Latest Patents
One of Knowlden's latest patents is the "Pulsed Source Scanning Interferometer." This invention utilizes a pulsed light source in conjunction with a ramping scanning mechanism for phase-shift and vertical-scanning interferometry. The design ensures that the pulse length and scanning velocity are optimized to minimize changes in optical path difference (OPD) during the pulse. This innovation allows for improved signal utilization during phase-shifting and vertical-scanning interferometry by producing minimal phase shifts that result in negligible loss of fringe modulation.
Another significant patent is the "Method and Apparatus for Correcting Shifts Between a Reference Focal." This invention involves adding structural components to an interferometric objective to counteract the effects of temperature variations. The components are strategically mounted to ensure that the thermal response of the assembly is a linear combination of each component's response. This design effectively minimizes shifts between the reference mirror and focal point in response to temperature changes.
