In this study, highly time-resolved imaging devices using the DOM(draining only modulator) pixels for the observation of extremely high-speed phenomena are investigated for next-generation biomedical imaging and time-resolved 3D imaging. FLIM(fluorescence lifetime imaging microscopy) for HeLa cells stained with 2.5ns and 10ns fluorescence materials has been successfully demonstrated using an implemented FLIM imager. A new technique using an impulse response of the DOM pixels is introduced for high-resolution TOF range imaging and the range resolution of 300μm (time resolution of 2ps) has been successfully demonstrated with an implemented chip.
