Dynamic Holography Droplet Clouds Analysis System

To address the Army need for a high-speed measurement instrument to record and display water droplet demise through vehicle-induced shocks, Physical Optics Corporation (POC) proposes to develop a new Dynamic Holography Droplet Clouds Analysis System (DHDCAS) with the capability of measuring 3D volume domains, particle velocity and size distributions, shape, and mass as a function of time. The proposed DHDCAS is based on dynamic holography with an enhanced photorefractive semiconductor material. The innovation in DHDCAS will enable the system to record holograms at a very high speed, which will allow recording and visualization of dynamic events and provide 3D information of water droplet demise. In Phase I POC will demonstrate the feasibility of DHDCAS by designing, analyzing, and fabricating a breadboard setup. In Phase II POC plans to develop a prototype to test its capabilities of high-speed recording, displaying water droplet demise due to vehicle-induced shocks, and measuring particle velocity and size distributions, shape, and mass as a function of time in 3D volume domains.
