    摘要: Various embodiments are directed to methods, apparatuses, and systems for sensing one or more gases and particulate matter. In various embodiments, a method of detecting a gas and particulate matter within a sensing region comprises emitting, from a beam component, an optical beam along a beam path defined within a sensing region; detecting particulate matter within the sensing region based on particulate data generated by one or more photodetector, the particulate data being defined by a detection of a scattered portion of the optical beam reflected from a particulate positioned along the beam path; and detecting a first gas based on gas data generated by the beam component, wherein the gas data is generated by the beam component via an optical gas sensing means, and wherein the gas data is defined by a detected absorption of the optical beam at a first wavelength corresponding to the first gas.

    摘要: Provided are a light source (2) that emits light to be applied to a sample, a spectroscopic element (12) that disperses the light from the sample for each wavelength; and a light receiver (14) in which light receiving elements for detecting light of each wavelength dispersed by the spectroscopic element (12) are arranged, the light receiver (14) having a surface in direct with a filter layer (16) that shields high-order diffracted light from the spectroscopic element.
