| Outline of Final Research Achievements |
This research project aimed to develop a new method to enhance the spatial resolution in confocal laser scanning microscopy by exploiting vector beams, which have axially symmetric polarization distribution. In this method, the enhancement of the spatial resolution is achieved by the simple subtraction process for images separately acquired by different vector beams with various focal spot shapes. The focal spot shape is controlled by manipulating the spatial distributions of polarization and phase for vector beams. Based on this principle, the spatial resolution close to 100 nm was experimentally demonstrated in visible light imaging.
