    Abstract: An optical device includes a waveplate sandwiched between first and second polarizers and is arranged to receive light emanating from an object or object image that is in motion relative to the optical device. A detector array includes one or more detector elements and is optically coupled to receive light from the second polarizer. Each detector element of the detector array provides an electrical output signal that varies according to intensity of the light received from the second polarizer. The intensity of the light is a function of relative motion of the object or the object image and the optical device and contains spectral information about an object point of the object.

    Abstract: A filter arrangement can transmit and/or reflect light emanating from a moving object so that the emanating light has time variation, and the time variation can include information about the object, such as its type. For example, emanating light from segments of a path can be transmitted/reflected through positions of a filter assembly, and the transmission functions of the positions can be sufficiently different that time variation occurs in the emanating light between segments. Or emanating light from a segment can be transmitted/reflected through a filter component in which simpler transmission functions are superimposed, so that time variation occurs in the emanating light in accordance with superposition of two simpler non-uniform transmission functions. Many filter arrangements could be used, e.g. the filter component could include the filter assembly, which can have one of the simpler non-uniform transmission functions. Time-varying waveforms from sensing results can be compared to obtain spectral differences. The filter arrangement, in a practical commercial embodiment, can be manufactured to be disposable, and used in a point-of-care device for use practically anywhere, at low cost, and can also be implemented in an in-line monitoring system.

    Abstract: An implantable product such as an article, device, or system can include analyte and non-analyte containers in parts that can be operated as optical cavities. The product can also include fluidic components such as filter assemblies that control transfer of objects that affect or shift spectrum features or characteristics such as by shifting transmission mode peaks or reflection mode valleys, shifting phase, reducing maxima or contrast, or increasing intermediate intensity width such as full width half maximum (FWHM). Analyte, e.g. glucose molecules, can be predominantly included in a set of objects that transfer more rapidly into the analyte container than other objects, and can have a negligible or zero rate of transfer into the non-analyte container; objects that transfer more rapidly into the non-analyte container can include objects smaller than the analyte or molecules of a set of selected types, including, e.g., sodium chloride. Output light from the containers accordingly includes information about analyte.

    Abstract: A system is configured to determine a color distribution of an object moving along a flow direction relative to a spatial filter. The light emanating from the object is time modulated according to the mask features of the spatial filter. First and second detectors are arranged to sense the modulated light. The first detector senses light having a first wavelength spectrum and generates a first electrical output signal in response to the sensed light. The second detector light senses light having a second wavelength spectrum and generates a second electrical output signal in response to the sensed light. Signals from the first and second detectors include information about color distribution of the object.

    Abstract: A system includes a sensor network comprising at least two optical fibers coupled to a pavement. Each optical fiber includes one or more optical sensors installed a predetermined distance from one or more adjacent optical fibers. The one or more optical sensors are configured to produce a wavelength shift signal. A processor is configured to determine one or both of one or more attributes of one or more objects travelling on the pavement and a traffic condition of the pavement based on the wavelength shift signal. A transmitter is configured to transmit the one or more attributes to a predetermined location.
