用高亮度LED和简便数据处理方法测定椭圆偏振光的椭圆曲线

Measurement of the elliptic curve of elliptically polarized lightusing LED and a simple method for data processing

通过建立椭圆偏振光在β方向上的光振动大小与检偏器在β+90°方向时光电检测器所测光强之间的关系式,以高亮度LED为光源,可简便地测定椭圆偏振光的椭圆曲线.

By deriving the expression for the relation between magnitude of light vibration of elliptically polarized light in the direction of β and light intensity measured by photoelectric detector when the analyzer is in the direction of β+90°,using LED with high brightness as light source,the measurement of the elliptic curve of elliptically polarized light can be realized simply.
