Abstract
The invention relates to a full spectrum digital camera for criminal investigation. The full spectrum digital camera comprises the frame of a digital camera, a lens installed at the front end of the body, and a full spectrum reflective mirror arranged behind the lens. The frame is internally provided with an image sensor; the image sensor receives light passing through the full spectrum reflective mirror and converts the light into images which can be displayed on a display screen on the frame or stored in a memory in the frame; a filter mirror is arranged in front of the lens of the camera; when the camera is used for ultraviolet light shooting, the lens is a quartz lens, an ultraviolet ray transmitting filter mirror is arranged in front of the quartz lens; an ultraviolet lamp cylinder is arranged in front of the ultraviolet ray transmitting filter mirror; and when the camera is used for infrared light shooting, the lens is a zooming lens, and an infrared ray transmitting filter mirror is arranged in front of the zooming lens. Compared to the prior art, an image sensor is employed inside the camera, a shot image can be observed directly through the display screen of the camera, the observed image can also be digitally stored, the operation is simple, the display is visual, and the application scope is wide.
Description
Technical field
The present invention relates to a kind of camera, especially relate to full spectrum digital camera for a kind of criminal investigation.
Background technology
When material evidence camera, material evidence being collected evidence further to carry out the visual plant of vestige evaluation, is the equipment that needs that foundation is provided for solving a case, deciding on a verdict.
Generally camera is the fingerprint material evidence image on the smooth non-infiltrations such as very difficult extraction coating wall, photo, mirror, plastics, paint face, glass, adhesive tape, smooth paper, stainless steel material or pottery and smooth semi-permeable object surface, therefore, when vestige evidence obtaining as material evidence camera, must be equipped with ultraviolet or infrared light supply, potential vestige effectively excites vestige fluorescence under the irradiation of ultraviolet or infrared light supply, make material evidence camera can take out the visual image of human eye, to latent trace 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 direct digital output, can not meet the requirement of some criminal investigation work.
Summary of the invention
Object of the present invention is exactly to provide full spectrum digital camera for a kind of criminal investigation simple in structure, applied widely, easy to use in order to overcome the defect that above-mentioned prior art exists.
Object of the present invention can be achieved through the following technical solutions:
A kind of full spectrum digital camera for criminal investigation, comprise digital camera fuselage, be installed on the camera lens of front fuselage and be located at camera lens full spectrum reflective mirror below, in described fuselage, be provided with imageing sensor, 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 fuselage or be stored in RAM (random access memory) card in fuselage, before described camera lens, be provided with replaceable filter.
Between described camera lens and fuselage for removably connecting.
In the time that criminal investigation is taken for ultraviolet light with full spectrum digital camera, described camera lens is quartz lens, is provided with ultraviolet-transmitting filter before quartz lens, before this ultraviolet-transmitting filter, is provided with ultraviolet tube-lamp; In the time that criminal investigation is taken for infrared light with full spectrum digital camera, described camera lens is zoom lens, before described zoom lens, is provided with infrared filter.
It is upper that described ultraviolet-transmitting filter or thoroughly infrared filter are fixed on Jing Quan, between this Jing Quan and camera lens for being threaded or buckle is connected.
Described ultraviolet tube-lamp comprises the cylindrical lampshade of outside and is located at the ultraviolet light source in cylindrical lampshade, and the outside of described cylindrical lampshade is provided with handle, and the wire of described ultraviolet light source is through handle being 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 of device memory card in camera, and this camera can be connected with computer, directly observes the effect of photographic images by computer.
While using camera of the present invention to take for ultraviolet light, by tripod or rephotograph stand fixed camera, by ultraviolet tube-lamp near object surface, adjusting focal length, make clear being presented on display screen in object surface, mobile camera or object, determine fingerprint position, post scale, display screen with it of slave or by computer observed image.While using camera of the present invention to take for infrared light, camera lens is changed to zoom lens, and before zoom lens, infrared filter is set.In the time using camera of the present invention to take for visible ray, only need to use common lens, before camera lens, colour filter mustn't be set.
Compared with prior art, the present invention has the following advantages:
(1) fuselage interior of camera of the present invention 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 ray and infrared ray respectively normally, and make ultraviolet ray or infrared ray free of losses, without 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 invention, the image that can directly take by the display screen observation of camera, can also carry out digitlization storage by the image of observing;
(3) easy, the intuitive display of camera operation of the present invention, applied widely.
