  • Method and device for incoherent imaging with coherent diffractive reconstruction
    Patent number: 10073025
    Abstract: Systems and methods are disclosed to determine the axial and/or lateral location of a particle using light modulated with temporal and/or spatial modulation pattern. The system, for example, may include a modulator configured to temporally modulate an intensity pattern of a line of light uniquely at each point along a lateral length of the line of light and produce an undiffracted modulated line of light, a first first-order diffracted line of light, and a second first-order diffracted line of light; and one or more optical elements configured to direct the undiffracted line of light and one of the first first-order diffracted line of light and the second first-order diffracted line of light toward at least one particle disposed at or near a sample region. The system may include a processor configured to determine an axial and/or a lateral position of the particle disposed at or near the sample region.
