    Abstract: An optical computing device includes a light source that emits electromagnetic radiation into an optical train extending from the light source to a detector. A substance optically interacts with the electromagnetic radiation. A processor array is positioned in the optical train and includes a plurality of integrated computational element (ICE) cores that optically interact with the electromagnetic radiation, wherein the detector receives modified electromagnetic radiation generated through optical interaction of the electromagnetic radiation with the substance and the processor array. A weighting array is positioned in the optical train and includes a plurality of weighting devices that optically apply corresponding weighting factors to the modified electromagnetic radiation. A broadband angle selective filter (BASF) array is positioned in the optical train to selectively pass electromagnetic radiation at a predetermined angle of incidence. The detector generates an output signal indicative of a characteristic of the substance.

    Abstract: An optical measuring system measures polarization optical properties of a sample. The system includes (a) a light source that emits measuring light along an optical axis of an analysis beam path, (b) a polarization state generator, arranged downstream with respect to the light source in the analysis beam path which provides light with a defined polarization state, (c) a sample holder, arranged downstream with respect to the polarization state generator in the analysis beam path which accommodates the sample, (d) a polarization state analyzer, arranged downstream with respect to the sample holder in the analysis beam path which measures the polarization state of the measuring light after passing through the sample, and (e) a mechanical support structure, at which at least the polarization state generator, the sample holder and the polarization state analyzer are directly attached. Also described is a method for producing such an optical measuring system.

    Abstract: An excitation light source emits excitation light to a target sample. An image sensor includes pixels arranged one-dimensionally or two-dimensionally, and receives measurement light from the sample according to the excitation light. A polarization selector arranged between the sample and image sensor includes pixels arranged one-dimensionally or two-dimensionally. Each pixel receives a corresponding portion of the measurement light, selects light having a polarization direction that corresponds to a driving signal applied to the pixels, and supplies this light to the image sensor. A measurement control unit supplies the cyclic driving signal having a first period T1 and acquires data I1, I2, I3, and I4 from each pixel of the image sensor for each exposure time segment T2=T1/4 obtained by dividing the first period T1 by 4.

    Abstract: A diagnostic device is provided that comprises a light source for transmitting a light beam through a blood sample to a light detector, and a permanent magnet, wherein one of the permanent magnet and blood sample is automatically movable relative to the other between a “HIGH” magnetic state position and a “LOW” magnetic state position, such that a substantially high magnetic field is applied to the blood sample causing any hemozoin in the blood sample to tend toward perpendicular orientation to the substantially magnetic field and the suppression, or enhancement of light based on its polarization, and a zero-to-near-zero magnetic field is applied to the blood sample causing the randomization of any hemozoin in the blood sample and a baseline amount of light to pass through the blood sample in the “LOW” magnetic state position.
