Abstract
The utility model relates to an improved infrared display device structure. The device is formed in a way that a liquid nitrogen groove which is arranged in a low temperature infrared camera is arranged on a material examining table of an infrared discriminator on the bases that the basic structure of the existing infrared discriminators is reserved. The utility model has the characteristics of good display effect, simple operation, etc.
Description
The utility model relates to the improvement of infrared display instrument structure.
On the article that extract the scene of a crime, often leave because of of long duration, seriously polluted disappear take off beyond all recognition mark and offender adopt smear, samples such as file that erasing or other means are forged, bill, for this class sample, mainly manifest extraction at present by infrared identifier or low temperature infrared photography technical method.Because above-mentioned sample vestige disappears sometimes and takes off more seriously, utilizing at present, infrared identifier both domestic and external manifests poor effect sometimes or can manifest at all.And that low temperature infrared photography technology manifests effect is obvious, has some drawbacks but compare with infrared identifier.It shows as: (1) must use special-purpose infrared film, and this film price is higher, and the term of validity is short, should not preserve for a long time; (2) strict to flushing environment of photo environment, photographic method and film etc.; (3), must select to be fit to the best band excitation source of this sample vestige material absorbing spectrum and the best band cutoff filter of emission spectrum at a certain sample.In actual applications, because objective condition is limit, this optical filter that is complementary with sample vestige material is difficult to accurately select, often by before the checker light source and receive that the optical filter of different wave length carries out the permutation and combination type test before the camera lens, but also after will treating film rinsing, could determine by the actual image effect of film.So loaded down with trivial details running program and bigger workload are difficult to full operation in real work.Be in the real work before light source and receive camera lens before only select the optical filter of fixing a certain common wavelengths, and this situation causes not matching of absorption spectrum and excitation-emission spectrum and vestige material sometimes, causing manifesting effect has the time difference, even has no the effect of manifesting; (4) low temperature infrared photography technology is a special extraordinary camera technique, and it is comparatively strict to finish the required condition of this work, and the professional and technical personnel that need have certain practical experience finishes.
The purpose of this utility model is exactly at the problems referred to above, provide a kind of easy and simple to handle, have a fine infrared display instrument that manifests effect.
The purpose of this utility model is achieved in that to be exactly on the basic structure basis that keeps existing infrared identifier, the liquid nitrogen tank in the low temperature infrared photography is arranged on the sample platform of infrared identifier, promptly constitutes this device.
Major advantage of the present utility model:
1, have and manifest effect well:
Because the utility model inspection part platform is provided with liquid nitrogen bath, inspection part in the liquid nitrogen tank, under low temperature (promptly at-196 ℃) condition, the irradiation that can improve blue green glow greatly excites down the infraluminescence efficient of sample, make under the normal temperature to be the inspection part vestige that infrared identifier manifested, and can be clear and legible in this device.
2, easy and simple to handle:
The utility model is to increase on keeping the basic structure basis of existing infrared identifier that liquid nitrogen tank is arranged (is that the low temperature infrared photography is provided with except that liquid nitrogen tank, all the other members are identical substantially with infrared identifier), therefore the structure of infrared identifier, easy and simple to handle is also had by this device.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is a sample supporting plate front view;
Fig. 4 is the vertical view of Fig. 3;
Fig. 5 is the vertical view of the horizontal adjustable bracket among Fig. 1;
Fig. 6 is the vertical view of the vertical adjustable bracket among Fig. 1.
Below in conjunction with accompanying drawing concrete structure of the present utility model is described further:
The utility model comprises body 18, body 18 is provided with takes the photograph phase case 8, light-source box 11, display 14, incandescent lamp 4, the side of taking the photograph phase case 8 is for receiving optical filter 10, its structural feature be the liquid nitrogen tank 5 of light hole 12 belows of cavity 15 of body 18 by lateral bracket 2, vertically carriage 1 is fixed in the body 18, is provided with sample supporting plate 7 in the liquid nitrogen tank 5.
The bottom of liquid nitrogen tank 5, side are respectively arranged with thermofin 6, so that the time that liquid nitrogen keeps is continued.
The bottom of cavity 15 is provided with shadow shield 16, and the cavity 15 of shadow shield 16 belows is provided with air hole 17.
Convenient for fetching and delivering sample, can be provided with button fly front 19 in the front of the cavity 15 of body 18.
Be respectively arranged with horizon equipment 13, adjustable support 3 outside the cavity 15, so that the liquid level of liquid nitrogen keeps level.
Receive optical filter 10 and can be arranged in the rotatable round box body, with turn-knob 19 its rotations of control.
Narrate a course of action of the present utility model below:
Open button fly front 19, pull out outside the cavity 15, sample is placed in the pressing plate 25, and then push liquid nitrogen tank 5 to original position, close button fly front 199 by will substitute the bad for the good the liquid nitrogen tank 5 of liquid nitrogen of the handle 20 of liquid nitrogen tank 5; The blue streak that the blue streak lamps send in the light-source box 11 through light hole 12 to sample, the infrared light that is excited on the sample through light hole 12, reflective mirror, reception optical filter 10, take the photograph the lens imaging in the phase case 8, by infrared camera image transitions is become visual picture again, show by display 14 again, on display 14 if do not demonstrate the vestige of detected pieces, or when unintelligible, rotatable knob 9, by selecting to receive optical filter 10 accordingly, make display trace clear till.
