A method and apparatus for optically determining the dimension of part surfaces. Particular embodiments describe optical triangulation based coordinate measurement machines capable of accurate measurement of complex surfaces, such as gear teeth and turbine blades. Other embodiments provide highly useful sensors for robot guidance and related purposes. Up to 5 axis sensing capability is provided on surfaces of widely varying form.

Method and apparatus for electro-optically determining the dimension, location and attitude of objects

A method and apparatus for positioning a member in a desired position relative to a surface of an object including providing positioning means for positioning the member, sensing the attitude of the object surface relative to the member or the positioning means using a non-contact sensing means, the attitude being sensed in at least one plane normal to the object surface, and controlling the positioning means using data from the sensing means to position the member at a desired attitude relative to the surface of the object.

Method and apparatus for positioning a member relative to an object

Method and apparatus for electro-optically determining the dimension,

The invention provides a method and apparatus for positioning a member in a desired attitude relative to a surface of an object including, providing a positioning means for positioning the member, providing a non-contact sensor attached to the positioning means, using the sensor, sensing the attitude of the surface of the object in at least two planes, and controlling the positioning means to position the member at a desired attitude relative to the surface of the object.

Method and apparatus for positioning a member in a desired attitude

A method and apparatus for control of a detector array based imaging system which includes analyzing the output of a photodetector array and modifying or controlling a photodetector array light gathering related variable based on the analysis. In particular, one embodiment of the invention involves temporarily storing the image data from the photodetector array and modifying one of the scan clock rate or the scan clock rate within a scan of the photodetector array based on an analysis of the stored data to optimize the light gathering of the image system. A further embodiment of the invention involves controlling a light gathering related photodetector array variable and an illumination source variable based on an analysis of the output of the photodetector array.

Method and apparatus for control of a detector array based imaging

Method and apparatus for imaging an object illuminated with light onto a photodetector array including a microcomputer for controlling the light gathering of the photodetector array by varying the amount of light reflected onto the photodetector array and by varying a photodetector array variable in response to the output of the photodetector array. In one embodiment, the amount of light reflected onto the photodetector array is varied by modifying either the time the light is reflected onto the array or the power of the light reflected onto the array.
