Systematic analysis of SNR in bipartite Ghost Imaging with classical and quantum light

, 2011
We present a complete and exhaustive theory of signal-to-noise-ratio in bipartite ghost imaging with classical (thermal) and quantum (twin beams) light.

Spheroidal nanoparticles as thermal near-field sensors

, 2011
We suggest to exploit the shape-dependence of the near-field heat transfer for nanoscale thermal imaging. By utilizing strongly prolate or oblate nanoparticles as sensors one can assess individual components of the correlation tensors characterizing the ...

Observation of Intensity-Intensity Correlation Speckle Patterns with Thermal Light

, 2014
In traditional Hanbury Brown and Twiss (HBT) schemes, the thermal intensity-intensity correlations are phase insensitive. Here we propose a modified HBT scheme with phase conjugation to demonstrate the phase-sensitive and nonfactorizable features for ...

Thermal Model Calibration for Minor Planets Observed with Wide-Field Infrared Survey Explorer/Neowise [PDF]

, 2011
With the Wide-field Infrared Survey Explorer (WISE), we have observed over 157,000 minor planets. Included in these are a number of near-Earth objects, main-belt asteroids, and irregular satellites which have well measured physical properties (via radar ...

Thermal intravascular photoacoustic imaging

Biomedical Optics Express, 2011
Intravascular photoacoustics (IVPA)-a minimally invasive imaging technique with contrast related to optical absorption properties of tissue, can be used to visualize atherosclerotic plaques. However, the amplitude of photoacoustic signals is also related to a temperature dependent, tissue specific parameter-the Grüneisen parameter.

Two-photon interference with true thermal light

, 2005
Two-photon interference and "ghost" imaging with entangled light have attracted much attention since the last century because of the novel features such as non-locality and sub-wavelength effect.
