WIPO Patent Application WO/2022/170951
Kind Code:
A1
Abstract:
An electronic eyepiece (10), an eyepiece adapter, and a telescope. The electronic eyepiece comprises a light combining lens (11), a relay lens (12), an optical eyepiece (13) and a microdisplay (14), which is disposed on one side of the light combining lens (11), wherein the relay lens (12) images an image formed by an objective of a telescope onto a target image plane (IM2); and the light combining lens (11) and the microdisplay (14) are arranged such that light from the objective of the telescope and light from the microdisplay (14) are mixed by means of the light combining lens (11) and enter the relay lens (12), and an image displayed by the microdisplay (14) is imaged onto the target image plane (IM2) by means of the relay lens (12). By arranging a relay lens (12) downstream of a light combining lens (11), the position of a real image plane to be observed by means of an optical eyepiece (13) is adjusted, such that the optical eyepiece (13) can use various existing eyepieces with different specifications and standardized interfaces, the adaptability of an apparatus is improved, and the cost is reduced.
