Study On The Characteristics Of Reproducing Light Polarization In Line Polarizing Holographic

The polarizing holographic theory based on the amount of diastonic can describe the polarizing holographic characteristics at any interference angle.In this paper,the paper studies the reproduction characteristics of polarizing holograms based on line-polarized light recording and verifies them by experiment.The theoretical and experimental results show that when any line polarization light is used to record and read any line polarization light,the polarization state of the reproducing light is not only related to the polarization state of recording signal light,reference light and reading the viewing light,but also with the dielectric volume coefficient of the material and the interference angle of the two recordings.Selecting the appropriate two-record optical interference angle can obtain a relatively simple and regular rewire light polarization characteristics.When the two recorded light interference angle is 90 degrees and the intensity response grating and the polarization response grating are balanced(when the recorded reference light is P light,the conditions for balancing the intensity response grating and the polarization response gratgies are not required),as long as the reference light is read Without orthogonalization with the direction of recorded reference light polarization,the diffraction light can be reproduced faithfully to the polarization state of the recorded signal light,and the diffraction light diffraction efficiency is related to the angle in the direction of reading the reference light polarization and the angle in the direction of the recorded reference light polarization.When the dissonant direction of the reading visiting light is consistent with the recorded reference light,the reproduction signal light is the maximum,and when the reading reference light and the record reference light polarization direction are orthogonal to each other,zero reproduction occurs.When the two recorded light interference angle is 0 degrees,and the intensity response grating and polarization response grating are balanced,the polarization angle of the reproducible light is dependent on the recording signal light polarization angle,the reading reference light polarization angle and the recorded reference light polarization angle.The diffraction efficiency of reproducing diffraction light does not change with the change of the polarization direction of the read reference light.The results of this study show that polarizing holographic holography has the potential to make polarized optical elements,and it is possible to design and produce a new type of polarizing biaser for changing the direction of incident light propagation and a new polarizing device that can rotate the polarized light polarization direction.
