摘要： Quantum resonance fluorescent microscope systems for detecting component substances in a specimen are described. The systems are based on exciting the sample containing the material with a femtosecond to nanosecond probe pulse of collimated light, which is tailored to optimize detection of a given material by separating the probe pulse into component features of frequency, polarization, phase and/or amplitude. The component features are independently shaped and formed into a composite pulse selected to optimize a signature response pulse received from the material. In some cases, two independently re-shaped pulses are combined, where one re-shaped pulse has two mixed polarization states and the other re-shaped pulse is linearly polarized These two pulses are made to intersect at an angle of 90 degrees so that the combined pulse has electric field in each of the XYZ axes. Selection of the appropriate shapes for the component features of the pulses for a given material is accomplished by testing variations in the features on the material, assigning a fitness value to variants that tend to optimize a distinctive spectral response from the material, and using a genetic algorithm to select the combination of component features that enhances the distinctiveness of the response received over a typical background.

摘要： L'invention concerne un procédé de réalisation d'images holographiques par enregistrement d'un réseau de pixels (202) qui forment ensemble une image composite à deux ou à trois dimensions. Chaque pixel correspond à un échantillonnage uniquement des rayons qui devraient traverser un point donné (205) situé à la surface d'un hologramme normal. A l'aide de ce procédé, on peut réaliser n'importe quel type d'hologramme courant, y compris les hologrammes à deux et à trois dimensions, les images stéréoscopiques et les hologrammes en couleurs. Chaque pixel est un hologramme visible à la lumière blanche produit en enregistrant un petit hologramme à proximité de la partie la plus étroite d'un faisceau de rayons convergents de lumière cohérente (520), chaque rayon correspondant en général à un point situé sur l'objet, et les rayons dans un pixel étant confinés dans un plan horizontal entrecoupant la surface de l'objet.

摘要： Methods and systems for projecting wave fields use a diffusing medium, a wavefront shaper, an illumination source, and a control system. A system for projecting an object wave field into a projection volume includes a wave scatterer, a wave field projector configured to project a wave field onto the wave scatterer, and a controller coupled to the wave field projector. The controller is configured to cause the wave field projector to project a wave field that, upon interacting with the wave scatterer, is redirected to form an object wave field that forms a predetermined pattern in the projection volume.

摘要： A method is disclosed for making holographic images by recording an array of pixels (202) which together form a two or three dimensional composite image. Each pixel corresponds to a sampling of just those rays which would pass through a given point (205) on the surface of an ordinary hologram. Every common type of hologram can be made by this method, including 2D/3D holograms, stereograms, and full color holograms. Each pixel is a white light viewable hologram generated by recording a small hologram near the narrowest part of a converging bundle of rays of coherent light (520), usually with each ray corresponding to one point on the object, and the rays in a pixel being confined to a horizontal plane intersecting the surface of the object.
