摘　　要：针对中性密度滤光片(以下简称滤光片)型近红外多通道光衰减器,提出了一种校准系统设计方案,并通过搭建校准系统对其进行了验证。结果表明,与传统的校准方案相比,本方案不仅能够缩短多通道可调衰减器的校准时间,而且还能够提高仪器的校准精度。A design scheme of the calibration system for a neutral density filter type near-infrared multichannel variable optical attenuator is proposed.To verify the scheme,a calibration system is built.The results show that compared with the traditional calibration scheme,this scheme not only can shorten the calibration time for the multi-channel variable optical attenuator,but also can improve the calibration accuracy of the instrument.
