Background technology
During the material evidence camera material evidence being collected evidence further to carry out the visual plant that vestige is identified, is the equipment that needs that foundation is provided for solving a case, deciding on a verdict.
General camera is the fingerprint material evidence image that is difficult to extract smooth non-infiltration such as coating wall, photo, mirror, plastics, paint face, glass, adhesive tape, smooth paper, stainless steel material or pottery and smooth semi-permeable object surface, therefore, must be equipped with ultraviolet or infrared light supply when as the material evidence camera vestige being collected evidence, potential vestige effectively excites vestige fluorescence under the irradiation of ultraviolet or infrared light supply, make the material evidence camera can take out the visual image of human eye, in order to potential vestige is identified.
General ultraviolet or infrared camera adopt conventional camera technology, must make film, and develop and print photo etc., can not carry out real-time observation and directly digital output, can not satisfy the requirement of some criminal investigation work.
The utility model content
The purpose of this utility model is exactly to provide a kind of criminal investigation simple in structure, applied widely, easy to use with full spectrum digital camera in order to overcome the defective that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of criminal investigation is with full spectrum digital camera, comprise digital camera fuselage, be installed on the camera lens of front fuselage and be located at the full spectrum reflective mirror of camera lens back, be provided with imageing sensor in the described fuselage, this imageing sensor is accepted the light through full spectrum reflective mirror, and light is converted into the image that can be shown in display screen on the fuselage or be stored in RAM (random access memory) card in the fuselage, be provided with replaceable filter before the described camera lens.
Between described camera lens and the fuselage for removably connecting.
When criminal investigation was used for the ultraviolet light shooting with full spectrum digital camera, described camera lens was quartz lens, is provided with the ultraviolet-transmitting filter before the quartz lens, is provided with the uviol lamp tube before this ultraviolet-transmitting filter; When criminal investigation was used for the infrared light shooting with full spectrum digital camera, described camera lens was zoom lens, is provided with the infrared ray filter before the described zoom lens.
Described ultraviolet-transmitting filter or saturating infrared ray filter are fixed on the Jing Quan, between this Jing Quan and the camera lens for being threaded or buckle is connected.
Described uviol lamp tube comprises the cylindrical lampshade of outside and is located at ultraviolet light source in the cylindrical lampshade, and the outside of described cylindrical lampshade is provided with handle, and the lead of described ultraviolet light source passes handle and is connected with external power source.
The diameter of described cylindrical lampshade is 10～15cm, and height is 10～20cm.
This camera adopts 1,800 ten thousand pixel, is provided with the draw-in groove that device stores card in the camera, and this camera can be connected with computer, directly observes the effect of photographic images by computer.
When using camera of the present utility model to be used for the ultraviolet light shooting, with the fixing camera of tripod or rephotograph stand, with the close object surface of uviol lamp tube, adjust focal length, make clear being presented on the display screen in object surface, mobile camera or object are determined the fingerprint position, post scale, slave on one's body display screen or by the computer observed image.When using camera of the present utility model to be used for infrared light to take, camera lens is changed to zoom lens, and the infrared ray filter is set before zoom lens gets final product.When using camera of the present utility model to be used for the visible light shooting, only need to use common lens, before the camera lens colour filter mustn't be set.
Compared with prior art, the utlity model has following advantage:
(1) fuselage interior of camera of the present utility model is not used traditional shielding of ultraviolet or ultrared photo-sensitive cell, but removable optical filtering is set before camera lens, camera can be taken the material evidence mark image under ultraviolet light, visible light and the infrared ray respectively normally, and make ultraviolet ray or infrared ray free of losses, no colour cast intactly by optical filtering, be conducive to improve camera evidence obtaining vestige imaging definition;
(2) the inner imageing sensor that adopts of camera of the present utility model, the image that can directly take by the display screen observation of camera can also carry out observed image the digitlization storage;
(3) easy, the intuitive display of camera operation of the present utility model is applied widely.
