Abstract
The utility model relates to a colorful image optical fiber transmitter which is composed of a lens (1), an optical fiber (4), an image display (5), etc. The utility model is characterized in that the lens (1) and the image display (5) are connected by an optical fiber bundle (4), and optical channels are formed between the optical fiber bundle and the lens and between the optical fiber bundle and the image display. Since the utility model utilizes the optical fiber and light conduction technique to transmit images, the utility model can completely avoid outside electromagnetic interference and influence of environment temperature, humidity, etc., and the operation is stable and reliable. In addition, the utility model has the advantages of simple structure, convenient installation and use, no need of a power supply, low cost, wide application and no need of maintenance.
Description
Existing electronic technology graphic transmission equipment all is to adopt photoelectric conversion technique to realize the image transmission as videophone, watch-dog, CATV (cable television) etc.Though their demands are extensive, the shortcoming that have complex structure, cost an arm and a leg, is subject to disturb.
The utility model belongs to the fibre-optic light guide technical field.It aims to provide a kind of simple in structure, and is cheap, interference-free coloured image transmission equipment.Make periscope, rearview mirror and videophone owing to possess novel can being widely used in of above this reality of advantage.The utility model is achieved in that to be consulted shown in the accompanying drawing one:
The utility model is made up of camera lens (1), fibre-optic bundle (4) imagescope parts such as (5), it is characterized in that constituting optical channel to each other by fibre-optic bundle (4) connection between camera lens (1), the imagescope (5); Object lens (2), photo-coupler (3), carriage (8), shell parts such as (12) are formed camera lens (1), and imagescope (5) is made up of light decoupler (6), picture screen (7) carriage (9), cabinet parts such as (13).Object lens (2) photoconduction coupling mechanisms (3), photoconduction decoupler (6) are to make with convex lens, and fibre-optic bundle (4) is the parallel bunchy arranged side by side of many light transmitting fibers that equates with the diameter equal length.Picture screen (7) is made with frosted glass or telescope ocular.
Principle of work of the present utility model such as following, consult shown in the accompanying drawing one:
According to geometric optical theory as can be known, after entering object lens (2), the parallel rays that comes from object lens (2) incident at a distance will focus on its focus O by the refraction action of convex lens
1Photoconduction coupling mechanism (3) is to be made of a slice diameter less convex lens and carriage (8), it is that the light of photoconduction coupling mechanism (3) outgoing becomes the less parallel light velocity of a diameter that the focus that the position of bracket (8) makes little convex lens and the focus of object lens (2) overlap then from little convex lens, and this light velocity diameter equates with fibre-optic bundle (4).Like this photoconduction coupling mechanism (3) realized parallel rays with object lens (2) incident convert to the less parallel beam of diameter with and the cross-sections match of light transmitting fiber (4) reach the maximal efficiency of luminous energy transmission.Parallel beam incident optical bundle (4) afterwards, according to fibre-optic performance, incident beam the optical fiber inside surface through repeatedly the reflection after from other end outgoing.This light beam is injected the convex lens post-concentration of decoupler (6) forward in focus O
2And directive picture screen (7) or telescope ocular.Because picture screen (7) is that frosted glass is made, so produce colored image on the glass planar.If change telescope ocular on the position of frosted glass, the distant place scenery that is exaggerated can be seen in the position of bracket (9) in eyepiece.Locator card (10) on camera lens (1) shell is to be used for installing and fixing camera lens (1).Locator card (11) on the cabinet (13) of imagescope (5) is to be used for fixing the usefulness that imagescope (5) is installed.
In sum, therefore the utility model can avoid influence, the working stability of factors such as external electromagnetic, interference and ambient humidity temperature reliable owing to utilize the light guide techniques images fully.In addition the utility model simple in structure easy to install need not power supply, so it is with low cost, and is extensively practical, need not maintenance.The utility model is the desirable coloured image transmitting device of a new generation.
Claims (4)
1, the utility model relates to a kind of coloured image Optical Fiber Transmission device, it is to be made of camera lens (1), fibre-optic bundle (4), imagescope parts such as (5), it is characterized in that constituting optical channel to each other with fibre-optic bundle (4) connection between camera lens (1), the imagescope (5); Object lens (2), photo-coupler (3), carriage (8), shell parts such as (12) constitute camera lens (1), and imagescope (5) is made of light decoupler (6), picture screen or eyepiece (7), carriage (9), cabinet parts such as (13).
