title: Development of double-filtering imaging acousto-optic tunable filter with increased spectral resolution.
abstract: The spectral resolution is a key index of evaluating the performance of the designed acousto-optic tunable filter (AOTF). We present a special double-filtering method of obviously enhancing the spectral resolution. We have discussed the main technique functional in the double-filtering method in detail. It is confirmed that the double-filtering method can effectively enhance the spectral resolution with good imaging quality. This study is significant in the imaging applications of AOTF.
