Title: Innovations of Ronald A Palfenier
Introduction
Ronald A Palfenier is a notable inventor based in Oregon City, OR (US). He has made significant contributions to the field of radiometric temperature measurement systems, holding a total of 4 patents. His work has advanced the technology used in semiconductor wafer processing, showcasing his expertise and innovative spirit.
Latest Patents
One of his latest patents is a radiometric temperature measurement system. This system is designed to reduce optical losses and improve wavelength selectivity, signal-to-noise ratio, and signal processing. It enables accurate wafer temperature measurements ranging from about 10°C to 4,000°C. The system utilizes a YAG rod collection optic that directly couples specimen radiation to a filter and photo detector. The filter plays a crucial role in determining which radiation wavelengths are measured, and it may include a hot/cold mirror surface to reflect undesired wavelengths back to the specimen. The detector is formed from doped GaAlAs, which has a peaked response near 900 nm. A signal processor converts the detected signal into a temperature reading.
Another significant patent by Palfenier is a method of optical pyrometry that operates independently of emissivity and radiation transmission losses. This radiometric detector also features reduced optical losses and improved signal processing methods. It achieves temperature measurements of an object from about 10°C to 4,000°C. Similar to his previous invention, it employs a YAG rod collection optic that couples object radiation to a filter and photo detector. The preferred measurement method involves using at least two detectors, each detecting a different wavelength range. This dual-wavelength temperature measurement computation is particularly advantageous as it is independent of radiation transmission losses and the emissivity of the object being measured.
