An optical measurement process was made to reach at optical Houses of smoke deposited away from a smoke layer onto glass filters. From this perform, the researchers utilized gravimetric measurements of these filters to reveal and validate an analytical product for smoke deposition determined by thermophoresis. Therefore, a fresh optical measurement strategy was made to utilize with electronic photos and electronic image analysis.
