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.
