En-Te Hwu has engineering background, he mainly focuses on instrumentation. He cooperates with PIs at Institute of Physics, Academia Sinica and builds custom made nano scale measurement/nano scale positioning systems for cutting edge experiments. En-Te Hwu builds an atomic resolution optical detection system which based on a DVD optical pick-up unig. This optical detection system called astigmatic detection system (ADS). The ADS has been widely used in homemade atomic force microscope (AFM), optical profiler, MEMS/NEMS vibrometers. Another important part for nano-scale instrumentations is nanopositioning system, En-Te Hwu built a new mechanism for driving pirzoelectric nanopositioner. There are many PIs adopt the homemade nanopositioning system for nano-scale X-ray microscops, micro-spotter system, multi-probe inspection system, long-time cell tracing systems. :
