At the radiation of the ultraviolet light source, the camera can instantly shoot the trace of the potential-sweat fingerprint, and can directly observe the trace after the shooting, so that the police security organs can rapidly lockout the suspect, thereby accelerating the detection rate of crime; moreover, the camera has small volume, and is convenient to carry, and is convenient to be operated.
Description
Technical field
The utility model belongs to a kind of criminal investigation equipment, especially a kind of digital ultraviolet camera of finding and taking the sweat latent fingerprint vestige of criminal case crime scene that is mainly used in.
Background technology
Effectively find and take the sweat latent fingerprint that the suspect in flagrant delict stays, can grasp suspect's feature rapidly, help the detection of case.Usually under the natural light condition, the difficulty of extracting the sweat latent fingerprint is bigger, and the easier interference that is subjected to background.After the illumination by auxiliary ultraviolet light source, take the extraction ratio that can improve the sweat latent fingerprint greatly with ultraviolet camera.
Original ultraviolet camera is film type, has following problem usually: the film after 1, taking pictures just can be printed to photo after need developing and printing into egative film.2, can not the direct viewing effect after this ultraviolet camera is taken, delay the efficient of solving a case.3, operation is comparatively complicated.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and gets final product direct viewing at shooting sweat latent fingerprint vestige that can be instant under the irradiation of ultraviolet source, after taking, helps the quick lock in suspect of public security organ, accelerate to solve a case efficient and volume are little, be easy to carry, easy to operate digital ultraviolet camera.
The technical scheme that provides according to the utility model, on the imaging fuselage, bayonet socket is set, the front end of imaging fuselage is connected with the shank housing of tubular by bayonet socket, in the imaging fuselage, be provided with electrode tip holder, electrode tip holder is provided with electrode, be provided with ultraviolet filter at shank housing front end, be provided with and the ultraviolet object lens that cooperates ultraviolet filter in the shank housing at ultraviolet filter rear portion, in the shank housing at ultraviolet object lens rear portion, be provided with ultraviolet imaging enhancer, be provided with the relay system that cooperates with ultraviolet imaging enhancer in inside, shank housing rear end, the image-forming component in described relay system and the imaging fuselage cooperates.
On the shank housing of ultraviolet filter front end, be provided with the lens cap that buckle closure is lived ultraviolet filter.Be connected with tripod in shank housing lower sidewalls.
The utility model can be instant under the irradiation of ultraviolet source shooting sweat latent fingerprint vestige, get final product direct viewing after the shooting, help the quick lock in suspect of public security organ, accelerate to solve a case efficient and volume are little, are easy to carry, and be easy to operate.
Description of drawings
Fig. 1 one-piece construction synoptic diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: bayonet socket 7 is set on imaging fuselage 10, the front end of imaging fuselage 10 is connected with the shank housing 4 of tubular by bayonet socket 7, in imaging fuselage 10, be provided with electrode tip holder 9, electrode tip holder 9 is provided with electrode 8, be provided with ultraviolet filter 2 at shank housing 4 front ends, be provided with in the shank housing 4 at ultraviolet filter 2 rear portions and the ultraviolet object lens 3 that cooperates ultraviolet filter 2, in the shank housing 4 at ultraviolet object lens 3 rear portions, be provided with ultraviolet imaging enhancer 5, be provided with the relay system 6 that cooperates with ultraviolet imaging enhancer 5 in inside, shank housing 4 rear end, the image-forming component in described relay system 6 and the imaging fuselage 10 cooperates.
On the shank housing 4 of ultraviolet filter 2 front ends, be provided with buckle closure and live the lens cap 1 of ultraviolet filter 2.Be connected with tripod 11 in shank housing 4 lower sidewalls.
The course of work of the present utility model is as follows:
After institute's photo-object (as fingerprint) is thrown light on by uviol lamp, after its faint ultraviolet light enters ultraviolet object lens 3 (other spectrum are filtered by optical filter), with the cathode plane of target imaging at ultraviolet imaging enhancer 5, the faint optical imagery of this kind becomes electronic image by the opto-electronic conversion of ultraviolet imaging enhancer 5 photocathodes, electronic image obtains tens thousand of times enhancing by the effect of electron-optical system highfield then, at last convert electronic image to optical imagery that brightness has strengthened again by the video screen of ultraviolet imaging enhancer 5, be imaged on after this image amplifies by relay system 6 then on the CCD of imaging fuselage 10 and take pictures, can obtain desirable image, so that observe and gather.
Wherein, lens cap 1 be used for protecting ultraviolet filter 2 deposit and carry that process is collided with, scuffing etc.; Ultraviolet filter 2 mainly contains two effects: 1) cross filtering ultraviolet light other spectrum light in addition; 2) the protection ultraviolet imaging enhancer is not subjected to strong illumination and quick aging; Ultraviolet object lens 3 is used for institute's photo-object is carried out imaging; Relay system 5 amplifies the back with the picture on the ultraviolet imaging enhancer video screen and becomes on the CCD of camera.
