Title: Innovations of Frederic P Fischer
Introduction
Frederic P Fischer is an accomplished inventor based in Williamsville, NY (US). He holds two patents that showcase his expertise in precision measurement and image enhancement technologies. His work has significantly contributed to advancements in various fields.
Latest Patents
One of Fischer's latest patents is focused on the measurement of fiber diameters with high precision. This invention provides methods for measuring the diameters of transparent filaments with remarkable accuracy, achieving RMS standard deviations of less than 0.02 microns. The methods utilize a beam of laser light to illuminate the filament, producing a far-field interference pattern. By performing a fast Fourier transform (FFT) on the interference data, a coarse estimate of the average spatial frequency is obtained. Subsequently, discrete sequence Fourier transforms (DSFTs) are conducted to achieve the desired high precision estimate. This innovative approach allows for real-time measurements on moving optical waveguide fibers at rates exceeding 500 measurements per second.
Another significant patent by Fischer is a method and apparatus for transmitting facsimiles over telephone lines. This invention enhances the quality and transmission speed of fingerprint facsimiles by employing image enhancement techniques prior to transmission. Utilizing a multi-element photodetector array, Fischer's method processes signals from the array's components simultaneously, producing a binary video output that indicates whether the center of the scan is on a ridge or a valley portion of the fingerprint.
