Fluorescence microscope by using computational ghost imaging

摘要

We propose a fluorescence microscope by using the computational Ghost imaging (CGI) for observing a living cell for a long duration over an hour. There is a problem for observing a cell about light-induced bleaching fora ling-term observation.Toover come the problem, we focused on an advantageof sensitivityof the CGI as second order colleration for an imaging with weak intensity excitation light. Setting for the CGI, a DMD projector was installed at an eye-piece part of a microscope and fluorescent light was detected using a bucket detectorofa photo-multiplier tube.Asaresults,wehaveshownthe imagingadvantageoftheCGI under weak light intensity, in addition, we have demonstrated to detect fluorescence images of biological samples for one day.
