“…It seems, however, that more recently the traditional form of intensity interferometry with classical light has received renewed attention in connection with stochastic electromagnetic fields [8][9][10][11][12] and, especially, in connection with classical counterparts of quantum imaging [13], namely, ghost imaging with classical light [14][15][16][17][18], ghost diffraction with classical light [19][20][21][22][23], and quantum-mimetic optical coherence tomography (OCT) [24][25][26].…”

“…Ghost imaging has been claimed as an alternative to carry out image transmission through an aberrating medium. 17 In the same context, the possibility for image transmission through highly scattering medium is of a high practical interest. 18, 19…”

Despite imaging systems that scan a single-element benefit from mature technology, they suffer from acquisition times linearly proportional to the spatial resolution. A promising option is to use a single-pixel system that benefits from data collection strategies based on compressive sampling. Single-pixel systems also offer the possibility to use dedicated sensors such as a fiber spectrometer for multispectral imaging or a distribution of photodiodes for 3D imaging. The image is obtained by lighting the scene with microstructured masks implemented onto a programmable spatial light modulator. The masks are used as generalized measurement modes where the object information is expressed and the image is recovered through algebraic optimization. The fundamental reason why the bucket detection strategy can outperform conventional optical array detection is the use of a single channel detector that simultaneously integrates all the photons transmitted through the patterned scene. Spatial frequencies that are not transmitted through this low-quality optics are demonstrated to be present in the retrieved image. Our work makes two specific contributions within the field of single-pixel imaging through patterned illumination. First, we demonstrate that single-pixel imaging improves the resolution of conventional imaging systems overcoming the Rayleigh criterion. An analysis of resolution using a low NA microscope objective for imaging at a CCD camera shows that single-pixel cameras are not limited at all by the optical quality of the collection optics. Second, we experimentally demonstrate the capability of our technique to properly recover an image even when an optical diffuser is located in between the sample and the bucket detector.

In computational imaging by pattern projection a sequence of microstructured light patterns codified onto a programmable spatial light modulator is used to sample an object. The patterns are used as generalized measurement modes where the object information is expressed. Our paper makes two specific contributions within the field of single-pixel imaging through patterned illumination. First, we perform an analysis of the optical resolution of the computational image. This resolution is shown not to be limited at all by the optical quality of the collection optics. This result is proved by using a low NA microscope objective for imaging at a CCD camera. Spatial frequencies that are not transmitted through this low quality optics are demonstrated to be present in the retrieved image through patterned illumination. Second, we experimentally demonstrate the capability of our technique to properly recover an image even when an optical diffuser is located in between the sample and the single-pixel detector.
