating temperature-controlling system of the present utility model mainly includes temperature control light
Learn element, temperature control electronic component, imaging optic element group, picture receiver；The temperature control optical element includes basalis, conduction
Film layer, protective layer, and the direct optical coating of conductive film layer is on basalis；Light is transmitted through to be controlled by temperature control electronic component
The temperature control optical element of temperature, then light path is corrected by imaging optic element group, it is ultimately imaged in picture receiver；This practicality is new
Type is inside temperature control optical element, on basalis, the conductive film layer of one layer of very thin printing opacity of direct plating, it is not necessary to it is solid to add other
Determine the material of conductive film layer, do not interfere with temperature control optical element inner refractive index；After switching on power, temperature control optical element is in temperature control
Under the control of electronic component in self-heating to certain temperature range；Due to temperature control optical element, particularly metacarpophalangeal line collection surface
Temperature is controlled in certain limit, so influence of the temperature change to image resolution ratio, non-ideal ring can be effectively eliminated
It can be imitated at a temperature of border and eliminate collection surface top layer fog, improve palm fingerprint instrument stability.
