Jabr Affiliation(s) Physics Department, College of Science and Technology, Al-Quds University, Jerusalem, Palestine . The School of Science Research, Al Qusais, Dubai . ABSTRACT For the first time, we report photoacoustic (PA) signal detection in a cell placed within the Michelson interferometer cavity in an attempt to relate photoacoustic effect to the Michelson fringe shift as a result of changes in the cell. Both detection schemes were investigated using IR absorption and their sensitivities compared. Signals related to Michelson interferometer fringe and PA effect have...
