Title: Innovations of Charles C Harb

Introduction

Charles C Harb is an accomplished inventor based in Sunnyvale, CA. He holds a total of 4 patents that showcase his expertise in optical technology. His work has significantly contributed to advancements in wavelength detection and laser absorption spectroscopy.

Latest Patents

One of his latest patents is an optical beamsplitter for a polarization insensitive wavelength detector. This invention describes a wavelength detector that includes a beamsplitter with a wedged back surface. This design allows the incoming optical signal to be reflected into two paths. Each path contains filters, at least one of which varies with the wavelength of the optical signal. The filtered light is then detected by a photodetector, and the output electrical signals are log amplified. These log amplified signals are applied to a difference amplifier, whose output indicates the wavelength or polarization of the incident optical signal.

Another notable patent is a laser-based spectrometer designed for use with pulsed and unstable wavelength laser sources. This laser absorption spectrometer measures absorption spectra and includes a wavelength sensor capable of measuring the average wavelength of laser pulses on a pulse-by-pulse basis. It can also measure internal wavelength variations of laser pulses. This technology is particularly useful for sensitive measurements of absorption spectra, even when there are variations in the average wavelength of the pulses.
