  • Patent number: 10190910
    Abstract: An optical filter is disclosed including two laterally variable bandpass filters stacked at a fixed distance from each other, so that the upstream filter functions as a spatial filter for the downstream filter. This happens because an oblique beam transmitted by the upstream filter is displaced laterally when impinging on the downstream filter. The lateral displacement causes a suppression of the oblique beam when transmission passbands at impinging locations of the oblique beam onto the upstream and downstream filters do not overlap.

  • Patent number: 10018834
    Abstract: A method and apparatus for performing foci array scanning using at least one adjustable or tilting medium is disclosed. The medium can be controllably tilted in order to translate a beam of electromagnetic radiation perpendicularly to its propagation, and upon exiting the medium, will propagate in the original, incoming direction. This allows the apparatus that emits the radiation, such as a laser, to remain stationary and still scan a 2D array. Additionally, the reflected fluorescence light undergoes the opposite shift to “reverse” the scanning shift and bring the beamlets back in line with a lenselet array. So the collection fibers can remain static and collect light from different spots on the sample from during the scan.

The plurality of self-interfering signals can provide an interference pattern used to reconstruct the emitted light spectrum. A second plurality of interferometers may output a second plurality of self-interfering signals to reconstruct a low resolution spectrum of the input light signal satisfying the Nyquist criterion. Low resolution signal components can be detected from the low resolution spectrum and used to pre-process the interference pattern.

    Abstract: A surgical imaging device and method configured to be inserted into a surgical site. The surgical imaging device includes a plurality of prongs. Each one of the prongs has an image sensor mounted thereon. The image sensors provide different image data corresponding to the surgical site, thus enabling a surgeon to view a surgical site from several different angles. The prongs may be moveable between a first position, suitable for insertion through a small surgical incision, and a second position, in which the prongs are separated from each other. In addition, the prongs may be bendable.

  • Patent number: 9829435
    Abstract: A label-free biosensor detection arrangement incorporating an external cavity laser (ECL) includes a tunable lasing element (e.g. an antireflection coated laser diode or semiconductor optical amplifier) and a narrow bandwidth resonant reflectance filter as the wavelength-selective element for the tunable lasing element. A sample is deposited on the surface of the resonant reflectance filter containing a biological material. The wavelength emitted by the external cavity laser is continuously tunable by binding interactions between the biological material and the resonant reflectance filter or adsorption of the biological material present in the sample on resonant reflectance filter. The narrow bandwidth resonance reflectance filter can take the form of photonic crystal (PC), a Bragg stack, or a Brag fiber reflection filter.
