Abstract: An optical detector device may receive a spectroscopic measurement from a multispectral sensor. The optical detector device may determine, based on the spectroscopic measurement, a particulate size of a particulate. The optical detector device may determine, based on the spectroscopic measurement, an identification of the particulate. The optical detector device may determine, based on the particulate size and the identification of the particulate, that an alert condition is satisfied. The optical detector device may trigger an alert based on determining that the alert condition is satisfied.

Abstract: In some implementations, an optical device may include an aperture, one or more optical elements, an optical filter, and an optical sensor. The aperture may be configured to receive light. The one or more optical elements may be configured to diffuse the light received by the aperture, direct the diffused light to the optical filter via a folded optical path, wherein a length of the folded optical path is greater than a distance between the aperture and an input surface of the optical filter, and cause the diffused light to be distributed across the input surface of the optical filter. The optical filter may be configured to filter the diffused light distributed across the input surface of the optical filter to pass portions of the diffused light associated with one or more wavelengths to the optical sensor.
