Introduction

Crystals will produce a birefringence effect under the action of electric fields, ultrasonic waves, and magnetic fields. This effect can be used to measure relevant physical quantities and to modulate the phase and intensity of light. The electro-optical,acousto-optical and magneto-optical effects of crystals are the three most common modulation phenomena. By integrating these three effects together, this experiment makes it easier for teachers to teach relevant knowledge and for students to compare experimental principles horizontally through experimental phenomena.
