A telescope, including a microdisplay, a beam combiner, a dichroitic beam splitter, and an image sensor. The beam combiner receives light from an objective lens and the microdisplay, and mixes same. The dichroitic beam splitter allows at least part of invisible light and a small part of visible light having a predetermined wavelength to enter a second optical path leading to the image sensor. The image sensor obtains a detection image representing an optical image formed by the objective lens and an electronic image displayed on the microdisplay. Also disclosed are an electronic eyepiece and an eyepiece adapter for the telescope. The detection image representing the optical image and the electronic image can be obtained.

A reticle adjusting structure includes a reticle plate, a beam combination lens, and a magnification variation lens set arranged in sequence along a visible-light optical axis, and a display module arranged outside of the visible-light optical axis. The beam combination lens includes a first light entry surface and a second light entry surface that are arranged opposite to each other and respectively face a visible light signal incidence direction and the display module. A visible light signal of a target field of view passes through the reticle plate to get incident on the first light entry surface, and is then transmitted to the magnification variation lens set. The reticle plate, the beam combination lens, the magnification variation lens set and the display module are interconnected together to form an integrated lens set that is collectively movable together, in order to realize collective adjustment during a reticle adjusting course.

A diffractive optic reflex sight (DORS) is provided for aiming devices in which a virtual image, such as a reticle, is produced and appears in the distance of a user's view when looking through the reflex sight. A light source illuminates a diffractive optical element (DOE) that includes a modulation pattern that generates a patterned illuminations corresponding with the virtual image. A reflective image combiner then reflects the patterned illumination so that the virtual image appears in the distance of the viewer's view. The DORS optical design system is mechanically and optically stable for precision aiming across a range of environmental conditions and in different use scenarios or applications including use in rapidly changing temperatures, varying light conditions, and a wide range of user proficiencies. The DORS optical design system is a readily manufacturable aiming and sighting device for a wide range of applications from handguns to astronomical telescopes.

Systems and methods are described which provide a film through scope camera mount including a housing that includes a beam splitter, first and second mirrors, and a sensor. The camera mount system may receive an input optical signal from a first direction; split the input optical signal using the beam splitter such that a first portion of the input optical signal may be communicated out of the camera mount system in a second direction and a second portion of the input optical signal may be reflected lateral to the first direction; reflect the reflected signal vertically using the first mirror; reflect the vertically reflected signal in a second lateral direction using the second mirror; and receive the signal reflected by the second mirror in the sensor, which may comprise a visible light sensor and/or an infrared sensor.
