摘　　要：为了设计适用于可见光波段的云母λ/2消色差复合波片,根据三元复合波片理论,利用模拟退火算法,设计出了消色差λ/2复合波片。理论结果表明,在400~700 nm范围,复合波片的相位延迟偏差在2%以内。根据光相位延迟量的归一化偏振调制测量法,选用4个激光光源对该复合波片进行测试。实验结果表明,在可见光范围,以平均等效快轴为基准,器件的相位延迟偏差在4.8%以内;分别以测试波长对应的等效快轴为基准,其相位延迟偏差在2.9%以内。用模拟退火算法设计的云母λ/2消色差复合波片在可见光范围内实现了较好的消色差效果,具有一定的实用价值。According to three composite wave-plate theory and simulated annealing algorithm,a mica achromatic half wave-plate used in visible range is designed.Theoretical analysis shows that the retardation deviation of this device is within 2% covering the spectrum scope of 400~700 nm.This device has been measured over the visible range by normalized polarizing modulation measurement.The retardation deviation is within 4.8% based on the average equivalent fast axis.The retardation deviation of the device is within 2.9% based on the equivalent fast axis corresponds to the measuring wavelength.This mica achromatic half wave-plate can be applied in many fields.
