Direct-view low-light-level stereoscopic imaging night-vision device

Abstract

The invention discloses a direct-view low-light-level stereoscopic imaging night-vision device, which mainly solves the problems that the conventional direct-view low-light-level imaging device cannot supply a stereoscopic low-light-level image with a sense of depth and a sense of layer. The direct-view low-light-level stereoscopic imaging night-vision device comprises an object lens optical system (31), a photocathode (37), a microchannel plate (38), a fluorescent panel (39) with a 180-degree image-twisting property, and an ocular lens system (34), wherein a recording zoom lens array (30) isarranged at the front end of the object lens optical system (31) and a reconstructing zoom lens array (33) is put at the back end of the fluorescent panel (39), so that a multi-visual angle imaging system structure by the double zoom lens arrays is formed; the fluorescent panel (39) is arranged at a focal plane of the reconstructing zoom lens array (33); and within a spatial range of each corresponding lens unit of the reconstructing zoom lens array (33), the reversible calibration on the low-light-level stereoscopic imaging depth is implemented. The direct-view low-light-level stereoscopic imaging night-vision device has the advantages of wide depth of field, switching between a stereoscopic imaging mode and a two-dimensional imaging mode and reversible calibration on observing depth of field, and can be applied to the fields of night vision, medical imaging, underwater imaging, dark room measurement and the like.

Description

technical field [0001] The invention belongs to the field of imaging technology, and in particular relates to a direct-view low-light three-dimensional imaging night vision device, which can be used in night vision, medical imaging, underwater imaging, darkroom measurement and other fields. Background technique [0002] The direct-view low-light imaging system is a photoelectric imaging system using light enhancement technology. It can greatly improve the visual performance of the human eye in low light. Since the system can operate under extremely low illuminance (10 -6 lx~10 -1 lx) works completely "passively", so it has been rapidly developed and widely used in night vision, medical imaging, underwater imaging, photon imaging and other fields. The traditional direct-view low-light imaging system is mainly composed of three parts: the objective optical system, the low-light image intensifier, and the eyepiece system, such as figure 1 As shown, its working principle is:...
