Abstract: A system and method for profile measurement based on triangulation involves arrangement of an image acquisition assembly relative to an illumination assembly such that an imaging plane is parallel to a light plane (measurement plane defined by where the light plane impinges on the object), which supports uniform pixel resolution in the imaging plane. The image acquisition assembly includes an imaging sensor having a sensor axis and a lens having a principal axis, wherein the lens axis is offset from the imaging axis.

Abstract: A method is used for imaging applications so that one can simultaneously apply multiple illumination schemes and simultaneously acquire the images, each associated with one of the multiple illumination schemes. The illumination schemes can be, but not limited to, any combination of reflective illumination, transmitive illumination (backlighting), bright field illumination, dark field illumination, diffused illumination, cloudy-day illumination, and structured illumination. The radiation can be in any wavelengths, ranging from sonic waves, ultra sound, radio waves, microwaves, infrared, near infrared, visible light, ultra violet, X-rays, and gamma rays. The radiation of each of the illumination schemes used in an imaging application is modulated (57), that is, affixed with a unique signature. One or more imaging devices (52) can be used to collect the radiating rays simultaneously after the rays interact with the object (66). The image signals are then demodulated (54) and separated into several images, each being associated an illumination scheme, based on the signatures. A preferred embodiment is to use radiation wavelengths of 430 nm, 575 nm or 670 nm as the signatures.

Abstract: An inspection system is used to view an image of the inside diameter (ID) of an engine bearing. The inspection system includes a stationary line scan camera, a pivoting mirror, a scanning mirror and a stationary mount. The engine bearing is placed in the stationary mount such that the bearing remains motionless throughout the entire scanning process. The light line generator produces a light line that initially contacts a beam splitter. The beam splitter then guides the light line onto the pivoting mirror, which then directs the light line onto one of a pair of stationary mirrors and then finally onto the scanning mirror. The scanning mirror will sweep the light line across a portion of the engine bearing ID surface. The light line will generate reflected images of the ID surface. These reflected images will return along the light line's path; however, instead of being directed back into the light line generator by the beam splitter, the reflected images will pass through the beam splitter. Once the reflected images pass through the beam splitter, they will journey through the lens and into the stationary line scan camera. From the stationary line camera, the reflected images can be viewed on a monitor and recorded for future use.
