Abstract

A reflective stereo image-watching lens of the utility model belongs to a watching lens of stereo images, in particular to a stereo watching lens that inverted and reflects images. The device has a total reflection prism in the tube, the frontal end of which is a watching hole, and the reflection side faces an invert image to be watched, the incident angle and the reflective angle formed among the image, the total reflection prism and eyepieces are 150 degrees to 170 degrees. The device has the advantages of simple structure, good watching effects, easy watching, no influence on lightness and color, that tridimensional stereo images can be watched, and that dynamic and stationary images of double pictures with different sizes and different distances can be watched.

Description

Reflective stereoscopic image is watched mirror

The utility model belongs to the two pictures of stereoscopic image and watches mirror, particularly to a wherein visual side-inverted processing, reflects the stereos copic viewing device of reduction again.

Make a general survey of the viewing method of existing stereotelevision and stereoscopic photograph, time division type, three-dimensional complementary color method and raster pattern etc. roughly arranged, they all in various degree existence flicker, reduce the problem of brightness and color lightness, and price is expensive.With three-dimensional two picture prints is example, and prior art is two picture stereoscopic photographs to be put into a special device watch, and the size of picture, all is restricted apart from distance, and brightness and color lightness can reduce, and effect is greatly affected, and this installation cost is higher; And for example the raster pattern stereoscopic photograph will be taken with specialized camera, and developing device is expensive, and the sharpness of this type of photo is still waiting to improve.

The purpose of this utility model provides a kind of stereotelevision and image viewing mirror, and it is simple in structure, and image viewing is effective, watches easily, and brightness and color are unaffected, also are not subjected to the influence of image size and viewing distance distance.

Realization technical scheme of the present utility model is: one piece of total reflection prism is housed in lens barrel, and the incident that forms between image, total reflection prism and eyepiece three is 150～170 ° with the reflection angle.When watching image, a glance direct viewing image, another is watched by this mirror, and wherein a width of cloth is oppositely visual, and total reflection prism reflects reduction with reverse picture, and itself and normal image are coincided, just can obtain meeting the 3 D stereo picture of people's normal vision custom.

Below, the specific embodiment of the present utility model according to Figure of description provides is further described its structure.

Fig. 1 is a surface structure synoptic diagram of the present utility model;

Fig. 2 is a principle schematic of the present utility model.

Referring to Fig. 1, the lens barrel 3 rear and front end openings of this device, front end is established object lens 6, and eyepiece 4 is established in the rear end, one piece of total reflection prism 1 is housed in mirror lens barrel 3, and making the incident that forms between image 2, the reflecting surface of total reflection prism 1 and eyepiece 4 threes is 150～170 ° of (see figure 2)s with the reflection angle.Referring to Fig. 2, two picture stereoscopic images 2 of symmetrical expression are placed the beholder dead ahead, the positive image 2 of beholder's a glance 5 direct viewings, another eye 5 is watched oppositely image 2 of another width of cloth by catoptron 1, suitably adjust the position, make image that eyes see separately 2 complete when overlapping, just can produce the well three-dimensional image of brightness and color.When this uses total reflection prism 1, can obtain the refraction effect visual angle bigger than general flat reflector; Owing to adopted reflection to watch method, can make image not have distortion, brightness, color lightness can not be affected yet, and the size and the distance of image are also unrestricted.

From technique scheme of the present utility model, this mirror is simple in structure, can largely reduce operation easier; Watch method owing to adopted realistic images to reduce, so the distance of image size and viewing distance can be unrestricted with side-inverted and reflection; Adopt total reflection prism to be inverted the mode that overlaps, the brightness and the color of image can not be affected.

Claims

1, a kind of reflective stereoscopic image is watched mirror, it is characterized in that being equipped with in lens barrel one piece of total reflection prism, and the incident that forms between image, total reflection prism and eyepiece three is 150～170 ° with the reflection angle.
