Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the accompanying drawings and be embodied as This utility model is described in detail by example.
Embodiment one: as it is shown in figure 1, a kind of portable trace explosive photo-sensitive cell, including photo-sensitive cell 1, absorption-type filter Mating plate 2, collection mirror 3, observation window 4, high molecular film substrate 5, laser diode 6, air pump 7, heater 8, cleaning sampling sheet 9, housing 20, described photo-sensitive cell 1, absorption-type optical filter 2, collection mirror 3, observation window 4, high molecular film substrate 5, laser two pole It is internal that pipe 6 is installed on described housing 20, and described observation window 4, high molecular film substrate 5 surround air cavity 10, described heater 8, Described air pump 7 is respectively communicated with in the outside of described housing 20 and the both sides that are positioned at described air cavity 10, and described cleaning sampling sheet 9 is vertical It is inserted in the draw-in groove of described heater 8;Described photo-sensitive cell 1 connects alarming horn 12 and touch screen 13 by single-chip microcomputer 11; Described laser diode 6 arranged parallel is in the lower section of described high molecular film substrate 5, and described photo-sensitive cell 1 arranged parallel is in institute State the top of air cavity 10, described absorption-type optical filter 2, collect that mirror 3 is the most parallel, it is described photosensitive to be co-axially located at Element 1 and the centre position of described air cavity 10.
Embodiment two, as in figure 2 it is shown, the order up and down of described absorption-type optical filter 2, collection mirror 3 is exchanged, i.e. absorption-type filter Mating plate 2 changes to collect the lower section of mirror 3.
Described laser diode 6 could alternatively be the monochromatic LED light source through screening;
The effect of described absorption-type optical filter 2 be by laser diode or the high light of monochromatic LED light source filter, Yi Mianying Ring the collection to the fluorescence that high molecular film substrate 5 sends and monitoring.
In embodiment one, two, the material of described absorption-type optical filter 2 is optical coloured glass;Described high molecular film Substrate 5 uses translucent sheet material, specially clouded glass;Described plated film macromolecular material on substrate 5 is MEH-PPV;Described Photo-sensitive cell 1 is heliosensitivity photo-sensitive cell, and concrete model selects the S2386-44k of Bin Song company.
Material due to absorption-type optical filter 2 innately can absorb the wavelength of certain wave band, filters by material behavior Fluorescence, absorption-type optical filter and the order collecting mirror can overturn, to order no requirement (NR) so that fluorescence detection optical path arrangement More flexible;And use absorption-type optical filter, collect light path and have only to collect mirror and optical filter, described collection mirror 3 and absorption The combination of type optical filter 2 instead of traditional collimating mirror 14, film-coating type optical filter 15 and combination of convergent mirror 16, simplifies fluorescence Collect light path, and all optical elements are all co-axially mounted, and reduce resetting difficulty;Described laser diode 6 instead of traditional The combination (conventional laser excitation light path is as shown in Figure 4, Figure 5) of LED17, collimating mirror 14, film-coating type optical filter 15 and convergent mirror 16, Simplify laser excitation light path, make photo-sensitive cell compact structure, easy to carry and use;Meanwhile, absorption-type optical filter compares plated film Optical filter low price, reduces cost.And the film-coating type optical filter that tradition uses leans on is to produce between different thicknesses of layers Interference, by the light transmissive of specific wavelength, this requires that incident illumination must be in the range of certain angle, it requires Film-coating type optical filter must necessarily be placed on the fluorescence direction of propagation after collimating mirror, causes the fluorescence not as using absorption-type optical filter Detection optical path arrangement is flexible;And the collection light path of film-coating type optical filter needs collimating mirror 14, film-coating type optical filter 15, convergent mirror 16 sequentially arrange, so phosphor collection light path is the most more complicated tediously long, cost increases (as shown in Figure 3) the most accordingly.
Due to the high molecular film substrate 5 of transparent or semitransparent sheet material, its material price is than common silicon chip substrate price Lower, coating process is simpler, need not carry out plated film pre-treatment as silicon chip substrate, so reducing cost, as organic Glass, plastics are than the cost savings about 60% of silicon chip, and glass, clouded glass then can save more than 80%.
The foregoing is only preferred embodiments of the present utility model, not in order to limit this utility model, in this practicality Any modification, equivalent substitution and improvement etc. made within novel spirit and principle, should be included in system of the present utility model Within structure.
