Periscope assemblies are provided which have a light path that travels in a first plane along the first waveguide, a second plane along the second waveguide that is parallel to the first plane, and along a third plane along the third waveguide that intersects the first plane and the second plane. In some examples the periscope assembly includes first and second carriers comprising respective first and second waveguides and defining respective first and second cavities in which a third carrier comprising a third waveguide is disposed and optionally includes an optical component. In some examples, the cavities are defined in one or more carriers on a mating surface, on a side opposite to the mating surface, or on a side perpendicular to a mating surface.

A nightvision system includes an underlying device that provides output light in a first spectrum. A transparent optical device transmits light in the first spectrum from the underlying device through the transparent optical device. The transparent optical device includes an active area of a semiconductor chip. The active area includes active elements that cause the underlying device to detect light from the underlying device and transparent regions formed in the active area which are transparent to the light in the first spectrum to allow light in the first spectrum to pass through from the underlying device to a user. An image processor processes brightness maps produced using light detected by the first plurality of active elements. A tunable filter array coupled to the image processor filters at least a portion of the input light into the underlying device the underlying device based on brightness map processing.

An optical module (10) is attached in front of an optical outlet (21) of a monostatic or quasi-monostatic laser rangefinder (20), for the purpose of transversely offsetting a laser beam of primary radiation (F) emitted by the optical outlet. In this manner, the risk of damage to an optical sensor (23) of the rangefinder can be avoided.

The present disclosure provides for periscope optical assemblies within interposers that include a bulk material having a first side and a second side opposite to the first side; a first optic defined in the bulk material at a first height in the bulk material along an axis extending between the first second sides; a second optic defined in the bulk material at a second height in the bulk material, different than the first height, along the axis; a first waveguide defined in the bulk material, extending from the first side to the first optic; a second waveguide defined in the bulk material, extending from the second optic to the second side; and a third waveguide defined in the bulk material, extending from the first optic to the second optic.

A periscope-type zooming camera module which requires no voice-coil unit includes a light steering device, a lens unit, a light sensing assembly, and a zooming assembly. The light steering device changes transmission direction of light. The lens unit is arranged to receive light from the light steering device; and the light sensing assembly is arranged to receive light from the lens unit. The zooming assembly merely requires different levels of voltage to zoom in and out, adjusting focal length of the lens unit.

An image offsetting apparatus for producing an offset image pathway and presenting the offset image pathway to a user or an optic, including at least some of a prism element comprising a first reflective surface/refracting face and a second reflective surface/refracting face, wherein the prism element is attached or coupled so as to provide the offset image pathway offset from a direct image pathway between a target object and the user or the optic.

Provided is an adjustable optical assembly (900), including a bearing base (921), a driving mechanism (910), a zoom optical assembly (200), and a compensating optical assembly (300). The driving mechanism (910) includes: a bracket (911) having a bottom end connected to the bearing base (921) and a top end having a top groove (911a) open upwards; guide rods (912, 913) supported on the top groove (911a), the guide rods (912, 913) coinciding with the direction of optical axes of the zoom optical assembly (200) and the compensating optical assembly (300); a zoom bearer (914); a compensating bearer (915); a zoom driving assembly; and a compensating driving assembly. The zoom bearer (914) and the compensating bearer (915) are both mounted on the guide rods (912, 913) and slidable along the guide rods (912, 913). Also provided are a corresponding periscopic optical zoom module and an assembly method therefor. According to the adjustable optical assembly (900), the bracket (911) and the guide rods (912, 913) are disposed on the bearing base (921), thereby effectively ensuring that the moving directions of a zoom group and a compensating group do not deviate from a main optical axis. Moreover, the adjustable optical assembly (900) is compact in structure and convenient to assemble, and facilitates large-scale mass production.
