OPTICAL CAVITY WITH INCREASED PHOTONIC EFFICIENCY AND AN OPTICAL GAS SENSOR, CAPABLE OF IMPROVING THE SENSITIVITY OF A SENSOR

摘要

PURPOSE: An optical cavity with increased photonic efficiency and an optical gas sensor are provided to improve the quantity of light per a unit area due to a light collecting effect by using the optical cavity with a concave wall structure.;CONSTITUTION: An optical gas sensor comprises a light source, an optical detector, and an optical cavity. The light source emits the light. The optical detector detects the light emitted from the light source. The optical cavity comprises a reflection wall side on which the light emitted from the light source. The optical cavity comprises an inlet mounting light source and an outlet in which the optical detector is installed.;COPYRIGHT KIPO 2010
