Abstract: An oximeter device has an ergonomically shaped enclosure that allows a user to comfortably grip and use the device during handheld operation. A sensor tip can be easily placed evenly on the tissue surface, so that all sources and detectors are directly on the tissue with even pressure. This allows for more consistent and accurate results. The user can easily move the device from one position to another and take numerous measurements. The user will have a wide, unobstructed view of the tissue because of the tip's small size, angle of display, and the grip and fingers are positioned away from the tip. Components housed by the enclosure are arranged to give the device a balanced weighting while in the hand. The device can be used for long periods at a time without fatigue.

Abstract: An optical system includes a splitting optic configured to receive a light beam from a light source and form a set of light bands radiating from the optical system at predetermined angles relative to illuminate a scene. The optical system further includes a lens configured to project a field of view of the scene into a two-dimensional format. The optical system further includes an optical sensor arranged offset from the central axis of the lens to capture a segment of the field of view projected by the lens.

Abstract: An optical apparatus includes a substrate that is configured to redirect a predetermined percentage of an input light beam at a plurality of angles to form a set of output beams at each of the angles such that light beams redirected at each of the angles cooperate to form bands of light at a range of predetermined distances from the optical apparatus.

Abstract: A spreading optics system distributes electromagnetic (EM) waves emitted by an emitter having an emission vector. The spreading optics system includes reflective surfaces. The reflective surfaces include concave first reflector having a concave cross section in a plane substantially perpendicular the emission vector. The reflective surfaces further include a convex second reflector arranged further from the emitter than the concave first reflector. The convex second reflector has a convex cross section in a second plane substantially parallel the first plane. The reflective surfaces are configured to divergently redirect the EM waves into a vector fan at a predetermined angle relative to the emission vector.

Abstract: A panoramic annular lens projects a spherical field of view onto a two-dimensional annular format. The panoramic annular lens includes a body, a first refractive surface configured to refract input light rays to obtain first refracted light rays, a first reflective surface configured to reflect the first refracted light rays to obtain first reflected light rays, a second reflective surface configured to reflect the first reflected light rays to obtain second reflected light rays, and a second refractive surface configured to refract the second reflected light rays to obtain output light rays in the two-dimensional annular format. The second refractive surface is externally concave.

Abstract: A sensing method, including: emitting a signal beam; sampling the reflected signal at a sensor with a field of view larger than the signal beam; and determining a surface parameter based on the bright and dark regions associated with the sampled signal.
