摘要:
The integral value of the refractive index of a plasma in a toroidal device is measured by a stabilized Michelson interferometer with a HeNe gas laser (&lgr; = 0.63 &mgr;) as light source. A calibrated phase modulator enhances the accuracy with which small phase shifts are measured, and automatically indicates phase shifts exceeding &pgr;/2.
