    摘要: The present invention relates to an optical navigation system for determining at least one parameter of a pose, which includes the position and orientation of an object in an environment. The optical navigation system uses a number of beacons affixed at known locations in the environment to provide electromagnetic radiation in a sequenced pattern. An on-board optic images the radiation from the beacons onto an on-board centroid sensing device to obtain an imaged distribution of the radiation on the on-board centroid sensing device. The centroid sensing device- determines the centroid of the imaged distribution and provides centroid information to a navigation unit for determining at least one parameter of the pose of the object from the centroid. The navigation system is particularly well-suited for navigating hand-held objects.

    摘要: An elongate object (10) optically determines at least one of its orientation parameters relative to a plane surface. A probe radiation beam (16) is directed from the object (22) at various angles s to various locations on the plane, where the angle s is a periodic function of time. Two angularly-selective radiation detectors oriented at fixed angles t 1 and t 2 sense scattered portions (18) of the beam from two locations (22) and (24) at two corresponding times. The orientation parameter is computed from a time difference ?t=t 2 -t 2 between the two times.

    摘要: A solid catadioptric lens (100) with a single viewpoint has a spherical refractive surface (102) with a center C on an optical axis of the lens. An ellipsoidal reflective surface (104) of the lens faces the spherical refractive surface such that a first focus F 1 of the ellipsoidal reflective surface is coincident with the center C of the spherical refractive surface. Furthermore, the lens has a shaping surface (106) facing the ellipsoidal reflective surface for shaping a light that passes the single viewpoint. The shaping surface can be refractive, reflective or semi-transparent and its shape can be ellipsoidal with its first focus F 1 ' coincident with the second focus F 2 of the ellipsoidal reflective surface. The single viewpoint of the lens is at the center C of the spherical reflective surface and is enforced with an aperture (112) that can be positioned at various points inside, on a surface or even outside the lens, depending on the type of shaping surface chosen.

    摘要: An apparatus and method for determining an inclination angle θ between an axis of an elongate object such as a cane, a pointer or a jotting implement such as a pen, pencil, stylus or the like and a normal to a plane surface at times when a tip of the elongate object is contacting that plane surface. The apparatus has an emitter mounted on the object for illuminating the plane surface with a probe radiation at an angle σ with respect to the axis of the object. The apparatus also has a detector mounted on the elongate object for detecting a radiation characteristic of a scattered portion of the probe radiation returning from the plane surface and a computing unit for deriving the inclination angle θ from the radiation characteristic. A scanning arrangement, such as a uniaxial or biaxial scanner, or a light guiding optic can be used for varying angle σ, and the probe radiation can be emitted in the form of a scan beam. Preferably, the emitter and detector of the scattered portion of the probe radiation are integrated and the scattered portion of the probe radiation whose characteristic is being measured is the back-scattered portion. The radiation characteristic detected by the detector can be the intensity, polarization, time-of-flight or any combination thereof.
