| 20100278521 | Fourier telescopic imaging system and method - A system and method for imaging far away fast moving objects such as satellites in low earth orbit.

At the same time a flood beam illuminates the entire target and reflected speckle is also recorded by the same camera to provide the necessary object spatial frequencies. The illumination patterns are sequenced in time, stepping through offset phase shifts to provide data necessary to reconstruct an image of the target from the recorded reflected light. The reference spot phase and amplitude are then reconstructed, and the reference spot's complex field is then digitally interfered with the flood illuminated speckle field by use of a special algorithm. In order to obtain a high resolution 3D image of the target, a second measurement is acquired with the laser beam slightly shifted in frequency to second color. | 02-23-2012 |

By collecting a series of images, and demodulating them at the various beat frequencies, the downshifted spatial frequencies can be identified, correctly up-shifted, and fitted together with a set of special Fourier transform based algorithms to reconstruct high-resolution images. Applicants have performed laboratory experiments that this invention can provide resolution substantially better than diffraction limited resolution. | 05-03-2012 |

| 20080278719 | WAVELENGTH DEPENDENT REFLECTIVE SAMPLE SUBSTRATES FOR RAMAN AND FLUORESCENCE SPECTROSCOPY - A material which is generally transparent in the visible region of the spectrum but reflective at laser wavelengths reduces undesirable, substrate-induced Raman and fluorescence scattering. A substrate provides a surface for supporting the sample, with the material being disposed between the surface of the substrate and the sample.

The output(s) are linear or nonlinear combinations of the peak heights or areas, coupled with weighting factors which relate the raw inputs to a quantitative output such as concentration of a chemical species. Each specific input can use a different type of averaging. The overall goal may be optimization for best precision, and/or optimization for minimum lag time. | 11-26-2015 |
