Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The concealed image transmission of wireless ultraviolet light of the present utility model comprises transmitting terminal and corresponding receiving terminal two parts.
As shown in Figure 1, transmitting terminal is used for collection, the compression of image information to be processed and emission, comprise video image acquisition module 1, video image acquisition module 1 is connected with arm processor 1, communication interface 1, light source driver module 4 and ultra violet light emitter 5 signal successively.
Video image acquisition module 1 is selected digital camera, be connected on development board, the data image signal that gathers is passed to arm processor 1, arm processor 1 is realized the compressed encoding processing procedure of image, select Samsung S3C2440A development board, both can gather image, can realize also that the compressed encoding of image was processed; Communication interface 1 is the FPGA device;
Ultra violet light emitter 5 is selected ultraviolet leds, and ultraviolet LED has following advantage: 1) LED machine life length and environmental protection low in energy consumption.2) shock resistance is strong.3) machine volume I flexible configuration.4) LED low-voltage direct work, power is adjustable.The ultraviolet leds that adopts, its wavelength are 365nm, exemplary operation voltage 4V, luminous power 40mW.
As shown in Figure 2, receiving terminal comprises Photoelectric Detection module 6, and Photoelectric Detection module 6 is connected with photoelectric conversion module 7, signal amplification filtering module 8, communication interface 29, arm processor 2 10 and video image display module 11 signal successively.Arm processor 2 10 is selected Samsung S3C2440A development board, and communication interface 29 is selected the FPGA device.The picture signal that receives is recovered original picture signal by arm processor 2 10.
The photomultiplier of signal amplification filtering module 8, photoelectric conversion module 7 and Photoelectric Detection module 6 being integrally formed of three, the window that this photomultiplier receives ultraviolet light is equipped with filter.Photomultiplier (PTM) is a kind of light-detecting device with high sensitivity and ultrafast time response, its advantage: the one, and the multiplication factor of photomultiplier is very high, and still keeps signal to noise ratio preferably; The 2nd, photomultiplier can detect very faint light signal, and is even faint to detecting the light signal that only has a photon; The 3rd, can be very large with respect to other the photosurface area of detector photomultiplier.
The course of work of the utility model device is:
