Title: Rene Lange - Innovator in Infrared Detection Technology

Introduction

Rene Lange is a notable inventor based in Hombrechtikon, Switzerland. He has made significant contributions to the field of infrared detection technology, holding 2 patents that showcase his innovative approach to enhancing security systems.

Latest Patents

One of his latest patents is an "Infrared intrusion detector with a multi-layer mirror." This invention utilizes a focusing mirror that reflects incident infrared radiation onto a pyroelectric sensor element. To prevent extraneous radiation from interfering with the sensor, the mirror features a reflective layer for the desired infrared radiation and an absorptive layer to absorb unwanted radiation. This technology is particularly effective in detecting human body thermal radiation while filtering out visible spectrum interference. Doped indium-tin oxide (ITO) is preferred for the reflective layer.

Another significant patent is the "IR intrusion detector using scattering to prevent false alarms." This device employs infrared-sensitive sensors with pyroelectric elements to detect infrared radiation from monitored areas. The design includes an entrance window that allows infrared radiation to reach the sensor elements via focusing mirrors. Extraneous radiation is minimized through filtering at the entrance window and optical transmission filters, as well as scattering at the rough surfaces of the focusing mirrors. This innovation reduces the likelihood of false alarms, enhancing the reliability of security systems.
