An optical measurement process was produced to reach at optical Qualities of smoke deposited outside of a smoke layer onto glass filters. From this get the job done, the researchers utilized gravimetric measurements of these filters to demonstrate and validate an analytical model for smoke deposition according to thermophoresis. As a result, a fresh optical measurement strategy was designed to work with with electronic pictures and digital image analysis.
