Abstract:
An apparatus to identify at least one component from a plurality of components in a fluid mixture, the apparatus comprising a first input channel into which a first flow is introduced, said first flow which contains the fluid mixture of the plurality of components; a plurality of buffer input channels, into which additional flows of buffer solution are introduced, said plurality of buffer channels which are disposed on either side of said first input channel; wherein said first flow and said additional flows have a flow direction along a length of the apparatus from one end of the apparatus to another end of the apparatus; at least one output channel disposed at said another end of the apparatus, said at least one output channel which is adapted to receive selected components of the plurality of components, said selected components which are selectively identified from said first flow; and a laser apparatus which emits a laser beam which damages or kills said selected components of the plurality of components.
Abstract:
A method and an apparatus for achieving transformation of a virtual view into a 3D view are provided. The method comprises the following steps of: S1. capturing position coordinates of a human eye by a human-eye tracking module; S2. determining a rotation angle of a virtual scene according to the position coordinates of the human eye and coordinates of a center of a screen of a projection displaying module and rotating the virtual scene according to the rotation angle to obtain a virtual holographic 3D view matrix by a first image processing module; S3. determining a shearing angle for each of viewpoints according to coordinates of a center of the virtual scene, position coordinates of a viewer in the scene and coordinates of the viewpoints to generate a shearing matrix for the viewpoint in one-to-one correspondence, and post-multiplying the shearing matrix with a corresponding viewpoint model matrix to generate a left view and a right view by a second image processing module; and S4. projecting the left view and the right view of each of the viewpoints by the projection displaying module. In this way, the method and the apparatus for achieving transformation of a virtual view into a 3D view according to the present disclosure can achieve the purpose of holographic 3D displaying.
Abstract:
A method and system for beam shaping employing a non-collinear quasi phase-matched interaction in a crystal whose nonlinear coefficient was encoded by a computer generated hologram is provided herein. The same axis is used for both satisfying the phase-matching requirements and encoding the holographic information. This allows one-dimensional beam shaping using a very simple to fabricate nonlinear crystal pattern and two-dimensional beam shaping with high conversion efficiency. Both are demonstrated by converting a fundamental Gaussian beam into Hermite-Gaussian and Laguerre-Gaussian beams at the second harmonic in KTiOPO 4 and stoichiometric lithium tantalate. The suggested scheme enables broad wavelength tuning by simply tilting the crystal.
Abstract:
The present invention employs a beam steering apparatus to isolate valuable cells from others cells, tissues, and contaminants. In one embodiment, the system balances optical trapping against flow to parallelize cell sorting under the flexible control of computer program-directed traps which differentially manipulate cells based on their composition or labels to direct separation.
