● Familiarize with principle of Michelson interferometer
● Observe interference phenomenon of Michelson interferometer
● Measure relationship between expansion and driving voltage of PZT
● Calculate related characteristics of PZT
● Include He-Ne laser with power supply
Based on a Michelson interferometer, LEOI-38 is designed to study the piezoelectric characteristics of a piezoelectric transducer (PZT) so that the intensity distribution of interference can be obtained. Through this system, students can further understand the principle of the Michelson interferometer, acknowledge the characteristics of the PZT, and familiarize with the measurement technique of micro displacement.
Using this system, the following experiment examples can be conducted:
1.Construct a Michelson interferometer
2.Characterize a PZT
3.Calculate the piezoelectric coefficient of a PZT
