Regarding the issue of insufficient study on both theoretical and experimental teaching of lightbirefringenee phenomenon in our university ,the phenomena of linear polarized light ,elliptically polarized lightand cireular polarized light passing through the iceland crystal were studied to effectively integratebirefringenee experiments with polarization experiments of light, based on the experiment of polarization ollight,The study on light birelringence experiment not only helps to lear difficult knowledge, but also helps toexpand knowledge and cultivate ,improve the abilities of observation ,thinking and operation.
