Title: Mario Siciliani De Cumis: Inventor in Trace-Gas Detection

Introduction

Mario Siciliani De Cumis is an inventor associated with Catanzaro, Italy. His patent work focuses on photoacoustic spectroscopy, an approach to detecting trace gases by measuring sound generated when gas absorbs modulated laser light.

Latest Patents

The available information lists 1 patent for Siciliani De Cumis: “Photoacoustic Spectroscopy Sensor for Trace Gas Detection and Method for Trace Gas Detection.” The invention describes a sensor chamber containing the gas under examination and an excitation laser that emits a modulated beam. A transducer inside the chamber has a reflective portion and forms one end of an interferometer’s first arm.

The interferometer’s second arm includes an optical-path-changing element and an actuator. Polarizing beam splitters, a second laser source, two detectors, and an electronic circuit support the measurement system. A feedback loop controls the actuator to adjust and stabilize the second arm’s optical path, keeping the difference signal at a desired constant value during gas-concentration measurements.
