This document contains the specific requirements and preliminary results for the Optical Mass Capture (OMC) experiment for the Fundamental RESearch Hypersonic Flight experimentation (FRESH Fx) program. The objective of this effort is to develop and demonstrate in flight a diode-laser-based measurement of engine air mass capture in the inlet or isolator of a hypersonic vehicle over an altitude range of 60,000-90,000 ft with an average Mach number of 7.5 over this range. The concept involves the direct measurement of oxygen concentration via absorption spectroscopy, and gas velocity via the Doppler shift of laser light transiting the flowpath. The deduced density-velocity product in a known flow area yields the mass flow rate.
