Outline of Final Research Achievements

In this study, we have investigated ultra-highly time-resolved imaging devices based on the lateral electric field charge modulator (LEFM) having a sub-picosecond time resolution and their applications. Toward the goal of 3D imaging for small space like in human body, a time-of-flight range imaging device having the resolution of 140um for single frame measurement and 40um with averaging 100frames has been realized. In fluorescence lifetime microscopy for weak fluorescence signals, an implemented imager having its intrinsic lifetime of 180ps and resolution of 14ps has been realized and a fluorescence lifetime image for a single cell has been successfully obtained. These results lead to the developments of the next-generation biomedical imaging tools using the small-size semiconductor sensor chips, which can be used for tumor detection in an endoscope.
