Abstract: A low-cost, sensitive, laser-based (Helium Neon; He-Ne) optical Fourier-transformed (multiplexed) spectrometer has been constructed for the quantification of suspended particulates in the air. The optomechanical features of the spectrometer are presented together with a theoretical framework of its operation. The apparatus is calibrated by using a standard commercial spectrophotometer and has been successfully used to detect smoke of various densities. The simplicity in the design of the apparatus and sensitivity in its measurement would expectedly attract high school and college students and definitely help to spread the awareness of environmental pollution among younger generation.
