A reticle adjusting structure includes a reticle plate, a beam combination lens, and a relay lens assembly 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 of the beam combination lens, and is then transmitted to the relay lens assembly. The reticle plate, the beam combination lens, the relay lens assembly 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.

Hyperspectral imaging sensors that can readily switch between multiple common aperture imagers, and are more compact and lightweight than previous hyperspectral sensor designs.

An endoscope or other endoscopic instrument is provided with multiple image sensors incorporated into the distal tip, each capturing a portion of the image provided from an optical imaging system. The output from the multiple sensors is combined and manipulated into a single high resolution image which can then be displayed to the user. A virtual horizon rotation feature is also provided which can rotate a displayed image within a combined field of view including data from the multiple image sensors. Various light directing element designs are provided to direct image light to the multiple sensors.
