Title: Thomas Francis Strelchun: Innovator in Optical Measurement Technologies

Introduction

Thomas Francis Strelchun is a notable inventor based in Mertztown, PA (US). He has made significant contributions to the field of optical measurement technologies, holding a total of 3 patents. His work focuses on enhancing the accuracy and functionality of optical spectrum analyzers and phase-locked loops.

Latest Patents

One of his latest patents is an "Optical spectrum analyzer wavelength non-linearity measurement system." This innovative measurement tool assesses the wavelength linearity of an optical spectrum analyzer by utilizing the linear skirt slope region of the included resolution bandwidth filter. The system sweeps the input wavelength from a predetermined start value to a predetermined stop value while recording the associated amplitude. To ensure accuracy, the insertion loss associated with the system is first determined and removed from the recorded amplitude values. By knowing the skirt slope and the measured amplitudes, the wavelength offset can be accurately determined.

Another significant patent is for "Methods and devices for testing the operation of counters used in phase-locked loops." This invention addresses intermittent miscounts generated by counters in a phase-locked loop (PLL). It precisely measures these miscounts by detecting changes to a predetermined waveform, such as a sawtooth waveform. The setup employs two separate signal generators feeding different frequencies into the MAIN and REF counters of a PLL. By offsetting the frequencies slightly and integrating an output, the predetermined waveform is generated, allowing for the detection of miscounts by comparing them to theoretically predicted waveforms.
