Abstract: A holographic demultiplexor for filtering and spatially positioning individual optical channels, wavelengths, or sets of wavelengths. The holographic demultiplexor includes a volume hologram that includes holograms for redirecting wavelengths included in a light signal. A diffraction grating linearly disperses the light signal and the individual holograms included in the volume hologram spatially reflect the one or more wavelengths back to the diffraction grating as specific angles. The volume hologram spatially reflects the one or more wavelengths such that they are dispersed in two dimensions. The diffraction grating then reflects the two dimensionally dispersed wavelengths to a two dimensional detector array. The detectors of the detector array for adjacent wavelengths can be interleaved to reduce interference. Alternatively, the volume hologram can redirect sets of wavelengths directly to the detector array and the light is not linearly dispersed by a diffraction grating first.

Abstract: A method and device for improving a signal-to-noise ratio measurement range of a monitoring device operating on a fiber optic network. The method includes receiving a wavelength division multiplexed optical signal including a plurality of optical signals centered at different wavelengths within a range of wavelengths. The wavelength division multiplexed optical signal is dispersed to form a discrete power spectrum. The discrete power spectrum is measured, and data representing the measured optical signals is generated. The measured optical signals include a point spread function response of a pixelated optical detector. A deconvolution operation is performed on the generated data to create an estimate that is more representative of the power spectrum by compensating for the point spread function of the pixelated optical detector.

Abstract: A multi-color semiconductor lamp includes a semiconductor light source activable so as to generate a light output, a dispersing prism and a lens. The prism has an input side located in front of the light source to receive the light output, and an output side, and separates the light output of the light source into a plurality of chromatic components that radiate at different angles at the output side. The lens is disposed in front of the output side of the prism such that a vertex of a conical focusing region associated with the lens is located at the output side of the prism. The light source is activated when the spatial position of one of the light source and the prism relative to the other one of the light source and the prism has been varied such that a selected one of the chromatic components is registered with the conical focusing region of the lens. The semiconductor lamp can thus be controlled so as to generate different colored light outputs.

Abstract: A focal plane scanner having a front objective lens, a spatial window for selectively passing a portion of the image therethrough, and a CCD array for receiving the passed portion of the image. All embodiments have a common feature whereby the spatial window and CCD array are mounted for simultaneous relative reciprocating movement with respect to the front objective lens, and the spatial window is mounted within the focal plane of the front objective. In a first embodiment, the spatial window is a slit and the CCD array is one-dimensional, and successive rows of the image in the focal plane of the front objective lens are passed to the CCD array by an image relay lens interposed between the slit and the CCD array. In a second embodiment, the spatial window is a slit, the CCD array is two-dimensional, and a prism-grating-prism optical spectrometer is interposed between the slit and the CCD array so as to cause the scanned row to be split into a plurality of spectral separations onto the CCD array. In a third embodiment, the CCD array is two-dimensional and the spatial window is a rectangular linear variable filter ("LVF") window, so as to cause the scanned rows impinging on the LVF to be bandpass filtered into spectral components onto the CCD array through an image relay lens interposed between the LVF and the CCD array.
