Problems solved by technology

[0003] 1. Due to the use of scanning components, the angular resolution of lidar is limited by the accuracy of the scanning mechanism, which weakens the advantages of high spatial and angular resolution of optical imaging
[0004] 2. Since the 3D image of the target is composed of the echo signals of different parts of the target at different times, many laser pulses are required to be arranged in strict accordance with the time sequence to form a complete 3D image, resulting in slow imaging speed and the movement of the platform/target and atmospheric effects can cause 3D image shaking and tearing, which complicates image processing and is not conducive to observing moving ta

Embodiment Construction

[0021] see figure 1 , the structure of the embodiment of the present invention is composed of an optical fiber image bundle 2 composed of 4×4 optical fibers 5 and 16 photodetectors 4, one end of the optical fiber image bundle 2 is bundled together to form a 4×4 array, and polished As the imaging surface 1, a film may also be coated as required. The other end of the optical fiber image transmission bundle 2, that is, the other end 3 of the 16 optical fibers is a free end, which can be stretched freely, and is coupled with 16 photodetectors 4, and the light received by the imaging surface 1 of the optical fiber image transmission bundle 2 The signal is transmitted to the photosensitive surface of the photodetector 4, which constitutes a staring three-dimensional imaging photodetector with 4×4 elements.

[0022] In use of this device, the 4×4 end face of the optical fiber image transmission bundle 2, that is, the imaging plane 1 is placed on the focal plane of the laser three-di...

Abstract

The invention relates to a gaze-type high-resolution 3D imaging detector. The technical proposal of the invention is that the invention comprises an optical coherent fiber bundle formed by optical fibers and a photo sensor. One end of the optical fiber in the optical coherent fiber bundle is bound together with the end surface forming the imaging surface while the other end coupling with the photo sensor. To solve the technical problems in the background technique, the invention provides the gaze-type high-resolution 3D imaging detector, combining optical coherent fiber bundle and a plurality of units of photodetectors with high angular resolution and rapid response.

Description

technical field [0001] The invention relates to photoelectric detection device technology, in particular to a staring type high-resolution three-dimensional imaging detector. Background technique [0002] Laser three-dimensional imaging technology is an active optical detection technology that irradiates the target with a laser beam and detects the laser echo signal of the target to obtain the three-dimensional image information of the target. Since the wavelength of laser is several orders of magnitude shorter than that of microwave, compared with microwave radar, laser three-dimensional imaging technology has the following advantages: extremely high angular resolution, distance resolution and velocity resolution; strong anti-electromagnetic interference ability; concealment Good sex and so on. Compared with passive optical detection technology, laser three-dimensional imaging technology has the following advantages: it is an active detection technology that can work aroun...
