摘要： An adapter and method for through the lens (TTL) laser range sensor probes enables use of a TTL probe of a given exit pupil size to be used with a shared objective lens requiring a entrance pupil size, as entered from the laser range sensor, that is different from the TTL probe exit pupil size. Embodiments of the adapter include optics, such as a first lens and a resolving second lens that expand or contract the TTL laser radiation depending on whether the first lens is a diverging, a negative focal length lens, or a converging, positive focal length lens, and the second lens is converging or diverging, respectively, in a Galilean arrangement. Embodiments also provide a Keplerian arrangement, can function with non-collimated radiation, and can include mirrors to yield a more compact adapter. Additional embodiments include at least one adjustable lens element between the first and second lenses, the at least one adjustable lens element being connected to an actuator for movement along the optical path. The adapter can be arranged in a folded configuration in which mirrors are used to form a more compact adapter.

摘要： A method of edge detection with an optical measuring machine including aligning a test object with a lens system having a variable size aperture, wherein the lens system is operable to form an image of the test object on a digital sensor having an array of addressable pixels, and wherein the variable size aperture is operable to image points of the test object on the digital sensor at different spot sizes. Setting the variable size aperture to a first size and binning contiguous clusters of the addressable pixels into image pixels having a first size in accordance with the number of addressable pixels within each of the image pixels. Identifying contrast variations of the test object imaged onto the digital detector over a number of image pixels at the variable aperture first size, whereby an area of the test object is imaged at a first effective magnification.

摘要： An optical imaging system for a dimensional measuring machine including a digital sensor having an array of addressable pixels, a lens system that provides for forming an image of a test object on the digital sensor, and a variable size aperture of the lens that changes an f-number of the lens system for imaging points of the test object on the digital sensor at different spot sizes. An aperture controller varies the aperture size. An image controller groups contiguous clusters of one or more of the pixels having a common output such that the number of pixels within each of the clusters having a common output can be varied. A magnification controller that works in conjunction with the aperture controller and the image controller provides for (a) increasing the number of pixels within each of the clusters having a common output in accordance with an increase in the spot sizes at which points of the test object are imaged and (b) decreasing the number of pixels within each of the clusters having a common output in accordance with a decrease in the spot sizes at which points of the test object are imaged.

摘要： A probe for an optical measurement system includes a probe body arranged to be adjustably mounted in a measuring machine for optically measuring a test object. A polarizing fiber optically coupled within the probe body transmits a source beam having an instantaneous or sequentially established bandwidth spanning a range of wavelengths to the probe body and also transmits a measurement beam from the probe body toward a detector. An adjustable beam manipulator is provided for angularly redistributing the reference beam along the reference arm.

摘要： An optical measuring system for a measuring machine includes at least two scanning devices for intermittently moving through alternately timed sequences of static measuring positions at which a measuring beam is directed to and from a test object. An optical switch selectively routes the measuring beam through any one of the scanning devices that has settled into one of the static measuring positions.

摘要： A counterbalance and drive system for a machine slide mechanism includes a counterbalance system having a first flexible connector suspended from a machine mount and interconnecting a slide mechanism and a counterweight and a drive system having a second flexible connector suspended from the machine mount and interconnecting the slide mechanism and the counterweight. The drive system includes both a drive motor operatively engaged along a length of the second flexible connector for vertically displacing the slide mechanism and a compliant connector operating within a limited range of compliance that imparts a regulated amount of tension along at least a portion of the length of the second flexible connector between the engagement of the drive motor and the counterweight.

摘要： A method of determining whether a part satisfies tolerance criteria includes making a multiplicity of measurements of the part, reducing the number of measured points to a number of boundary points that define a boundary within which all measured points are encompassed and comparing the boundary to a tolerance limit of a normal surface to determine whether the part conforms to the tolerance.
