Polarization, Please --- The Missing Tool of the Trade

Author(s): WP Chen (NCU)

Presenter: Wen-Ping Chen (National Central University)

Photons provide information of a celestial body or a cosmic phenomenon more than available via photometry or spectroscopy. Polarization adds to the diagnosis tool. I will describe how a simple, compact imaging polarimeter affording 3 bands simultaneous measurements adapting to the Lulin One-meter Telescope makes the difference in scientific productivity and diversity. I then will highlight the polarization science at various wavelength ranges, advocating such instrumentation to be developed even for moderate-sized telescopes.
