Title: Charles D Hoke: A Pioneer in Mid-Infrared Imaging Technology
Introduction
Charles D Hoke, based in Palo Alto, California, is a prolific inventor with an impressive portfolio of 31 patents. His contributions to the fields of imaging and spectrometry have paved the way for significant advancements in various technological applications.
Latest Patents
Among his most recent innovations are two notable patents:
1. **Mid-infrared scanning system** - This patent describes an apparatus and method designed to generate mid-infrared region images of specimens. The system includes a mid-infrared laser to produce a first light beam, which is then focused on the specimen using an optical assembly. A detector measures the light intensity from the specimen, while a stage actuator enables multidimensional movement of the specimen for comprehensive scanning. The resultant mid-infrared image can be formed based on either reflected or transmitted light, showcasing a versatile approach to imaging.
2. **Calibration system for attenuated total reflection spectrometry** - This patent presents an ATR (Attenuated Total Reflection) scanner and the corresponding method for its calibration. It involves a focusing objective and a light beam that is directed to a specific point on a reflecting face without exceeding critical angles. A detector monitors light intensity reflected off the face while a controller manages the focal point location, thus allowing for precise measurements of incident and reflected light.
