Title:
TELESCOPE, AND ELECTRONIC EYEPIECE AND EYEPIECE ADAPTER FOR TELESCOPE
Document Type and Number:
WIPO Patent Application WO/2022/170950
Kind Code:
A1
Abstract:
A telescope (100), comprising a microdisplay (11), a beam combiner (12), a dichroitic beam splitter (13), and an image sensor (14). The beam combiner (12) receives light from an objective lens (2) and light from the microdisplay (11), and mixes same. The dichroitic beam splitter (13) allows most of visible light in the light mixed by the beam combiner (12) to enter a first optical path to an eyepiece (3), and at least part of invisible light and a small number of visible light having a predetermined wavelength to enter a second optical path to the image sensor (14). The image sensor (14) obtains a detection image representing an optical image formed by the objective lens (2) and an electronic image displayed on the microdisplay (11). Also disclosed are an electronic eyepiece (10) and an eyepiece adapter (10', 10A') for the telescope (100). The detection image representing the optical image formed by the telescope objective lens (2) and the electronic image displayed on the microdisplay (11) can be obtained. Thus, registration information of the optical image and the electronic image can be obtained, thereby solving the problem of registration between the electronic image and the optical image.
