Embodiment Construction

[0015] Below in conjunction with accompanying drawing, the present invention will be further described.

[0016] see figure 1 , the single optical path stereo magnifying glass system includes an optical information collection device, a digital signal processing device and an optical information restoration device sequentially arranged along the optical path. The optical information collection device includes two groups of reflective mirrors (1 and 3; 2 and 4) opposite to each other, an optical lens group and an image sensor chip. The two sets of reflectors are placed symmetrically to each other. The optical axis of the optical lens group coincides with the symmetry axis of the reflector. The image sensor chip is perpendicular to the optical axis with the center on the optical axis. The optical lens 5 has a fixed focal length and can magnify the image by a certain factor, such as 2.5X, 3X, 3.5X, 4X, etc. The light reflected from the surface of the object enters the signal a...

Abstract

The invention discloses a stereoscopic vision magnifier system of a single light path, which comprises an optical information collecting device, a digital signal processing device and an optical information restoring device sequentially arranged along a light path, solves the problems of a traditional stereoscopic vision magnifier, has convenient use and obvious stereoscopic vision effect by freeing a user from respectively adjusting the positions and the focal lengths of a left optical system and a right optical system, and has a great coverage range of the depth of field so that the user head can move in a larger space without influencing the image quality. An amplification factor can be changed according to practical needs by electronically zooming, and the whole practical use process can be recorded and shot in real time for a user to play back and view.

Description

technical field [0001] The invention relates to a magnifying glass, in particular to a single optical path stereo magnifying glass system. Background technique [0002] The stereo magnifiers currently on the market all use pure optical principles to place two optical systems in front of the left and right eyes respectively to achieve the effect of magnifying objects. In order to avoid eye physiological effects during use, the positions and focal lengths of the two optical systems need to be adjusted separately so that the optical axes of the magnifying glass coincide with the optical axes of the left and right eyes respectively. As the magnification of the magnifying glass increases, the depth of field decreases accordingly, and the user's head is required to remain in a relatively fixed position. The stereo magnifier with variable focal length has a complex optical structure, and a large number of lenses increases the overall weight of the magnifier. These deficiencies al...
