简要回顾了光弹偏振计在天文学中的应用，介绍了一种在松山天文台61厘米望远镜上连续使用6年的可见光和近紫外光弹性调制偏振计。该旋光计主要用于线性偏振测量，但也很容易适用于圆偏振测量。该仪器产生的数据灵敏度为 0.01%，具有长期绝对再现性。
The use of photoelastic polarimeters in astronomy is briefly reviewed, and a visible and near-UV photoelastic modulation polarimeter is described which has been in continuous service on the 61-cm telescope of Pine Mountain Observatory for 6 years. The polarimeter is used primarily for linear polarization measurements, but is easily adaptable to circular polarimetry. The instrument has produced data at a sensitivity level of 0.01%, with long-term absolute reproducibility.
