An optical assembly for three-dimensional image capture includes first and second optical channels that are fixed with respect to one another. Each channel is configured to direct light onto at least a portion of an image sensor. The first and second optical channels each include an aperture for receiving the light, an objective lens for focusing the light into an intermediate image on an intermediate image plane, and an eyepiece lens for collimating the intermediate image.

Long focal length monocular 3D imager

A folded optical system includes a powered optical element, at least one folding mirror and an aperture and defines an optical path through the optical system. The powered optical element, the at least one folding mirror and the aperture are configured to fold the optical path at the aperture, thereby providing a compact optical system. The optical system may include an optical block that totally internally reflects the optical signal at the aperture. Optionally or alternatively, discrete optical components may be used, such as an aperture made of a conventional material or a metamaterial, an off-axis parabolic mirror or lens and one or more folding mirrors. Some embodiments include a wavelength dispersive element, so as to implement a spectrometer.

Aperture-fold imaging system

A device and method for selectively illuminating and designating multiple targets in the air or on the ground simultaneously. The device comprises a light source, a switching array and a ball lens. Light from the light source is routed through the switching array, which can addressably output multiple light beams simultaneously. The light beams from the switching array illuminate the backside of a low F-number ball lens. The ball lens creates highly collimated output beams independently (and simultaneously) from any of the output source points of the switching array. These output beams can be used to simultaneously designate multiple targets. When the target illuminating device includes an optional detector array, light scattered from targets can be refracted by the balls lens to impinge on the detector array. Signals from the detector array representing the received light beams can be used for target imaging.

Multi-target optical designator

A computer input device includes, in one embodiment, at least two accelerometers, at least two gyroscopes, and a processor within a housing. Signals from the accelerometers and the gyroscopes are utilized to determine the relative motion of the computer input device.

Computer input device with inertial instruments

The transformable vehicle comprises a central chassis assembly having first and second distal ends with an axis passing therebetween, a first wheel assembly mounted to the first distal end, and a second wheel assembly mounted to second distal end. A multifunction transformable vehicle comprising at least two configurational states: a stowed state and a transformed state. In the stowed state, the transformable vehicle comprises a compact structure suitable for storage, transport or deployment. During transition from the stowed state to the transformed state, the first and second wheel assemblies move longitudinally outward along the axis to reveal the central chassis assembly.
