7. 내용요약 :
For the past two decades, two-photon or multiphoton excitation has been very popular in the field of three dimensional (3D)
biomedical imaging and microfabrication. In the view of imaging, it has intrinsic optical sectioning capability,
and it has less photobleaching and photodamage effects on the samples. In terms of fabrication,
it generates 3D structures with fabrication resolution beyond diffraction limit, by utilizing the highly nonlinear kinetic process of polymerization.
However, point-by-point scanning and writing slows imaging and production processes, and this limits the potential applications of
this technique even though the intrinsic 3D resolution is very attractive for creating 3D images in high-throughput microcopy and 3D structures in mass production.
In this talk, several high-speed imaging and fabrication techniques based on ultrafast optical pulse manipulations will be proposed:
handheld multifocal multiphoton excitation fluorescence microscopy, wide-field illumination multiphoton excitation fluorescence microscopy for
Image Correlation Spectroscopy (ICS), and 3D lithographic microfabrication system.
Basic principles of ultrafast optical pulse manipulation will be introduced, and the proposed techniques will also be evaluated empirically. Lastly,
the viability for their potential applications will be discussed.
