Název v původním jazyce

Focal plane speckle patterns for compressive microskopic imaging in laser spectroscopy

Popis výsledku v původním jazyce

Speckle patterns arise due to interference of many coherent wavefronts with random phases. The patterns can serve as a means of random encoding of scenes for compressive imaging in laser spectroscopy, as is has been demonstrated for the far-field speckles. However, the use of far-field speckle patterns limits resolution of the imaging. Here we present a study of speckle patterns in the proximity of the focal plane of a lens, which can provide an access to speckle patterns on the micrometer scale. We demonstrate the possibility to obtain a scaled-up reference pattern and we also investigate correlation between speckle patterns in different positions close to the focal plane. Finally, we demonstrate single-pixel hyperspectral imaging based on focal plane speckles and discuss their other possible applications.
