CCD camera-based diagnostics of optically dense pulsed plasma with account of self-absorption

摘要

Abstract. We present a system developed for the optically dense pulsed plasma diagnostics based on a digital video camera with a CCD matrix, that provides determination of spectral brightness and optical density with account of self-absorption. 1. Introduction Real sources of a pulsed plasma (lasers, discharges, etc.) are often not optically thin, so the diagnostics of such plasmas should be performed taking into account the reabsorption of the radiation in the investigated source [1].
