A method for measuring three-dimensional coordinates of a probe center includes: providing a spherically mounted retroreflector; providing a probe assembly; providing an orientation sensor; providing a coordinate measurement device; placing the spherically mounted retroreflector on the probe head; directing the first beam of light from the coordinate measurement device to the spherically mounted retroreflector; measuring the first distance; measuring the first angle of rotation; measuring the second angle of rotation; measuring the three orientational degrees of freedom based at least in part on information provided by the orientation sensor; calculating the three-dimensional coordinates of the probe center based at least in part on the first distance, the first angle of rotation, the second angle of rotation, and the three orientational degrees of freedom; and storing the three-dimensional coordinates of the probe center.

A marker-tracking system includes an object, a marker illuminating device, a marker sensing device, and a computing device. The object includes a first retroreflective marker having a shape that is substantially defined by two spherical caps of different radii that are disposed substantially concentric in relation to one another. The marker illuminating device substantially illuminates the first retroreflective marker, the marker sensing device detects the illuminated first retroreflective marker and generates first data indicative of the location of the illuminated first retroreflective marker in space, and the computing device processes the first data generated by the marker sensing device to determine a position and/or orientation of the object in space.

In one exemplary embodiment, a system, method and apparatus for increasing the visibility of a garment or article of clothing may be described. This can include an element of a garment which may be functionally or structurally integrated into the garment, such as a heat transfer. The heat transfer can utilize any number of visibility-enhancing elements to increase the visibility of a wearer of a garment having the heat transfer, for example through any combination of reflective elements, retro-reflective elements, and elements formed in various colors.

摘要:
A large clear aperture cat's eye retro-reflector system that improves the optical efficiency by two orders of magnitude over conventional cat's eye retro-reflectors. It achieves this increase by using a wide-angle lens design with a curved focal plane, so the entrance aperture is not limited by the design constraints of a solid glass sphere. Since light reflected from a retro-reflector increases as the fourth power of the reflector aperture, light reflected from the retro-reflector of the present invention is increased by two orders of magnitude as compared to the prior art cat's eye retro-reflector of conventional size. When used as a communication device, the retro-reflector is preferably modulated by a quantum well modulator providing very high speed communication. In preferred embodiments a moving quantum well modulator is placed near the focal plane, where the beam footprint is much smaller than the entrance aperture, effectively allowing a small modulator to modulate a large diameter beam. A tracking system tracks the source of interrogating beams and positions the small modulator to intersect the incoming beam near the focal plane where the beam footprint is very small.

A reflector is provided which includes a resilient member formed of elastomeric material having embedded in at least a portion thereof a plurality of retro-reflective glass beads. At least a portion of the outer surface of the elastomeric material is removed to expose at least a portion of the glass beads thereat. The resilient member can be formed either with or without a base member. The base member can be formed either integrally or non-integrally with the resilient member to serve as a support body for the resilient member. When formed with a base member, at least the distal end of the resilient member has a surface portion of the elastomeric material forming the resilient member removed to expose at least a portion of the glass beads thereat.
