Optical simulations as design tool for photoelectric smoke detector development

Room 105 (Level 1 South Lobby)

Abstract

The latest changes to the UL-217 & UL-268 standards challenge existing smoke detectors and necessitate the development of better performing devices. For photoelectric smoke detectors, optical simulation is a key instrument for the design and development phase. Based on an existing smoke detector we have built a complete optical model ranging from the component level up to the fully assembled module that was tested against experimental data. Based on this model, we investigated and optimized important optical design parameters such as interaction volumes and surface features to achieve better signal-to-noise levels while considering manufacturability and robustness against assembly tolerances.

Sven Stöttinger works as an optics design engineer at Excelitas Technologies. His main focus lies on optical simulations for various infrared emitting or sensing optoelectronic devices such as pyroelectric sensors for motion detection, thermopile sensors for contactless temperature sensing, and IR LED or laser sources and semiconductor detectors for range finding applications and photoelectric smoke detection. He joined Excelitas after finishing his PhD in Physical Chemistry from the Johannes Gutenberg University Mainz in 2017. His research background and experience is in the field of single molecule fluorescence microscopy and spectroscopy.
