A method and apparatus for photogrammetrically determining a six degree of freedom spatial relationship between a first object and a second object is disclosed. In one embodiment, the method comprises photogrammetrically determining a first orientation of the first object relative to the second object, photogrammetrically determining a second orientation of the second object relative to the first object, and determining the six degree of freedom spatial relationship between the first object and the second object from the photogrammetrically determined first orientation of the first object relative to the second object and the photogrammetrically determined second orientation of the second object relative to the first object.

A method and apparatus comprising a group of passive sensor systems, an active sensor system, and a processor unit. The group of passive sensor systems is configured to generate first sensor information from light in an environment around the group of passive sensor systems. The active sensor system is configured to send signals, receive responses from the signals, and generate second sensor information from the responses. The processor unit is configured to control the active sensor system to send the signals in a direction toward an object using the first sensor information and generate information about the object using the second sensor information.

A laser metrology system may include a modulated measurement beam, a beam splitter for splitting the measurement beam into a local oscillator beam and a transmitted beam, an optical assembly for projecting the transmitted beam to a measured area on a surface of a target structure and for receiving a reflected beam from the measured area, a beam combiner for combining the reflected beam and the local oscillator beam into a detection beam, a detector for processing the detection beam, the detector including a micro-lens for projecting the detection beam, a photodetector for carrying out coherent detection of the detection beam and detector electronics in communication with the photodetector for generating informational data from the detection beam, and a range processor for computing dimensional data about the measured area from the informational data.

Laser metrology system and method

Systems and methods for measuring a surface of an object. The system, in one embodiment, includes a laser projector device mounted at a fixed location relative to an object being formed by a fabrication process, and a videogrammetry device mounted at another fixed location relative to the object. The laser projector device includes a laser element mounted on a two-axis gimbal assembly, and the gimbal assembly directs laser beams from the laser element onto target points on a surface of the object. The laser projector device measures angles of the laser beams to the target points, while the videogrammetry device simultaneously performs measurements of the target points by capturing video images of the laser beams reflecting off of the target points. A controller processes the measurements from the laser projector device and the videogrammetry device to calculate x, y, z coordinates of the target points in a 3D coordinate system.

A non-contact biometric sensing device is described. The device includes a processing device, a user interface communicatively coupled to the processing device, a display communicatively coupled to the processing device, a laser doppler vibrometer sensor communicatively coupled to the processing device, and an infrared camera communicatively coupled to the processing device. The processing device is programmed to utilize mechanical motion data received from the laser doppler vibrometer sensor and thermal distributions data from the infrared camera to calculate biometric data, when signals originating from the laser doppler vibrometer sensor and the infrared camera are reflected back towards the device from a target.

Systems and methods for non-contact biometric sensing

Systems and methods to control projection of a pattern are provided. A particular method includes receiving first three-dimensional coordinates that specify one or more locations on a surface of a workpiece where the one or more locations correspond to a part definition to be projected onto the surface. The method also includes computing scan angles for a scanning system based on the first three-dimensional coordinates. The scan angles specify angles used by the scanning system to direct a beam of light to project the part definition onto the surface. The method also includes sending control signals to the scanning system based on the scan angles.

Controlling a projected pattern

Systems and methods are provided for targetless optical measurement and optical information projection. A non-contact optical measurement device is provided for determining at least one of position and orientation of a workpiece. A projector is provided for projecting a part definition on the workpiece. Advantageously, beams from the non-contact optical measurement device and the projector pass through common optics.

An angle absolute encoder comprises a code rod encoded with code marks configured in segments, such that each successive segment has an increasing number of code marks, arranged at an angle to the rotation axis depending on the number of code marks in each segment. The angle of the code mark is determined by the number of code marks in the respective segment, the width of the segment parallel to the rotation axis of the code rod and the radius of the code rod. The angular resolution increases according to the number of code marks in each segment. Light is reflected from or transmitted through the code marks and detected by a light detector to determine absolute angle position.
