| Abstract: | An additional alternating electric field was applied in preparation of dichroic sheet so as to enhance Weigert effect. The relations between dichroic angle and electric field frequency and the relations between dichroic angle and electric field strength are obtained experimentally. Morever, it is found that additional electric field could remove the thermal negative effect. As the additional electric field of strength 3?200?V/m and frequency 13 65?MHz is applied, the dichroic angle can be enhanced by about 7 times. The reason of photo inducing dichroism and the additional electric field enhancing Weigert effect are discussed based on quantum perturbation theory and free electron oscillator model. |
