-Instrument Introduction

The polarization phenomenon of light is an important phenomenon in wave optics, and its discovery confirms that light is a transverse wave, meaning that the vibration of light is perpendicular to its propagation direction. The polarization properties of light have important applications in optical metrology, photoelastic technology, thin film technology, and other fields. This experiment uses a stepper motor to drive the rotation of polarizing devices such as polarizers and waveplates, and displays and measures the complex results of polarized light experiments through a computer interface. Study the characteristics of polarization and the role of waveplates, and observe polarization properties such as optical rotation and photoelastic effects.
