Latest Patents
Ralph A. Kelliher holds a patent for a device known as the Reference Point Talbot Encoder. This optical encoder comprises a scale and a sensor head. The scale features an optical grating and an optical element, while the sensor head includes a light source, a detector array, and an index detector, all mounted on a substrate. The design allows for the scale to move relative to the sensor head, with the distance between them optimized for performance. The light source emits a diverging beam of light directed towards the scale, where it is diffracted by both the grating and the optical element. The detector array measures the position of the sensor head relative to the scale, while the index detector provides a reference measurement. This invention showcases Kelliher's expertise in optical technology and its applications.
