| Outline of Final Research Achievements |
We have developed a new narrowband tunable filter to perform imaging spectroscopy of the solar chromosphere. It is possible to make high speed tuning (about 0.1sec), to exclude mechanical drives (and oil tank), and to cover a wide wavelength range (510--1100nm).
Using the filter, a series of high-resolution images were obtained with the 1m vacuum solar telescope at the Fuxian Solar Observatory on January 2015. We succeeded in observing several flares and fine structures of the chromospheric layer.On the other hand, we have developed an imaging polarimater combined with the universal tunable filter. The polarimater name is the Chromospheric Magnetograph with a Rotate wave-plate (called Chro-Mag-Ro). We observed circular polarization distribution around an active region on January 2016.
