Abstract
A flame detector includes a beam splitter to split mid-wave infrared radiation (MWIR) and long-wave infrared radiation (LWIR) into an MWIR component and an LWIR component. An MWIR detector detects the MWIR component and an LWIR detector detects the LWIR component. The flame detector analyzes the MWIR component to determine the presence of a flame and analyzes the LAIR component to determine whether the system is functioning properly.
