Latest Patents
One of his latest patents is titled "Mixed frequency and amplitude modulated fiber optic heterodyne." This invention describes a method and apparatus for a precision optical distance measuring device that can determine both external and internal target geometries. The device utilizes a frequency modulated laser diode, which splits the beam into reference and target beams. A closed-loop control system modulates the amplitude of the reference beam to maintain a balance between the power in the target return beam and the reference beam. This allows the sensor to operate effectively with targets of varying reflectivity and across a broad range of angles. The interference of the reference and target return beams at a detector produces a beat wave, with the beat frequency being linearly related to the distance of the target from the sensor, thus providing high precision in measurement.
Another significant patent is the "Laser scanning method and apparatus for rapid precision measurement." This invention features a non-contact laser-based sensor guided by a precision mechanical system that scans a thread form, producing digitized images. These images are analyzed to derive quantitative information about thread characteristics, including pitch, lead, root radius, flank angle, surface roughness, helix variation, and pitch diameter. The system can be mounted on thread-making machines for on-line monitoring and control of the thread forming process.
