摘要： An apparatus and method employing principles of stereo vision for determining one or more orientation parameters and especially the second and third Euler angles θ, ψ of an elongate object whose tip is contacting a surface at a contact point. The apparatus has a projector mounted on the elongate object for illuminating the surface with a probe radiation in a known pattern from a first point of view and a detector mounted on the elongate object for detecting a scattered portion of the probe radiation returning from the surface to the elongate object from a second point of view. The orientation parameters are determined from a difference between the projected and detected probe radiation such as the difference between the shape of the feature produced by the projected probe radiation and the shape of the feature detected by the detector. The pattern of probe radiation is chosen to provide information for determination of the one or more orientation parameters and can include asymmetric patterns such as lines, ellipses, rectangles, polygons or the symmetric cases including circles, squares and regular polygons. To produce the patterns the projector can use a scanning arrangement or a structured light optic such as a holographic, diffractive, refractive or reflective element and any combinations thereof. The apparatus is suitable for determining the orientation of a jotting implement such as a pen, pencil or stylus.

摘要： A method and apparatus for determining a pose of an elongate object and an absolute position of its tip while the tip is in contact with a plane surface having invariant features. The surface and features are illuminated with a probe radiation and a scattered portion, e.g., the back-scattered portion, of the probe radiation returning from the plane surface and the feature to the elongate object at an angle τ with respect to an axis of the object is detected. The pose is derived from a response of the scattered portion to the surface and the features and the absolute position of the tip on the surface is obtained from the pose and knowledge about the feature. The probe radiation can be directed from the object to the surface at an angle σ to the axis of the object in the form of a scan beam. The scan beam can be made to follow a scan pattern with the aid of a scanning arrangement with one or more arms and one or more uniaxial or biaxial scanners. Angle τ can also be varied, e.g., with the aid of a separate or the same scanning arrangement as used to direct probe radiation to the surface. The object can be a pointer, a robotic arm, a cane or a jotting implement such as a pen, and the features can be edges, micro-structure or macro-structure belonging to, deposited on or attached to the surface which the tip of the object is contacting.

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.

摘要： An elongate object optically determines at least one of its orientation parameters relative to a plane surface. A probe radiation beam is directed from the object at various angles σ to various locations on the plane, where the angle σ is a periodic function of time. Two angularly-selective radiation detectors oriented at fixed angles τ1 and τ2 sense scattered portions of the beam from two locations a two corresponding times. The orientation parameter is computed from a time difference Δt=t2−t1 between the two times.

摘要： An apparatus and a method are disclosed for optically determining a distance r to a feature from an origin or a center. The apparatus uses a beam generation unit for launching a reference beam on a reference path and a first beam on a first path. The center from which distance r is determined is selected such that it is along a line of the reference path and not along a line of the first path. Alternatively, the center can be chosen not to lie along a line of the reference path. A rotation mechanism rotates the reference path and the first path about the center such that the reference beam moves over the feature at a reference time tr and the first beam moves over the feature at a first time t1. A determination unit determines distance r between the center and the feature from an angular velocity ω of the reference beam over the feature and from times tr, t1.

摘要： An apparatus uses reflectance spectrophotometry to characterize a sample having any number of thin films. The apparatus uses two toroidal mirrors in an optical relay to direct light reflected by the sample to a spectroscopic device. A computer then analyzes the reflected spectrum to characterize the optical properties of the sample. The optical relay allows a range of angles of reflection from the sample, and has no chromatic aberration. The optical relay is also arranged so that the non-chromatic aberration is minimized. For polarization-based measurements polarizing elements can be used in the apparatus and the spectroscopic device can be a spectroscopic ellipsometer. The sample is mounted on a movable stage so that different areas of the sample may be characterized. Furthermore, a deflector and a viewer are used to allow the operator of the apparatus to view the region of the sample under study.

The optical system includes an objective lens that has a collecting end that is positioned proximate to a sample and configured to receive optical signals therefrom. The optical system also includes a removable path compensator that is configured to be located at an imaging position between the collecting end of the objective lens and the sample. The path compensator adjusts an optical path of the light emissions when in the imaging position. Also, the optical system includes a transfer device that is configured to move the path compensator. The transfer device locates the path compensator at the imaging position for a first imaging session and removes the path compensator from the imaging position for a second imaging session.
