Compressive sensing computational ghost imaging.
The computational ghost imaging with a phase spatial light modulator (SLM) for wave field coding is considered. A transmission-mask amplitude object is reconstructed from multiple intensity observations. Compressive techniques are used in order to gain a successful image reconstruction with a number of observations (measurement experiments), which is smaller than the image size. Maximum likelih...
متن کاملCompressive adaptive computational ghost imaging
Compressive sensing is considered a huge breakthrough in signal acquisition. It allows recording an image consisting of N(2) pixels using much fewer than N(2) measurements if it can be transformed to a basis where most pixels take on negligibly small values. Standard compressive sensing techniques suffer from the computational overhead needed to reconstruct an image with typical computation tim...
متن کاملComputational Ghost Imaging for Remote Sensing Applications
Although ghost imaging owes its early popularity to experiments geared towards demonstrating novel physical principles in quantum optics, it has since developed into a viable structured-illumination imaging modality. As the fundamental physical principles that govern ghost imaging are now well-understood in terms of the coherence theory for classical and quantum light, more attention is being d...

متن کاملLensless Compressive Sensing Imaging
—In this paper, we propose a lensless compressive sensing imaging architecture. The architecture consists of two components, an aperture assembly and a sensor. No lens is used. The aperture assembly consists of a two dimensional array of aperture elements. The transmittance of each aperture element is independently controllable. The sensor is a single detection element, such as a single photo-c...
