Title: Richard S. Sidell: Innovator in Illumination Systems
Introduction
Richard S. Sidell is a notable inventor based in Needham, MA (US), recognized for his contributions to illumination systems. He holds a total of 4 patents, showcasing his innovative approach to enhancing optical character recognition (OCR) technologies.
Latest Patents
One of Richard's latest patents is an illumination system designed for OCR of indicia on a substrate. This system incorporates one or more light sources, opaque baffles, and mirrors to effectively illuminate indicia on substrates, such as semiconductor wafers. The design allows for viewing by a camera that can be aligned either parallel to or at an angle to the substrate. The light sources utilized include light-emitting diodes (LEDs) for soft marks and broad-spectrum incandescent lamps for hard marks. Additionally, the system features dark field and light field illuminators, which enhance the reading of light indicia on dark backgrounds and dark indicia on light backgrounds, respectively. A light control unit is also included, enabling manual or automated control of light source selection and intensity. The use of opposing mirrors along the optical paths of the light sources increases illumination efficiency, allowing for fewer light sources to be used.
