Title: The Innovations of Norman J. Tobey
Introduction
Norman J. Tobey is a notable inventor based in Bedford, MA (US). He has made significant contributions to the field of optical encoders, showcasing his expertise through his innovative designs and patents. His work has had a lasting impact on the technology used in various applications.
Latest Patents
One of Tobey's key patents is the Reference Point Talbot Encoder. This optical encoder features a scale and a sensor head. The scale includes an optical grating and an optical element, while the sensor head comprises a light source, a detector array, and an index detector, all arranged on a substrate. The scale is positioned opposite the sensor head and is designed for movement relative to it. The distance between the scale and the sensor head is carefully selected so that the detector array is situated near a Talbot imaging plane. The light source emits a diverging beam of light directed towards the scale. Light from this beam is diffracted by the grating towards the detector array, while light is also diffracted by the optical element towards the index detector. The detector array measures the position of the sensor head relative to the scale, and the index detector provides a reference measurement of this position. This invention highlights Tobey's innovative approach to enhancing optical encoding technology.
