摘要：
The Narrow Field InfraRed Adaptive Optics System (NFIRAOS) in the Thirty Meter Telescope faces challenges with its Visible Natural guide star Wavefront (VNW) sensor's linear stages and encoders. Initial tests revealed deficiencies in magnetic encoders impacting pupil motion calculations at -30 degrees C. Retrofitting with inductive encoders by AMOSIN showed improvement, but fell short. A compensation algorithm was developed to reduce the error to acceptable levels. This paper presents insights from testing different encoders, exploring methods for qualification and troubleshooting, crucial for optimizing NFIRAOS performance in ground-based astronomy.
