Latest Patents

Richard W. Swinford holds a patent for an invention titled "Automated minimization of optical path difference and reference mirror focus in white-light interference microscope objective." This invention focuses on determining the average fringe contrast through PSI measurements during large translations of the reference optics and mirror. The data collected is utilized to minimize the optical path difference (OPD) between the reference and test beam paths. By employing algorithms from conventional vertical scanning interferometry, the position of minimum OPD is identified by locating the maximum average fringe contrast. The automation of this system with a precise translation mechanism eliminates operator-to-operator variations, significantly improving the precision of OPD minimization. Additionally, the invention calculates the optimal focal position of the reference mirror simultaneously, enhancing the overall effectiveness of the microscopy process.
