Abstract: An instrument including a scannable mirror employs multimode optical fibers and an optical coupler. Modal dispersion, e.g., from the multimode optical fiber, is reduced by a method employing deconvolution. The scannable mirror may employ a mirror movable in an optical waveguide or an optical fiber wound on an expandable core.

Abstract: Systems and methods for filter based spectrographic analysis are provided that permit rapid analysis of bioanalytes. Systems include devices for illuminating a sample with electromagnetic radiation and capturing radiation emitted from the sample. Emitted radiation can be collected by a plurality of waveguides each associated with a filter for a particular wavelength of radiation. Focusing devices are associated with filters and waveguides in certain embodiments. Radiation captured by waveguides can then be transmitted to a remote detector, which can determine the intensity of radiation for each waveguide. The use of a plurality of filters having different, band pass characteristics can permits the simultaneous detection of a plurality of different wavelengths of radiation emitted by a sample, thereby providing spectrographic information about the sample under study. Systems can include computers for storing acquired spectrographic information, addressable arrays of samples, and information security measures. Spectrographic information of samples can be diagnostic tools for identifying and quantifying a variety of different materials, including bioanalytes.

Abstract: A spectrometer system comprises (i) a slab waveguide characterized as an index of refraction higher than a surrounding medium, and having front surface and a rear surface opposite thereto, the front surface including a input portion for accepting optical radiation, a diffractor portion and an exit portion, (ii) a diffraction grating disposed on said diffractor portion of said front surface, (iii) a detector array aligned adjacent to the exit portion, and (iv) a mirror coated on the rear surface of the waveguide. Radiation transmitted within the waveguide from the input portion is reflected and collimated by the mirror to the granting. Light diffracted from the grating is dispersed to the mirror and reflected toward and through the exit portion and onto the array.
