Ghost imaging or single-pixel camera utilises correlation measurement of two light beams to produce images. In the imaging process, light contacted with an object is only detected by a single-pixel detector with no spatial resolution, while spatial information is recorded by light that never “see” the object. Either of the two beams but their correlation can generate an image. This technique was first demonstrated using quantum entanglement and then mimicked by classical light. Classical ghost imaging was subsequently adjusted into a one-beam virtual correlation system (computational ghost imaging) by using a hologram controlled spatial light modulator. In computational ghost imaging, a series of known structured illumination is generated as light source, and the total light intensities after the object are detected by a single-pixel. An image of the object is retrieved from the correlation of these intensities and their corresponding illumination structures. In my presentation I will introduce the development of ghost imaging from 1995 and the computational ghost imaging system we developed in our lab, together with its applications in 3D reconstruction and realtime video record.
