Cheap Pix Three-dimensional (3D) images can be captured by, for example, holographic imaging or stereoimaging techniques. To avoid using expensive optical components that are limited to specialized bands of wavelengths, Sun et al. (p. 844 ; see the P

Pairs of planar ray-rotating windows can rotate the view through different angles. The angle by which an object appears rotated is independent of the distance of the object behind the windows. The observer distance has to be chosen such that the obse

Conventional cameras rely upon a pixelated sensor to provide spatial resolution. An alternative approach replaces the sensor with a pixelated transmission mask encoded with a series of binary patterns. Combining knowledge of the series of patterns an

Computational ghost imaging is a technique that enables lensless single-pixel detectors to produce images. By illuminating a scene with a series of patterns from a digital light projector (DLP) and measuring the reflected or transmitted intensity, it

Single-pixel detectors can be used as imaging devices by making use of structured illumination. These systems work by correlating a changing incident light field with signals measured on a photodiode to derive an image of an object. In this work we d

The field of ghost imaging encompasses systems which can retrieve the spatial information of an object through correlated measurements of a projected light field, having spatial resolution, and the associated reflected or transmitted light intensity

Computational ghost imaging retrieves the spatial information of a scene using a single pixel detector. By projecting a series of known random patterns and measuring the back reflected intensity for each one, it is possible to reconstruct a 2D image

Computational ghost imaging uses projection of random patterns and backscattered signals recorded by a photodiode to produce an image. Sequentially projecting a pattern and its inverse at a fixed frequency of 1440Hz allows demodulation of the measure

In this computational ghost imaging system we use a digital light projector to generate structured light patterns and a single-pixel detector to obtain a 2D image of a 3D object. Extending of this technique by using multiple single-pixel detectors in
