Title: Innovations by John D. Sonderman: A Profile of an Inventor

Introduction

John D. Sonderman, an inventive spirit from Santa Rosa, California, holds a notable portfolio of three patents that demonstrate his contributions to the fields of optical technology and magnetic materials. His work exemplifies how innovative thinking can lead to significant advancements in technology.

Latest Patents

One of Sonderman's latest patents is titled "Two-axial alignment of magnetic platelets". This invention discloses a method for planarizing a plurality of orientable non-spherical flakes supported by a longitudinal web. In this process, a web coated with field orientable non-spherical flakes is placed between magnets, which generate magnetic fields that interact with the flakes as they move along a feedpath. The configuration of the magnets promotes a rotational effect on the flakes, facilitating their alignment before the coating is cured.

Another significant patent by Sonderman is the "Variable filter-based optical spectrometer". This innovative optical spectrometer employs a tapered Fabry-Perot type variable optical filter alongside an optical detector array. The design allows for various filtering capabilities, be it long-pass, short-pass, or narrow bandpass filtering. The stability of the variable optical filter contributes to high resolution, enhanced further by advanced signal-processing techniques.
