Introduction

James L. Fergason is a notable inventor based in Atheyton, CA (US). He is recognized for his significant contributions to the field of liquid crystal technology. His work has led to advancements that enhance the quality of stereoscopic imaging.

Latest Patents

Fergason holds a patent for a "Method and system employing a push-pull liquid crystal modulator." This innovative system and method utilize a push-pull modulator for stereoscopic image selection. The modulator consists of a pair of surface mode liquid crystal cells with orthogonal rub axes, along with a linear polarizer that has an absorption axis bisecting the orthogonal rub axes. This design provides high speed, good transmission, and symmetrical dynamic range characteristics. The technology allows for the transmission of a field-sequential stereoscopic video image from a video display screen or projector through the modulator. As the cells are driven, fields of alternately left-handed and right-handed circularly polarized light emerge. This transmitted circularly polarized light can be viewed using passive spectacles that incorporate circular polarizing filters.
