Title: Innovations of Matthew P Frazer
Introduction
Matthew P Frazer is an accomplished inventor based in Plymouth, MI (US). He holds three patents that showcase his expertise in optical measurement systems and calibration methods. His work has significantly contributed to advancements in three-dimensional surface topography measurement.
Latest Patents
One of his latest patents is an "Optical method and system for measuring three-dimensional surface topography of an object having a surface contour." This invention utilizes interferometric methods to provide high-resolution contour measurements. It employs co-sight detector technology to capture at least three independent images of the same object location, each with a known fringe pattern. The simultaneous collection of these images allows for high-speed 3D data generation, overcoming previous limitations related to sample motion and vibration. The system can be constructed without moving parts, resulting in a more cost-effective assembly with improved repeatability.
Another notable patent is the "Method for calibrating a tilt inspection system and reference disk." This method involves a mirror disk attached to a rotatable member, allowing for precise tilt angle calibration. As the reference disk rotates, a beam of light reflects off the mirror disk to a position-sensitive detector, creating a circle on its face. The calibration process involves acquiring PSD voltage data, analyzing it to locate a reference marker, fitting the data to sine functions, and computing tilt transformations. This approach minimizes operator error and reduces the effects of system noise.
