Introduction

Ronald Paul Stahl is a notable inventor based in Castle Rock, CO (US). He has made significant contributions to the field of optical technology, holding 2 patents that showcase his innovative approach to solving complex problems in optical systems.

Latest Patents

Stahl's latest patents include a method for minimizing spherical aberration in optical read/write drives. This method, titled "Spherical aberration compensation by wavelength," provides an economic solution by pairing objective lenses with laser diodes. The goal is to offset the spherical aberration caused by the objective lens with that caused by the laser wavelength, thereby minimizing or completely canceling the overall spherical aberration.

Another significant patent is the "System for enhanced astigmatic focus signal detection." This auto-focus system is designed for DVD readers or other optical access units that read and write information from multiple layers on optical storage media. The system incorporates an astigmatic lens and a confocal aperture, which blocks extraneous out-of-focus light rays. This design allows for the creation of a focus error signal (FES) that drives a servo assembly to bring the access head into focus.
