Complex Wavelets for Extended Depth-of-Field: A New Method for the Fusion of Multichannel Microscopy Images

Michaël Unser, Dimitri Nestor Alice Van De Ville, Daniel Sage

Microscopy imaging often suffers from limited depth-of-field. However, the specimen can be “optically sectioned” by moving the object along the optical axis. Then different areas appear in focus in different images. Extended depth-of-field is a fusion algo ...

Optical logic gates by nonlinear mixing in BBO

Demetri Psaltis

An experimental demonstration of a set of optical logic gates (OR, XOR, AND) is shown using non-linear mixing in a BBO crystal. Pulses generated by a femtosecond Ti:Sapphire laser at 800 nm (140 fs duration, 2nJ/pulse) are split in 4 beams evenly separated ...

The phases of CS3Bi2I9 between RT and 190 K

Gervais Chapuis, Alla Arakcheeva

The structure of Cs3Bi2I9 has been refined to R = 0.0165 on the basis of X-ray diffraction measurements at T = 290 K (STOE IPDS diffractometer; MoKalpha-radiation; 296 nonequivalent reflection with I > 2 sigma(I)). The absorption correction was accounted f ...

Optical fibers with patterned ZnO/electrode coatings for flexural actuators

Nava Setter

A fiber-based flexural actuator was developed using a patterned piezoelectric ZnO/electrode fiber coating on a standard telecommunications optical fiber. The actuator was composed of a concentric inner Cr/Au electrode, a thick sputtered ZnO coating, and an ...

Optical tomography at the microscopic scale by means of a numerical low coherence holographic technique

Christian Depeursinge, Etienne Cuche

We describe here a numerical application of the optical low- coherence holographic microscopy (OLCHM) technique. A low coherent source illuminates an object and the backscattered light interfere with a reference wave which optical path's length can be prec ...

Multi-material micro-electromechanical fibers with bendable functional domains

Fabien Sorin, Wei Yan, Alexis Gérald Page, Yunpeng Qu, Dang Tùng Nguyen, Marco Volpi

The integration of increasingly complex functionalities within thermally drawn multi-material fibers is heralding a novel path towards advanced soft electronics and smart fabrics. Fibers capable of electronic, optoelectronic, piezoelectric or energy harv ...
