Abstract: A high-intensity light source configuration has a long lifetime and can be modulated at a high rate. The configuration includes a movable member mounted to an actuator; a light-emitting phosphor region associated with the movable member; an input light source that illuminates the light-emitting phosphor region at a spot that is fixed relative to an emitted light output region; and a light source controller controlling the movable member actuator and the input light source. The input light source (e.g., laser) provides high-intensity input light to the illuminated spot, causing the light-emitting phosphor region to emit high-intensity output light. The light-emitting phosphor region is moved relative to the illuminated spot so as to reduce optical quenching and photobleaching, to thereby extend the life of the light source configuration. The phosphor region may emit broadband light and/or may include respective sub-regions having phosphors that emit respective peak wavelengths.

Abstract: A phosphor point source element comprises a disk substrate and light emitting phosphor particles arranged on the substrate to provide a circular operational track having a desirable tightly packed particle arrangement adjacent to a flat operational surface of an operational track region. The operational track region is rotated while illuminated to provide a high intensity point source of radiation. The tightly packed particle arrangement may be achieved by spinning the phosphor particles in a cavity between a fabrication plate and the substrate, to compress the phosphor against the fabrication plate at the periphery of the cavity, or by mechanically compressing the phosphor. An adhesive binding agent may permeate the phosphor particles and be cured to maintain the tightly packed arrangement. A window element may support and/or protect the operational surface, in some embodiments.

Abstract: A probe control interface is provided for a structured light non-contact coordinate measuring machine probe. Portions of a video control signal for controlling the grey level of selected rows of pixels of a spatial light modulator of the probe can be decoded into control signals for additional probe components or functions that have been added to increase the measuring capabilities or versatility of the non-contact probe. By providing the additional probe component control signals in this manner, a versatile structured light non-contact probe system can be made compatible with a standard probe head autojoint system (e.g. a Renishaw™ type system), thus allowing the probe to be automatically exchanged with other standard probes and allowing existing systems to use the non-contact probe more easily. Various aspects of the probe control interface allow for relatively simple, compact, lightweight and robust implementation.

Abstract: A multi-range non-contact probe is provided which performs approximate range-finding measurement functions in addition to more precise structured light measurement functions. The probe is compatible with a probe control interface which allows advanced measuring capabilities and functions to be used with a probe head system that provides a limited number of wired connections. A laser beam of the probe is directed along a first optical path during a first period for providing structured light measurement functions and is directed along a second optical path for a second time period range finding functions. A single beam modification element having at least first and second portions with different types of optical characteristics is moved to output the laser beam from the first portion along the first optical path and then to output the laser beam from the second portion along the second optical path.

Abstract: A hand-size structured-light three-dimensional metrology imaging system and method. Laser illumination stripes are scanned across a workpiece surface for obtaining z-height and x-coordinate information. A Scheimpflug configuration is used. Utilizing this configuration, a laser illumination stripe across a raised workpiece portion will be shown in a contour image at the image sensor in a focused manner, such that the offsets along the contour image line due to the raised portions of the workpiece surface can be accurately converted to a z-height measurement. The y-axis positions associated with each of the contour images, used for reassembling the information from the contour images into a surface map for the workpiece, may be determined without the need for a position sensor, by including a reference object in the contour images.

Abstract: Various exemplary embodiments may provide systems and methods for strobe illumination of a workpiece. The systems may include an illumination source, an image acquisition device and a control system. The illumination source may emit visible, UV, or near-IR light as a transient flash to the workpiece, the transient flash occurring in response to a lamp trigger. The illumination source may emit the light at an illumination intensity that rises from a begin threshold to a peak and afterwards diminishes to an end threshold during a flash duration. The image acquisition device may capture the light associated with the workpiece for an exposure duration starting from an exposure trigger. The control system may control the illumination source and the image acquisition device to synchronize the lamp trigger so that the exposure duration ends during the flash duration, such that a remaining portion of the flash does not affect the image exposure.

Abstract: Systems and methods for identifying an interchangeable lens in a vision system having a controllable light source, a camera, and the lens to be identified. Light provided by the light source is transferred to the camera by the lens to be identified. The amount of light transferred to the camera for a particular reference configuration of the vision system depends distinguishably on the characteristics of the lens to be identified. A camera output is measured for a desired light source setting and the desired light source setting and associated measured camera output are compared with stored lens identification calibration data. The stored lens identification calibration data is obtained by measuring the camera output for a plurality of lenses using a plurality of light source settings. In various exemplary embodiments, the light transferred from the light source to the camera is reflected and/or backscattered light from the lens to be identified.

Abstract: An illumination technique is provided that adjusts the respective light intensities of each of a plurality of light sources that are strobed at desirable consistent intensities by adjusting a respective light pulse pattern for each respective light source. All the light sources are controlled to illuminate an object throughout a strobe duration period. The light pulse patterns may be micro-strobed light pulse patterns, formed by a variety of methods. The illumination technique is usable to preserve the general shape of the edge intensity profile on an object, and allow precision edge position measurements, regardless of whether the object is moving or not during image acquisition.

Abstract: Auto focus systems and methods for a machine vision metrology and inspection system provide high speed and high precision auto focusing, while using relatively low-cost and flexible hardware. One aspect of various embodiments of the invention is that the portion of an image frame that is output by a camera is minimized for auto focus images, based on a reduced readout pixel set determined in conjunction with a desired region of interest. The reduced readout pixel set allows a maximized image acquisition rate, which in turn allows faster motion between auto focus image acquisition positions to achieve a desired auto focus precision at a corresponding auto focus execution speed that is approximately optimized in relation to a particular region of interest. In various embodiments, strobe illumination is used to further improve auto focus speed and accuracy. A method is provided for adapting and programming the various associated auto focus control parameters.
