摘要： 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.

摘要： A micro light interface assembly for a microscopic machine vision inspection system includes a micro light assembly. The micro light assembly provides addressable light emitting elements arranged around the periphery of an aperture having an aperture dimension DAPMIN that is smaller than a barrel dimension DBAR of the inspection system objective lens. The aperture may be located along the optical axis and within the working distance of the objective lens such that the light emitting elements are closely arranged around a field of view. The micro light interface assembly may be held and operated through a connection element that may be used for the interchanging the micro light interface assembly with a touch probe, in some embodiments.

摘要： The repeatability of strobe illumination for image exposure is improved over a wide dynamic range in a machine vision system wherein a relationship between a camera integration period and a pulse duration of a strobe light generator control the effective exposure of a camera image during a timing overlap between a beginning of the camera integration period and an end of the pulse duration. To avoid noise in the illumination, the illumination pulse duration may start, the camera integration period may begin after a delay relative to that start and not later than the end of the pulse duration, the pulse duration may end, and the camera integration period may end not earlier than the end of the pulse duration. The timing overlap may also be synchronized with a periodic ripple component in the strobe illumination, to provide improved repeatability.

摘要： 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.

摘要： 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.

摘要： Systems and methods for operating a vision system to provide a desired illumination wavelength for an inspection operation on workpiece include illuminating a workpiece using narrowband illumination from a continuously variable filter, and modifying the narrowband illumination and evaluating resulting images until a narrowband illumination is found that reliably supports the inspection operation. The initial narrowband illumination may be based on spectral sensing.
