    Abstract: An optical imaging system and method for achieving a large depth of field without decreasing the relative aperture of an imaging lens. The imaging system has a light source for sequentially illuminating an object to be imaged with light of different ones of a plurality of wavelengths, and an imaging lens that has a focal length that varies with the wavelength of the light that illuminates the object. For each wavelength of light by which the object is illuminated, the imaging lens will image a different object plane onto an image receiving unit, and the image receiving unit will capture one well-focused, high resolution image of the object.

    Abstract: A disc serving as a spatial radiation modulator has dispersed radiation filters thereon. Each filter has a transmittance or reflectance modulation function of the form sin2(m&thgr;+p&pgr;/4), where m is a positive integer and p has one of the four values 0, 1, 2, 3. A radiation beam including selected wavelength components is diffracted into an elongated image dispersed according to wavelength. Different wavelength components are focused onto different filters on the modulator and are encoded by correspond filters. Since the modulation functions of the filters are orthogonal to one another, it is possible to extract the amplitude of each wavelength component after it has been encoded or modulated by corresponding filter from the total detected signal during one measurement.

    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: In embodiments, spectroscopic monitor monitors modulated light signals to detect low levels of contaminants and other compounds in the presence of background interference. The monitor uses a spectrometer that includes a transmissive modulator capable of causing different frequency ranges to move onto and off of the detector. The different ranges can include those with the desired signal and those selected to subtract background contributions from those with the desired signal. Embodiments of the system are particularly useful for monitoring metal concentrations in combustion effluent.
