| 摘要 |
The invention relates to a flame detector (10), comprising at least one objective (11), a CMOS chip (30), and at least one color filter (20), wherein the color filter (20) is an array of a plurality of filter elements (21, 22), wherein the plurality of filter elements (21, 22) comprises a first group of filter elements (21) that are permeable for a first wavelength range, wherein the plurality of filter elements (21, 22) comprises at least a second group of filter elements (22) that are permeable for a second wavelength range, and wherein the first wavelength range is a wavelength range (40) in which both a flame (F) and a source of interference (S) emit a significant amount of electromagnetic radiation and the second wavelength range is a wavelength range in which only the source of interference (S) or only the flame (F) emits a significant amount of electromagnetic radiation. |
