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.

An interferometric measuring machine includes an exchangeable lens module system for an optical probe. The probe includes a lens body containing the optical apparatus of an interferometer and a lens module containing an objective lens along an object arm of the interferometer that can be exchanged with other lens modules for varying the measuring characteristics of the probe. The lens modules are adapted to accommodate objective lenses having different focal lengths while maintaining a desired optical path length of the object arm of the interferometer.

An optical pen 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 single mode fiber optically coupled within the pen body transmits a source beam having an instantaneous or sequentially established bandwidth spanning a range of wavelengths to the pen body and also transmits a measurement beam from the pen body toward a detector. A combination and configuration of optics within the pen body provides a more compact and efficient optical pen.

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 single mode 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 within the probe body spatially excludes portions of the reference beam over a progression of different size portions from being focused within the acceptance cone of the single mode fiber to more closely balance the intensities of the reflected object beam and the reflected reference beam within the measurement beam.

A profilometer incorporating a partial coherence interferometer directs a beam containing a band of wavelengths along object and reference arms of the interferometer into respective engagements with a test object surface and a reference object surface en route to a spectrometer for measuring a spectrum of the beam. Within the object arm, the test object surface is relatively moved through a range of positions offset from a null position at which optical path lengths of the object and reference arms are equal. Modulation frequencies of the beam spectrum are calculated at a succession of different focus spot positions across the test object surface. Changes in the modulation frequency are interpreted to distinguish between optical path length differences at which the optical path length of the object arm is longer or shorter than the optical path length of the reference arm.

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.

Laser range sensor system optics adapter and method

A distance detecting arrangement employs at least two sensors having different ranges and resolutions of operation. Embodiments disclosed contemplate at least four modes of operation. In a first mode, only one sensor is employed. In a second mode, a longer range and lower resolution sensor is employed until a threshold value of distance is reached, at which point a shorter range and higher resolution sensor is employed. In a third mode, both the longer range and shorter range sensors are employed simultaneously. In a fourth mode, a low resolution profile is used to rescan the object with the high resolution sensor to provide a high resolution profile measurement. Embodiments facilitate the method disclosed by including a beam redirecting apparatus and preferably include a servo position system that can move the sensors and the object relative to each other.

Dual resolution, dual range sensor system and method

A partial coherence interferometer incorporates a focusing system for resolving measurement ambiguities. A focus-sensing beam is directed through a common objective with the measurement beam of the interferometer for conveying the beams to and from a test surface. An unambiguous measuring range is equated to a predetermined range of focusing errors.
