Outline of Final Research Achievements

An active illumination microscope provides simultaneous acquisition of multi-contrast images such as bright-field, dark-field, and differential phase-contrast using various illumination patterns. We experimentally demonstrate the multi-contrast images of cells. The multi-contrast images of structural modifications were obtained by changing illumination patterns with an LED array and a projector for microscopic contrast enhancement. We present a method to obtain bright-field, dark-field, and DPC images and to discriminate depth structures by controlling spatial coherence of light sources. We acquired bright field, dark field, and DPC of biological cells as well as spectroscopic images and fluorescence images.
