Abstract: A method of generating an image of a sample is provided. The method comprises providing a plurality of photon detectors, scanning the sample with an excitation beam over a predetermined time period, the detectors receiving photons emitted by the sample due to the excitation during the time period. A plurality of intensity images associated with each of the detectors are generated, each being proportional to the mean number of photons detected per unit time. A plurality of correlation images associated with each combination of two of the detectors are generated, each of the correlation images being proportional to the variance of the distribution of detected photons per unit time. The image of the sample is generated using joint sparse recovery from the plurality of intensity and correlation images, wherein the intensity and correlation images have common support.

Abstract: The present invention is based on a unique design of a novel structure, which incorporates two quantum dots of a different bandgap separated by a tunneling barrier. Upconversion is expected to occur by the sequential absorption of two photons. In broad terms, the first photon excites an electron-hole pair via intraband absorption in the lower bandgap dot, leaving a confined hole and a relatively delocalized electron. The second absorbed photon can lead, either directly or indirectly, to further excitation of the hole, enabling it to then cross the barrier layer. This, in turn, is followed by radiative recombination with the delocalized electron.

Abstract: A method and system for use in reconstruction and retrieval of phase information associated with a two-dimensional diffractive response are presented. The method comprising: providing (75) input data indicative of one or more diffractive patterns corresponding to diffractive responses from one or more objects (50). Dividing (130) said input data into a plurality of one-dimensional slices and determining (140) one-dimensional phase data for at least some of said one-dimensional slices. Tailoring (150) the reconstructed phase data of said one-dimensional slices to form a two-dimensional phase solution. The two-dimensional phase solution is defined by phase shifts of said reconstructed one-dimensional phase data of said one-dimensional slices. The two-dimensional phase solution thus enables obtaining two-dimensional reconstructed phase data suitable for reconstruction of image data (250).
