Outline of Final Research Achievements

I built three instruments, A, B, C, for these three years in order to accomplish the scientific objectives.
A. TRIPOL(Triple Range Imager and POLarimeter). I built five sets of TRIPOL since 2010 and installed one of them(#2) on the Lulin 1m telescope. In collaboration with National Central University, Taiwan, I carried out the technical observations and confirmed 1) the limiting magnitudes and evaluated 2) the instrumental polarization. It works well enough for the scientific works. B. TRIPOL-SIRIUS. Combination of TRIPOL with SIRPOL/SIRIUS, a simultaneous 6-color polarimeter, is under construction yet. It will be shipped to SAAO by the end of 2015 and be commissioned at the Cassegrain platform of IRSF. C. i-POL. The instrument, i-POL, a wide field-of-view polarmeter, dedicated to the i-band polarization, was completed and be under evaluation on the Nagoya Science Musium telescope in collaboration with Nagoya Municipal University.
