Quantitative phase measurements using optical quadrature microscopy.
Imaging of phase or optical path length is becoming more important with the development of better imaging systems, computational algorithms, faster computers, and a greater interest in the imaging of transparent objects. Early phase imaging involved qualitative imaging of phase gradients. New computational algorithms can be used to extract some quantitative phase imaging from these techniques. ...
متن کاملHarmonically-related diffraction gratings-based interferometer for quadrature phase measurements.
We demonstrate the use of shallow diffraction gratings for quadrature phase interferometry. A single shallow diffraction grating-based Michelson interferometer yields only trivial (0(o) or 180(o) ) phase shift between different output ports. In comparison, a combination of two parallel shallow diffraction gratings can be useful to achieve desired phase shifts (e.g., 90 (o) for quadrature phase ...
متن کاملQuadrature sampling phase detection
The demodulation of phase encoded high frequency carrier signals is a problem encountered in many applications and areas of research. Numerous electronic methods for demodulation of the carrier, including digital counting techniques and quadrature mixing demodulation have become standard.l Alternatively, the waveforms can be digitized and the phase extracted computationally.Q As the carrier fre...
متن کاملQuantum cryptography using continuous variable Einstein-Podolsky-Rosen correlations and quadrature phase amplitude measurements
Correlations of the type discussed by EPR in their original 1935 paradox for continuous variables exist for the quadrature phase amplitudes of two spatially separated fields. These correlations were experimentally reported in 1992. We propose to use such EPR beams in quantum cryptography, to transmit predetermined messages in such a way that the receiver and sender may later determine whether e...
