Since conventional optics does not always work in the range outside the visible light (UV, IR) , it is very interesting how 3D imaging can be applied in this range.
Can somebody give relevant references?
Thank you in advance.
Dear Vladimir, non-linear multiphoton microscopy, either fluorescence based or second-/third-harmonic generation microscopy is ideally suited for 3D imaging in single cells and tissues using infrared pulsed lasers. Please refer to work from our lab (Friedrich et al. 2010, Biophys J; Buttgereit et al. 2013 J Pathol; Schürmann et al. 2013, Gastroenterology; Vielreicher et al. 2013, J R Soc Interf) or from the labs of Schenke-Layland, Pavone, Ralston, for example.
Dear Vladim, I am working in this area and built one of the first stereoscopic multispectral cameras, with heart surgery as application area. See the attached article. A stereoscopic microscope camera with 5 bands per eye is still intensively used in Leiden UMC. Visionsense corporation just recently released a commercial stereoscopic multispectral surgical camera that also combines near infrared information with the normal visible image. Within TNO we furthermore perform research that allows true 3D reconstruction of endoscopic panoramas that are much wider then a single endoscope image (see other attached article). We also do 3D in radar, teraHerz, ground penetrating radar, etc.
Vlad,
Other NIR techniques you may want to look at are Diffuse Optical Tomography (DOT) and Photoacoustic Tomography (PT). In DOT, arrays of multiple light sources and detectors are used to reconstruct the image using various back-projection algorithms. In PT, a combination of ultrasound and light is employed. For PT, look at papers of Lihong Wang

Hi Vladimir. There is no information structure 'blur' in the phenomenon of vision. No motion blur, no depth of field. There are no pictures in vision. No picture frames and no frames per second. As there are no pictures to call up then there is no binocular fusion going on. We have developed a new form of illusionary space based on perceptual structure not the fundamentals of optics. This is termed Vision-Space instead of picture space. Its spatial saliency is not on the 1,2,3D curve. It's experiential spatial saliency or ExpD! Presentation list attached and articles are on my page.
Yes, e.g. at mm-waves
