Tomographic imaging of macroscopic biomedical objects in high resolution and three dimensions using orthogonal-plane fluorescence optical sectioning

Jan A. N. Buytaert & Joris J. J. Dirckx
A new optical-fluorescence microscopy technique, called HR-OPFOS, is discussed and situated among similar OPFOS-implementations. OPFOS stands for orthogonal-plane fluorescence optical sectioning and thus is categorized as a laser light sheet based fluorescence microscopy method. HR-OPFOS is used to make tomographic recordings of macroscopic biomedical specimens in high resolution. It delivers cross sections through the object under study with semi-histological detail, which can be used to create three-dimensional computer models for finite-element modeling or anatomical studies....

Angular displacement and deformation analyses using a speckle-based wavefront sensor

Percival F. Almoro, Giancarlo Pedrini, Arun Anand, Wolfgang Osten & Steen G. Hanson
Wavefronts incident on a random phase plate are reconstructed via phase retrieval utilizing axially displaced speckle intensity measurements and the wave propagation equation. Retrieved phases and phase subtraction facilitate the investigations of wavefronts from test objects before and after undergoing a small rotation or deformation without sign ambiguity. Angular displacement (Δθ) between incident planar wavefronts is determined from the light source vacuum wavelength (λ) divided by the fringe spacing (Λ). Fourier analysis of the wavefront...

Photonic not and nor gates based on a single compact photonic crystal ring resonator

Jibo Bai, Junqin Wang, Junzhen Jiang, Xiyao Chen, Hui Li, Yishen Qiu & Zexuan Qiang
New all-optical not and nor logic gates based on a single ultracompact photonic crystal ring resonator (PCRR) have been proposed. The PCRR was formed by removing the line defect along the ΓM direction instead of the conventional ΓX direction in a square-pattern cylindrical silicon-rod photonic crystal structure. The behavior of the proposed logic gates is qualitatively analyzed with the theory of beam interference and then numerically investigated by use of the two-dimensional finite-difference time-domain method....

High-speed linear detection time domain optical coherence tomography with reflective grating-generated spatial reference delay

Yuuki Watanabe, Fumitoshi Sajima, Toshiki Itagaki, Kei Watanabe & Yuuki Shuto
We developed a high-speed linear detection time-domain optical coherence tomography (OCT) technique that detected a reflective grating-generated spatial optical delay in the reference arm using a line scan camera during probe-beam scanning. Using an InGaAs line scan camera (512 pixels) operating at 47,000 lines/s, the calculation of the absolute value of the difference between two sequential lines can be approximately displayed as cross-sectional images with 500 lateral pixels at 94 frames/s . After data acquisition,...
