Density measurement of supersonic airflow using decay characteristics of FLEET emission

A method that involves the use of a femtosecond laser can be utilized for nonintrusive measurement of supersonic airflow without seeding any additional molecules. In the present study, the feasibility of using this method to measure the density in supersonic airflows is investigated. In the experime...
