Diffraction effects in optical interferometric displacement detection in nanoelectromechanical systems
... The displacement sensitivity (noise floor) per unit bandwidth attainable in our experimental setup at a given beam w by this technique depends upon RC共w , z兲 and the dominant noise source.14 The latter was set by the current fluctuations in our broadband amplifier with (white) spectral density, 冑SI ...

In this manner, we stained two haloalkane dehalogenase mutants, DbjA-H280F and DhaA-H272F. The measurements of time-resolv ...

Holography
... No interference occurs if the directions of polarization are perpendicular to each other; the visibility is 0. For optimal visibility object and reference wave have to polarized parallel each other. Even by using linearly polarized light radiation this cannot always be achieved in practice since lig ...
