Time-of-flight three-dimensional imaging is an important tool for applications such as object recognition and remote sensing. Conventional time-of-flight three-dimensional imaging systems frequently use a raster scanned laser to measure the range of each pixel in the scene sequentially. Here we show a modified time-of-flight three-dimensional imaging system, which can use compressed sensing tec...

R ecently there’s been a push among some of our clients to start bringing 3d imaging systems in-house. In the majority of cases the client wants my company to provide some form of training to help them get off on the right foot. Although we are in the consulting business, training is a different animal. We’ve worked for years, continuously refining our processes and tools, investing in R&D and ...

Lensless ghost imaging (LGI) with thermal light requires an equal length between the test and reference arms. When this condition is not met, the image becomes blurred. Here we propose an experimental scheme of LGI where the lengths of the two arms are not equal. Our experiment shows that when a glass rod is inserted into a longer arm, the clear image can be formed in the intensity correlation ...

A new technique for high fidelity three-dimensional imaging of atomic structure with gamma-ray holography is demonstrated. A complex hologram was constructed from holograms recorded for different values of the nuclear scattering amplitude on both sides of the (57)Fe Mössbauer resonance. The holographic reconstruction was applied to this complex hologram resulting in a twin-image-free image of t...
