Abstract

Three-intensified-sensor color high speed video camera system with a cubic three-way beam-split prism and three optical filter holders has been developed. One of three image sensors can be assigned for the measurement of velocity and the others for that of temperature. Simultaneous measurements of temperature and velocity of sprayed particles are tried with this camera for understanding of the formation mechanism of spray coatings. The possibility of measuring the velocity of individual particle in plasma spraying is discussed for behavior analysis of sprayed particles with three-intensified- sensor color high speed video camera system. Furthermore the possibility for simultaneous measurements of temperature and velocity of individual sprayed particles is examined.
