“…An additional important feature of the method is that, in addition to the amplitude image, it also yields a quantitative phase map of the sample, contrary, e.g., to the conventional ghost imaging techniques that are able to reveal only amplitude information [19,20,37]. (By adapting the principles of phase contrast or holographic microscopies, it is possible to retrieve phase information by ghost imaging, too, however, this extension demands a considerable increase of complexity of the experimental arrangement [38]- [41].) From the practical point of view, our measuring system is a scanning holographic microscope with a feature of wavelength conversion.…”

Novel imaging techniques utilizing nondegenerate, correlated photon pairs sparked intense interest during the last couple of years among scientists of the quantum optics community and beyond. It is a key property of such "ghost imaging" or "quantum interference" methods that they use those photons of the correlated pairs for imaging that never interacted with the sample, allowing detection in a spectral range different from that of the illumination of the object. Extensive applications of these techniques in spectroscopy and microscopy are envisioned, however, their limited spatial resolution to date has not yet supported real-life microscopic investigations of tiny biological objects. Here we report a modification of the method based on quantum interference by using a seeding laser and confocal scanning, that allows the improvement of the resolution of imaging with undetected photons by more than an order of magnitude, and we also present examples of application in the microscopy of biological samples.

“…A devised Young's interferometer is developed to reconstruct the 1D complex-valued object in the ghost diffraction [19]. Ghost diffraction imaging of pure phase objects, with intensity correlation, is also described [22][23][24][25]. A number of computational correlation techniques are proposed, such as computational ghost imaging [26,27], single-pixel imaging [28][29][30].…”

We propose a new scheme for the recovery of complex-valued objects in a single-pixel hybrid correlation holography. The idea is to generate an intensity correlation hologram from the correlation of intensity fluctuations obtained over two channels, namely an optical channel equipped with a single pixel detector and a digital channel. The scheme has a theoretical basis which is described to reconstruct the objects from a single pixel detector. An experimental arrangement is proposed and as a first step towards realizing/implementing the technique, simulation of the experimental model was carried to image three complex objects.

“…Conventional ghost imaging is used to capture the spatial proprieties of objects [1][2][3][4][5][6]. Recently, ghost imaging is extend to time domain for recording the temporal signal at picosecond level with a slow integrating detector without enough temporal resolution [7,8].…”

Ghost imaging obtains an image of an amplitude/phase object by spatial correlation between two separated light beams. In ghost imaging, two detectors are used in a counter-intuitive way. One is a multi-pixel detector that does not view the object in reference arm, and the other one is a single-pixel detector that does view the object but only record the total light power in object arm. Neither detector could recovery the object independently, but spatial correlation from two detectors allows the reconstruction of a ghost image of the object. Here for the first time we present ghost network analyzer for obtaining frequency properties of a target. Interestingly, this novel technique proves insensitive to the distortion introduced by nonlinear devices, while conventional frequency-domain measurement modalities such as network analyzer can hardly work properly with distortion. The proposed technique provides a breakthrough method for distortion-free dynamic frequency response analysis.
