A new method is proposed for measuring plasma density based on the direct determination of the phase shift of an electromagnetic wave during the passage of probe radiation through plasma using a broadband oscilloscope. The paper describes a scheme for measuring plasma density up to 4*10 13 cm −3 . Examples of using this method to determine the parameters of the inductively coupled plasma and plasma flows in a magnetic field are given.
