The course of work of head carried type self lighting video photographic system of the present invention:
When throwing light on shooting, the illumination camera is fixed on to be worn on the support.Illumination light is sent by white light source, arrive the illumination camera through Optical Fiber Transmission, illuminating bundle is through the effect of converging of convergent lens, by entering after the control of diaphragm to light beam on the protruding plane of protruding flat illuminating lens, illumination light by cylinder reflector, illuminates the zone of required illumination being penetrated by the plane of protruding flat illuminating lens after the converging action of the flat illuminating lens of excess convexity, regulate the relative position of convergent lens, diaphragm and protruding flat illuminating lens, making illuminator is the Kohler illumination mode.In illumination, to make a video recording, the shooting direction of beam propagation is opposite with the illumination light direction of propagation, and the elliptic reflecting surface reflection back of process cylinder reflector is along optical axis O
1O
2Propagate, reflected light converges to imaging on the sensitization plane of charge-coupled image sensor through imaging lens again, the relative position of regulating cylinder reflector and imaging lens can be adjusted to the enlargement ratio and the shooting depth of focus of picture, charge-coupled image sensor sensitization plane changes into electric signal with light signal, the electric signal of the image of taking the photograph is transferred to the charge-coupled device controller through electrical signal transmission line, the electric signal of the image of taking the photograph just can be shown synchronously by the terminal display that is connected with the charge-coupled device controller, perhaps imports computing machine and carries out subsequent processes.
Compare advantage of the present invention with technology formerly:
1) the present invention has realized wear-type synchronous lighting and shooting, and convergent lens, diaphragm and protruding flat illuminating lens have constituted illuminator, and the lighting system of taking is the Kohler illumination mode, and make cylinder reflector between the surround in shadow-free;
2) cylinder reflector, imaging lens system and charge-coupled image sensor sensitization plane constitute camera system, charge-coupled image sensor sensitization plane is converted into electric signal with light signal, control by the charge-coupled device controller, can carry out good real-time photography to institute field of illumination and doctor's surgical procedure, convenience is further handled or is shown in real time by the terminal display that links to each other with the charge-coupled device controller;
3) axis of symmetry of cylinder reflector overlaps with lighting optical axis oo ', the light beam that makes illuminating bundle and shooting gather light is coaxial, guarantee that shooting and illumination are the same area, the cylindrical side of cylinder reflector and rounded bottom surface all are used to prevent the quality of the imaging that illumination light increases again the interference of shooting by blacking simultaneously;
4) link to each other with head-wearing device among the present invention have to be connected with white light source is used for photoconduction optical fiber that goes out and the electrical signal transmission line that is connected with charge-coupled image sensor sensitization plane, and optical fiber and electrical signal transmission line are all longer, and flexibility is better, is convenient to remote-controlled operation;
5) the part-structure compactness of wearing of the present invention, light, a whole set of optical system is simple, lighting device and camera head relative fixed, gently little, be convenient to wear.
