Including the zero dimension there are five dimensions: 0 – 4. The eight points shown on the dimension circle (0 – 7) correspond to the eight directions on the Vector Equilibrium of space time. The circle of dimensions summarizes the laws of number and mathematics. Their reciprocal relation is clarified through the circle of 5 dimensions, based on the relation of infinity to one. See Greg's liquid crystal tunable filter spectrometer.Number is composed of the nine numerals, basic to all information, uniting geometry and arithmetic, space and time. Image was prepared by Gregory Bearman, JPL. The idea is to identify areas of the brain that perform specific functions without doing histopathaology on every slice. JPL and UCLA are utilizing hyperspectral techniques to generate functional mapping of the brain. Image is located at Nahum Gat and Suresh Subramanian, Opto-Knowledge Systems, Inc. X and Y are the 2D spatial map and Z is the wavelength dimension.

(OKSI) link Hyperspectral imaging.Įach pixel of a 2-D image has a full spectrum of information, shown here as the z-axis labeled 'lambda'. Nahum Gat and Suresh Subramanian, Opto-Knowledge Systems, Inc. 'lambda' means signal at a particular wavelength. Hyperspectral imaging is a 2-D image where each pixel has a full spectrum of information.

(OKSI): Nahum Gat and Suresh Subramanian, This month's gallery shows some of the current work from Greg Bearman at JPL and collaborators at UCLA on hyperspectral imaging of brain tissue slices.įurther information on hyperspectral imaging can be found at these sites: Now this technology is being applied to medicine. NASA and its various subcontractors have developed hyperspectral imaging based on reflectance spectra for satellite mapping of the planetary surface for weather, agriculture, and other tasks. Today video cameras are used rather than optical fibers to achieve high spatial resolution. of Texas-Austin, has been implementing fluorescence based hyperstatial imaging of the cervix to detect cervical dysplasia. The catheter had 19 fibers and hence the spatial resolution was coarse, however, the device could map the borders of artherosclertic plaque within arteries. Each fiber in a multiple-fiber catheter sequentially delivered excitation light and collected fluorescent emission to yield a fluorescence spectrum for that pixel.

One of the early examples in medical optics of hyperspectral imaging was the multifiber fluorescence probe developed by Michael Feld's group at M.I.T. Such an image is sometimes called a data cube or hypercube, in which the x-y plane shows the tissue structure and the z-axis encodes the wavelength-dependent information. Hyperspectral imaging is the technique of acquiring two-dimensional images in which each pixel has spectral information. to encourage the many other labs doing research in this field to post some images illustrating their work so that the general surfing audience can view our collective progress.to point interested viewers toward sites that report their development of optical technologies for medicine.to provide images that portray our field of biomedical optics and medical lasers.This month we emphasize hyperspectral imaging.
