A first transceiver has a beam emitter that generates first coherent beams, and first optics that direct the first coherent beams towards a target and collect radiation reflected from the target. A second transceiver has a beam emitter that generates second coherent beams, a detector, and second optics having an aperture. The second optics directs the second coherent beams towards the target via the aperture, collects radiation reflected from the target via the aperture, and guides a first radiation component of the collected radiation, that corresponds to the first coherent beams, to the detector. The detector generates, from the first radiation component, a signal indicative of an intensity of radiation impinging on the target corresponding to the first coherent beams. A control subsystem is associated with the transceivers and modifies at least one parameter of the first transceiver based on the intensity signal.

An apparatus is disclosed. The apparatus may include a housing detachably coupleable to an end of a sighting device. The housing may include a channel protruding from a side of the housing. The apparatus may include a one-way mirror disposed inside the housing. The one-way mirror may be positioned to allow an image from the sighting device to pass through the one-way mirror and reflect the image from the sighting device through the channel. The apparatus may include a mounting plate coupled to the housing. The mounting plate may include one or more adjustment bars that may be engageable with a visual recording device.

An optical system comprising includes an off-axis folded three mirror anastigmat (TMA) telescope including a primary mirror for receiving energy from a scene. A secondary mirror is aligned to receive reflected energy from the primary mirror. A fold mirror is aligned to receive reflected energy from the secondary mirror. A tertiary mirror is aligned to receive reflected energy from the fold mirror and to direct energy between the secondary mirror and the fold mirror. A beam splitter is aligned to receive energy reflected from the tertiary mirror, to reflect a portion of that energy to a first imaging sensor, and to pass a second portion of that energy to a second imaging sensor.

Certain aspects of a novel weapon sight system combine a direct view, a visible light video view, and an infrared (IR) video view mode. Each of the view modes may be viewed individually or simultaneously with one or more of the other view modes through a single viewing aperture. Further, the one or more view-modes may be provided while providing a bore-sighted reticle superimposed on the selected view. Further, the reticle may be powered separately from the video view electronics enabling use of the reticle regardless of the power status video view electronics.

An accessory that is attachable to a device comprises an image sensor and a beam splitter having a first surface and a second surface. The beam splitter is configured to impinge light upon the first surface, and split the light impinging upon the first surface into at least a first beam, a second beam, and a third beam. The first beam travels from a first opening of the device to a second opening of the device along an optical path when the accessory is attached to the device, the second beam travels from the first surface to the image sensor, and the third beam travels from the second surface to the image sensor or a beam dump.

An endoscope imager includes a system-in-package and a specularly reflective surface. The system-in-package includes (a) a camera module having an imaging lens with an optical axis and (b) an illumination unit. The system-in-package includes (a) a camera module having an imaging lens with an optical axis and (b) an illumination unit configured to emit illumination propagating in a direction away from the imaging lens, the direction having a component parallel to the optical axis. The specularly reflective surface faces the imaging lens and forming an oblique angle with the optical axis, to deflect the illumination toward a scene and deflect light from the scene toward the camera module.
