Liang-Yu Chen Multi-wavelength Diffuse Optical Imaging
Liang-Yu Chen,Min-Chun Pan,Min-Cheng Pan,

Diffuse optical imaging can show the map of chromophore concentration in the medium from multi-wavelength light measurement. In this study, initial simulation of diffuse optical imaging for reconstructing chromophore concentration, such as oxy-hemoglobin, deoxy-hemoglobin, and water, is presented.

Hung Van Nguyen Measurement of Refractive index of liquids using low-coherence fiber-optic Fabry-Perot interferometer
HungVan Nguyen,Shyh-Tsong Lin,

In this article, the mathematical analysis and experiment set up of low-coherence fiber optic Fabry-Perot interference have been demonstrated. Since we want to confirm the ability in determining refractive index of liquid, a series of test with water samples and without sample were conducted under favorable conditions.

Yu-Han Chang Non-invasive method to evaluate hepatic functions by two-photon fluorescence microscopy of intravenous indocyanine green (ICG)
Yu-Han Chang,Kai-Wen Huang,Yao-Ming Wu,Tzu-Ming Liu,

We developed an in vivo non-invasive detection system with two-photon fluorescence to conduct a preoperative assessment of hepatic functions. In our rat models, the residual ICG on 15 minutes post administration (ICG-R15) in rats with hepatocellular carcinoma is above 40%; control group, below 15%. It's as accurate as traditional methods.

Chia-Ta Tseng Simulation analysis of the angular span of the Optical Phase Conjugation Phenomenon using pseudospectral time-domain technique
Chia-Ta Tseng,Snow H. Tseng,

The pseudospectral time-domain (PSTD) technique is employed to obtain numerical solutions of Maxwell’s equations. Outgoing light is recorded and used to generate phase-conjugated light which back-propagates through the scattering medium. By changing the angular span, we can analyze different angular spans and help determine the optimal angular span for back-propagation of light.

Shi-Hao Huang OCT tomographic reconstruction of melanin structure via finite-difference time-domain simulation
Shi-Hao Huang,Shiang-Jiu Wang,snow H Tseng,

The finite-difference time-domain method (FDTD) can help us to analyze data acquired in the optical coherence tomography (OCT). We reconstruct the structure of melanin, which is the key component of human pigment system. Simulation reconstruction shows structures of the melanin that may be useful for biomedical optics application.

Chia-Wei Lee Nonlinear structured-illumination enhanced temporal focusing multiphoton excitation microscopy with a digital micromirror device
Li-Chung Cheng,Chia-Wei Lee,Chi-Hsiang Lien,Yong Da Sie,YulingYvonne Hu,Chun-Yu Lin,Fan-Ching Chien,Chris Xu,Chen Yuan Dong,Shean-Jen Chen,

The light diffraction of temporal focusing multiphoton excitation microscopy (TFMPEM) and the excitation patterning of nonlinear structured-illumination microscopy (NSIM) can be simultaneously implemented via a single high-resolution digital micromirror device. The lateral and axial spatial resolutions of the TFMPEM are remarkably improved through the second-order NSIM and structured light, respectively.
