Embodiment Construction

[0203] based on figure 1 and figure 2 The measurable parameters of the particles shown. The apparatus for sorting particles comprises a feed conduit 10 which conveys particles sorted from a raw material supply 10A to a rotary body 11 rotatable about an axis 12, wherein the raw material Supply 10A continuously supplies particles for presentation through the conduit. In the embodiment shown, the rotating body is a flat disk, the axis 12 being arranged vertically such that the disk provides an upper horizontal surface onto which the particles 13 in the flow from the conduit 10 are fed. The conduit is placed at the center of the disc so that the particles are deposited on the center where the disc rotates but has little outward velocity. In exemplary cases, the particles may be grains. The grain velocity at this time comes from the flow in the feed conduit 10 . The velocity of a point on the disk is v=wr, where w is the angular velocity and r is the radius. If the grain is ...

Abstract

In a method for measuring radiation, the radiation is temporally and / or spatially separated by a modulator to direct at least N different combinations of radiation incident on each region into at least two and fewer than N distinct directions. The total intensity of radiation in each direction is measured with a detector for each modulator configuration and the detector outputs are analyzed statistically to obtain information relating to the spectral properties of the radiation. In this way substantially all of the energy received at the entrance aperture of a measurement device is encoded into multiple outputs and the multiplexed output is received by a small number of detectors.

Description

[0001] The present invention relates to measuring wavefields or particle fluxes using spatial and / or temporal modulation. A wavefield may include spatial variation of at least one feature or dependent variable. The invention is applicable to electromagnetic waves, matter waves and pressure (acoustic) waves. These electromagnetic waves, matter waves and pressure (acoustic) waves can be either transverse or longitudinal. The spatial variation or dependent variable of an electromagnetic wave can be amplitude, intensity, frequency, wavelength, phase, polarization direction of propagation, or origin location. [0002] Electromagnetic waves may also be referred to as photon fluxes. Matter waves may also be referred to as particle fluxes of electrons, neutrons, atoms, ions, molecules, or collections thereof. Spatial variations in particle flux can be related to any property of matter, including position of origin, velocity, acceleration, charge, mass, spin, quantum state, magnetic o...
