<title>High-speed photography and photonics in Korea</title>

Abstract

Ladies and gentlemen, before I start my technical talk I want to welcome all of you to this congress in Taejon. It is a great pleasance to meet old friends and colleagues, in Korea. The high speed photography technology in Korea is now resonably matured in the last 15 years of time, the experimental technique has been innovated, and it has acquired elaboration and exploration as the speed of the phenomenon is getting faster and the applications are diversified. There are many applications of the m-sec high speed technique in the industries. In these cases although the speed is slow, usefulness of the image obtained is tremendous. p -sec high speed photography is applied in the usual ballistic and explosion researches and combustion researches of heat engines and jet engines. The applications of high speed laser pulse(n-sec, p-sec, and f-see) are made in chemical kinetics researches and laser plasma researches. We do not have many dedicated manufacturing industry for high speed photography instruments. The high speed cameras are in many cases imported from abroad, however, there is one efficient and active industry of medium size which is covering a major portion of the high speed framing and streak camera market in Korea.
