Tissue and cellular imaging

Demetri Psaltis, Ye Pu, Ye Pu, Chia-Lung Hsieh, Xin Yang

Systems and methods for imaging ear tissue include: directing illumination radiation to pass through an intact biological structure and be incident on ear tissue that does not include an exogenous fluorophore, at a plurality of locations, the illumination ...

Optical parametric generation in periodically poled KTiOP O4 via extended phase matching

Demetri Psaltis, Ye Pu, Ye Pu

We report an experimental demonstration of optical parametric generation in a periodically poled KTiOP O4 crystal based on the principle of mirrorless optical parametric oscillation. A femtosecond pump pulse spectrally centered at 792 nm from a Ti:sapphire ...

Optical proximity sensing system for atraumatic cochea implant surgery

Demetri Psaltis, Christophe Moser, Ye Pu, Ye Pu

The design of a proximity sensor to be integrated into cochlea implants is described. The sensor allows the anticipation of contact between the cochlear implant and intracochlear structures, including the cochlear canal wall and basilar membrane, providing ...

Three-dimensional harmonic holographic microcopy using nanoparticles as probes for cell imaging: erratum

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh, Ye Pu

An error was made in calculating the polarization dependent second harmonic response of barium titanate nanoparticles. We have corrected the error and repeated the comparison with the experimental results. (C) 2010 Optical Society of America ...

Imaging through turbid layers by scanning the phase conjugated second harmonic radiation from a nanoparticle

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh, Ye Pu, Grégoire Pierre Jean Laporte

We demonstrate imaging through a turbid layer by using digital phase conjugation of the second harmonic field radiated from a beacon nanoparticle. We show that the phase-conjugated focus can be displaced from its initial position by illuminating the same r ...

Harmonic holographic microscopy with circularly polarized excitation

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh, Ye Pu

We have developed a luminescent marker using the second harmonic generation (SHG) from noncentrosymmetric BaTiO3 nanocrystals. These nanoparticles are attractive due to their stable, non-saturating and coherent signal with a femtosecond-scale response time ...

Lithium niobate nanowires synthesis, optical properties, and manipulation

Demetri Psaltis, László Forró, Arnaud Magrez, Ye Pu, Rachel Grange, Chia-Lung Hsieh, Ye Pu, Jae-Woo Choi, Rita Smajda

Free-standing lithium niobate nanowires (LiNbO3) are synthesized by the hydrothermal route. The polarization response of the second harmonic generation (SHG) signal is measured in a single nanowire and used to identify the crystal orientation by matching w ...

Harmonic Holographic Microscopy Using Nanoparticles as Probes for Three-Dimensional Cell Imaging

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh, Ye Pu

We demonstrate the three-dimensional imaging capability of harmonic holographic microscopy by using the second harmonic generation from BaTiO3 nanoparticles as the signal. Three-dimensional distributions of the BaTiO3 nanoparticles in biological cells are ...

Seeing through turbidity with harmonic holography [Invited]

Demetri Psaltis, Ye Pu, Ye Pu

The ability to see inside the body noninvasively is indispensable in modern biology and medicine. Optical approaches to such abilities are of rapidly growing interest because of their nonionizing nature and low cost. However, the problem of opacity due to ...
