  • Patent number: 10705020
    Abstract: A method for optical detection of residual soil in lumens of lumened or cannulated devices such as surgical endoscopes, after undergoing a decontamination process (e.g., a washing or rinsing operation). A soil detection system provides an indication of the presence of residual soil within a lumen by detecting luminescent radiation emanating from the soil on the interior of the lumen in response to excitation light.

  • Patent number: 6445508
    Abstract: An optical system for focusing an incident light so as to obtain a linear output (as a function of the wavelength, or of the order of diffraction, or of the grating spacial frequency or of the inverse of the index of refraction) comprises a diffraction grating and a lens, or a group of lenses, having a f-Sin(&thgr;) characteristic, where f is the effective focal length of the lens, or group of lenses, and &thgr; is an output angle of the light exiting from the diffraction grating. Therefore, a light incident on the diffraction grating reaches the lens, or the group of lenses, and results in a linear output. Using the present invention in a spectrometer reduces the time consuming calibration process required and renders it easier because of the linear output between wavelength and pixels positions. The lens, or group of lenses, has a diffractive, refractive or reflective property, or any combination thereof. The incident light can be a collimated, converging or diverging beam.

  • Patent number: 6025951
    Abstract: The invention relates to spatial light modulators (SLM) for amplitude and phase modulation of incident light. A "flexure" hinge which is provided between the SLM's substrate and micromirror comprises integral hinged sections which allow for the micromirror to tilt or to move in a piston-like fashion relative to the substrate in response to an electrostatic force. The hinge is particularly advantageous for large mirrors. In addition, the hinge can provide improved heat sinking capability over previously reported SLM hinge designs based on torsion bars and cantilever beams. The flexure hinge has sufficient mechanical flexibility that the SLM actuation voltage required is not excessively high. The flexure hinge has many applications, the preferred ones being a SLM for modulating high-energy beams and a SLM for optical channel switching.
