Among the figure: 1, display; 2, fill camera lens; 2 ', light transmitting fiber fills camera lens; 3, the balsaming lens in the lens group; 4, the positive lens in the lens group; 5, eyes; 6, object distance space; 7, light path.
Embodiment
The principle of the utility model is as shown in Figure 1: AB is between one times of focal length FF of positive lens CC ' when the object that is exaggerated (here being display); The light AE that the A point of AB sends is parallel to primary optical axis XX ' also through forming EU through positive focal point F after the refraction of positive lens CC ' E point; And the bar light in addition that the A of AB point sends passes through the O point formation OS of positive lens, and the extended line of OS and EU intersects at A ' point.In like manner, the light that the B of AB is ordered other end at A ' after positive lens CC ' refraction forms B ', and promptly A ' B ' is the amplification virtual image of AB.
At this moment; When we recharge a positive lens GG ' (focal distance f f) between object AB and positive lens CC '; The light AL that the A point of AB sends is parallel to primary optical axis XX ' through positive lens GG ', and AL reflects into LK at the L place, and LK reflects once more at the K place through original positive lens CC ' and forms KD; Another light that the A point sends positive lens GG ' refraction through filling earlier; Through original positive lens CC ' refraction, form MP again, the extended line of KD and MP meets at A 〞 point; In like manner, the B of AB point light forms other end virtual image B 〞 after positive lens GG ' and twice refraction of positive lens CC '.Promptly be another amplification virtual image A 〞 B 〞 of AB.Compare virtual image A ' B ' and virtual image A 〞 B 〞, obviously visual angle β is much larger than θ, and promptly the virtual image A 〞 B 〞 of object AB will be much larger than the virtual image A ' B ' of object.That is when after having recharged a suitable positive lens between the original and positive lens, magnification will be multiplied until the requirements that reaches us.
During enforcement, a kind of fill superposing type optics magnification engine device according to above-mentioned former reason display 1, fill the balsaming lens 3 in camera lens 2, the lens group, the positive lens 4 in the lens group is formed; Display 1, balsaming lens 3, the positive lens 4 in the lens group of filling in camera lens 2, the lens group are in the closely stack (seeing Fig. 2,4,5) in one line of primary optical axis coaxial position.The display surface of display 1 is placed towards camera lens; The one side of filling camera lens (2) is close to the display surface of video display (1); Fill the another side of camera lens (2) and the negative lens face close proximity of the balsaming lens in the lens group (3), the bigger one side close proximity of convexo-convex curvature of the positive lens face of balsaming lens (3) and the positive lens (4) in the lens group.
When reality is used the display show image; Image light is that light path 7 (seeing Fig. 4,5) is sent by display 1; At first through the convex lens of filling camera lens 2 (see Fig. 5, fill the convex lens of camera lens 2 two-sided towards placing arbitrarily, promptly wherein one side both can also can be towards balsaming lens 3 towards display 1) refraction; Again through balsaming lens 3 and positive lens 4 eyeground of refraction input continuously, the positive image in the very big video display of the retina formation enlargement factor of eyes 5.
When desire is amplified to the screen size of big display 1 with the screen of the display 1 of smaller szie; Can between this is than small displays 1 and filling camera lens 2, fill scalable tapered light guides fiber filled camera lens 2 ' (as shown in Figure 4) once more; According to the photoconduction principle; Light transmitting fiber fill camera lens 2 ' the image of inlet end will be exaggerated and be directed to light transmitting fiber fill camera lens 2 ' exit position (designing this discharge area equates with needed display area); Light transmitting fiber was filled camera lens 2 ' exit and was equivalent to the display surface of the video display 1 of required area this moment, thereby obtained the amplification effect with required display 1 same size.For example; When the display 1 of buying less than 0.5 inch; And when having only 0.2 inch display 1, can and fill that the filling access area be 0.2 inch between the camera lens 2 at this display of 0.2 inch 1, discharge area be 0.5 inch light transmitting fiber fill camera lens 2 '; At this moment the light path 7 sent of 0.2 inch display 1 is filled camera lens 2 ' fill camera lens 2 ' exit at light transmitting fiber just to have formed 0.5 inch image through this light transmitting fiber, and this image plane has just substituted 0.5 inch display 1.
When filling superposing type optics magnification engine when placing the optics module; Only need display 1, fill balsaming lens 3 in camera lens 2, the lens group, positive lens 4 in the lens group and be in the primary optical axis coaxial position closely stack is in one line, display 1, balsaming lens 3, the 4 relative primary optical axis of the positive lens in the lens group of filling in camera lens 2 (add when needing light transmitting fiber fill camera lens 2 '), the lens group are vertically placed (seeing Fig. 2,4,5).Need not to consider the distance between each object.Because optical lens belongs to precision-fabricated, so, need not to regulate again as long as optical lens is qualified can accurately be placed.
This filling superposing type optics magnification engine; Make that the video optics module that is made up of display and compound lens is more compact; Assemble convenient, accurate, put in place easily; Amplification effect is also better, promptly utilize the vacant object distance space (comparison diagram 2 and Fig. 3) of script gone up between original display and the enlarging lens (being eyepiece in video eyeglasses video optics module), has added suitable ordinary optical enlarging lens of parameter or light transmitting fiber enlarging lens in addition and has been clipped between the display and eyepiece that (being close to) be exaggerated; Refractive index is increased; Amplify reduced distances, amplify the virtual image and increase (parameter that can design this piece interpolation camera lens as required is to reach enough big magnification), reach the purpose that video optical mode set product image aspects is bigger, volume is littler, more economical, profile is more attractive in appearance.Again because of adopting superposing type that (all camera lenses also are close to installation) is installed; So assembling and do not need accurately to measure position and the adjustment repeatedly between display and the camera lens when making mould; Can settle (because of optical lens has reached accuracy standard) at one go, not only improve efficiency of assembling but also improved assembling degree of accuracy and product quality.
Because of the photoconduction amplifier is that the image of display is delivered to outlet and amplifies from its inlet; So the exit face of photoconduction amplifier can be used as indicator screen and treats, like this, promptly can with the photoconduction amplifier place fill camera lens before; Make the application of light transmitting fiber amplifier in video eyeglasses become possibility; Make more small miniscope also can obtain the big the same amplification effect of display, increased the selection channel, broken the monopolization of the miniature LCD material of certain model.This is the expansion of photoconduction amplifier to the filling camera lens, in fact also can be classified as the filling camera lens.
