  • Patent number: 8084755
    Abstract: Methods and apparatuses for determining the depth and concentration of fluorophores in a turbid medium are disclosed. The method advantageously provides for a rapid estimation of the depth of the flurophore using characteristics of a temporal point spread function. The concentration of the flurophore can be determined using the method of the present invention by combining a calculated depth of the flurophore with a measurement of the intensity of the emitted fluorescence. The intensity can be accurately measured by the apparatus disclosed herein which combine back-reflection and trans-illumination geometries for the source of light injecting and detection.

  • Publication number: 20110183370
    Abstract: An optical detection system for identifying target bacterial cells in a food sample, comprising a first fluorescent nanoparticle dye labeling specifically the target cells. A second fluorescent dye reacts non-specifically with all bacterial cells. An imaging unit optically excites the fluorescent dyes and captures images of the sample for each of two different wavelength bands emitted as a result of the excitation of the dyes. A processing unit identifies the target cells from the sample and comprises an image processing unit for processing the images of the sample. A target cell identifier identifies the target cells in the images by detecting individual units present at a same location in both of the processed images. An output unit provides data related to the identified target cells in the sample. A method is also provided.

  • Patent number: 7855376
    Abstract: An object-detecting lighting system comprises a light source emitting visible light. A source controller is connected to the light source to drive the light source into emitting the visible light in a predetermined mode. An optical detector is positioned with respect to the light source and is adapted to detect the visible light as reflected/backscattered by an object. A data/signal processor is connected to the source controller and the optical detector to receive detection data from the optical detector. The data/signal processor produces a data output associated to the object as a function of the predetermined mode and the detection data.

  • Publication number: 20100312097
    Abstract: An apparatus for providing physiological information from an organism in disease diagnosis and treatment monitoring, for use in an MRI instrument. The apparatus operates on the concept of hybridized magneto-optical sensitivity. The MRI includes an MRI scanner and a controller for controlling the MRI scanner. The MRI scanner provides a magnetic field of at least 0.5T. The apparatus further includes a front end built of non-magnetic components, comprising light guides for illuminating a region of interest (ROI) and for collecting light emitted at said ROI; and a back-end comprising a light source for injecting light into said light guides; a light detector for receiving light collected at said ROI; and a processing and control unit for processing said light collected at said ROI.

  • Publication number: 20080309914
    Abstract: A method for detecting an object using visible light comprises providing a visible-light source having a function of illuminating an environment. The visible-light source is driven to emit visible light in a predetermined mode, with visible light in the predetermined mode being emitted such that the light source maintains said function of illuminating an environment. A reflection/backscatter of the emitted visible light is received from an object. The reflection/backscatter is filtered over a selected wavelength range as a function of a desired range of detection from the light source to obtain a light input. The presence or position of the object is identified with the desired range of detection as a function of the light input and of the predetermined mode.
