Scattering of electromagnetic radiation is caused by the interaction of radiation with matter resulting in the reradiation of part of the energy to other directions not along the path of the incidint radiation. Scattering effectively removes energy from the incident beam.
UV reflectors and UV-based light sources having reduced UV radiation leakage incorporating the same
InactiveUS20020180351A1Uniform colorUniform light intensityIncadescent screens/filtersMirrorsRadiation leakagePhosphor
UV reflectors incorporated in UV LED-based light sources reduce the amount of UV radiation emission into the surroundings and increase the efficiency of such light sources. UV reflectors are made of nanometer-sized particles having a mean particle diameter less than about one-tenth of the wavelength of the UV light emitted by the UV LED, dispersed in a molding or casting material surrounding the LED. Other UV reflectors are series of layers of materials having alternating high and low refractive indices; each layer has a physical thickness of one quarter of the wavelength divided by the refractive index of the material. Nanometer-sized textures formed on a surface of the multilayered reflector further reduce the emission of UV radiation into the surroundings. UV LED-based light sources include such a multilayered reflector disposed on an encapsulating structure of a transparent material around a UV LED, particles of a UV-excitable phosphor dispersed in the transparent material. Alternatively, the transparent material also includes nanometer-sized particles of a UV-radiation scattering material.

Apparatus for differentiating blood cells using back-scatter
InactiveUS6869569B2Material thermal conductivityMaterial analysis by electric/magnetic meansPhotodetectorRed blood cell
Blood cells of interest are readily distinguishable from other blood cells and look-a-like particles found in a blood sample by their back-scatter signature. A preferred method for differentiating platelets in a blood sample is to irradiate the cells and particles, one at a time, with a beam of radiation, and to detect back-scattered (reflected) radiation using a plurality of optical fibers to transmit the back-scattered radiation to a high-gain photodetector, e.g. a photomultiplier tube. Preferably, the back-scatter signal so obtained is combined with a second signal representing, for example, either the level of forward-scatter within a prescribed, relatively narrow angular range, or the level of side-scattered radiation, or the level of attenuation of the cell-irradiating beam caused by the presence of the irradiated cell or particle in the beam, or the electrical impedance of the irradiated cell or particle, to differentiate the cells of interest. The method and apparatus of the invention are particularly useful in differentiating platelets and basophils in a blood sample.

Disclosed are methods, systems, and computer-product programs for increasing accuracy in cone-beam computed tomography (CBCT) by obscuring portions of the radiation source so that the radiation only passes through the specific areas of the patient related to the regions-of-interest to the doctor. The obscuring action causes less radiation scattering to occur in the patient's body, thereby reducing a major source of error in the image accuracy caused by scattered radiation. Scattered radiation received by detector pixels that are obscured by direct-line of sight radiation may be used to estimate the scattered radiation in the un-obscured portion, which can be used to further increase the accuracy of the image.

Frequency calibration of a bi-static type of radar system is performed by positioning radar transmitter and receiver in spaced relation to each other over a targeted seawater surface from which radar radiation along a forward radiation scattering path is reflected toward the receiver while radar energy is also radiated along a direct path to the receiver by-passing the seawater during sequential frequency measurement tests to determine a frequency diffraction factor. A radiation blocking barrier is positioned by a floating support at a reflection location at an angular position on the seawater surface for intersection by the forward scattering path to block reflection of radar energy radiation toward the receiver during one of the measurement tests.

Increased absorption-measurement accuracy through windowing of photon-transit times to account for scattering in continuous webs and powders
InactiveUS8527212B2Accurate and more calibrationAccurate measurementRadiation pyrometryInvestigating moving sheetsPhoton transmissionMean free path
Radiation scattering is one of the main contributors to the uncertainty of near infrared (NIR) measurements. Enhanced absorption-measurement accuracy for NIR sensors is achieved by using a combination of NIR spectroscopy and time-of-flight techniques to select photons that are the result of a given mean free path within a moving sample target. By measuring absorption as a function of path length or by windowing signals that are attributable to excessive scattering of NIR radiation within the sample, this technique affords the calculation of more accurate and more universal calibrations. The NIR sensor employs short or ultra-short laser pulses to create NIR that is directed to the moving sample and emerging radiation is detected over time. Windowing effectively truncates non-contributing measurements.
