| Research Abstract |
We developed a multi-focus excitation nonlinear Raman microscope using a microlens array scanner for real-time molecular imaging. Parallel exposure of a specimen with light from two highly controlled ps mode-locked lasers (jitter of 30fs, point-by-point wavelength scan within 300ms) and parallel detection with an image sensor enabled real-time imaging. We demonstrated real-time Raman imaging of living cells (frame rate of 10fps). We also combined the developed system with the laser ablation to destruct the cell membrane, and demonstrated to observe the membrane repairing process. We added the polarization pattern control system to a nonlinear Raman microscopy system to detect membrane proteins by control the direction of electro-magnetic filed on the focus spot. The possibility of the selective detection of ordered molecules was confirmed with the imaging of liquid crystal.
