Focal plane speckle patterns for compressive microskopic imaging in laser spectroscopy
Original language description
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.
