Abstract: Encoded spatio-spectral information processing is performed using a system having a radiation source, wavelength dispersion device and two-dimensional switching array, such as digital micro-mirror array (DMA). In one aspect, spectral components from a sample are dispersed in space and modulated separately by the switching array, each element of which may operate according to a predetermined encoding pattern. The encoded spectral components can then be detected and analyzed. In a different aspect, the switching array can be used to provide a controllable radiation source for illuminating a sample with radiation patterns that have predetermined characteristics and separately encoded components. Various applications are disclosed.

Abstract: Systems, methods and devices for holographic demultiplexing of optical signals that include constituent light signals of different wavelengths. A holographic demultiplexor includes a volume hologram having holograms for redirecting the constituent light signals. A dispersion element linearly disperses the optical signal, and the individual holograms of the volume hologram spatially reflect the constituent light signals back to the dispersion member at specific angles. The volume hologram spatially reflects the constituent light signals such that they are dispersed in two dimensions. The dispersion element then reflects the two dimensionally dispersed wavelengths to a two dimensional detector array.

Abstract: An integrated optical multiplexer and/or demultiplexer is provided for on-chip optical interconnection between electronic components on an integrated circuit chip and between chips, and for high density telecommunications. The multiplexer and/or demultiplexer includes an integrated circuit substrate formed with an array of photo detectors (for the demultiplexer) or photo emitters (for the multiplexer). Conditioning electronics is formed on the substrate and is coupled to the photo elements for conditioning electronic data for optical transmission in the case of the multiplexer or for conditioning optical signals into electronic data in the case of the demultiplexer. A first layer of optically transparent material is formed on the substrate overlying the detectors and/or emitters and a second layer of optically transparent material is formed on the first layer and functions as an optical waveguide. A binary blazed grating is formed at the interface of the first and second layers of optically transparent material. In use, discrete wavelength optical signals are modulated with data and emitted by the photo emitters. The discrete wavelengths are intercepted by the binary blazed grating overlying the emitters and multiplexed into a polychromatic beam for transmission through the waveguide. At the demultiplexer, the discrete wavelengths are separated by the binary blazed grating and directed to corresponding ones of the photo detectors. The conditioning electronics coupled to the photo detectors receives the output of the photo detectors, demodulates the output to extract the data, and formats the data for communication with electronic components on the integrated circuit.

Abstract: An optical arrangement has a light source which emits coherent light of a specific wavelength. Further provided is an optical Littrow grating, arranged at a specific Littrow angle &thgr;L. It has a multiplicity of parallel diffraction structures following one another periodically at an interval in each case of one specific grating period and arranged on a substrate predetermining a base area. The light wavelength, the grating period and the Littrow angle &thgr;L are tuned to one another in such a way that the grating is used in one of the largest diffraction orders m for light reflected back at the Littrow angle &thgr;L, which still fulfils the condition: (2(m+1)/m−1) sin (&thgr;L)≧1 An optical arrangement of this kind has an increased reflection efficiency.

Abstract: A disc serving as a spatial radiation modulator has dispersed radiation filters thereon. Each filter has a transmittance or reflectance modulation function of the form sin2(m&thgr;+p&pgr;/4), where m is a positive integer and p has one of the four values 0, 1, 2, 3. A radiation beam including selected wavelength components is diffracted into an elongated image dispersed according to wavelength. Different wavelength components are focused onto different filters on the modulator and are encoded by correspond filters. Since the modulation functions of the filters are orthogonal to one another, it is possible to extract the amplitude of each wavelength component after it has been encoded or modulated by corresponding filter from the total detected signal during one measurement.

Abstract: The invention relates to a spectrometer (10) with a dispersive element (16) that can be displaced between at least two positions. In the first position, the simply dispersed radiation (44) of a selected wavelength is reflected directly back in the incident beam path (42), while in the second position the dispersed radiation (32) of the selected wavelength can be directed to a reflective element (30) that is positioned such that the radiation (34) can be directed at least one more time across the dispersive element (16) and then back to the incident beam path (38). The spectrometer is provided with a device, for example, a mirror, an echelle grating or a prism that deflects the beam from the plane of dispersion, which is arranged in such a manner that the simply dispersed beam (34) runs in another plane than the multiply dispersed beam (36). The mirror (30) is inclined by an axis (54) that extends parallel to the plane of dispersion and perpendicular to the incident beam (32).

Abstract: An optical detection device for validating bank rates has several input apertures, an imaging device (12), a diffraction grating (15.1, 15.2, 15.3) associated with each input aperture (11.1, 11.2, 11.3) and a detection array (17).

Abstract: The present invention relates to different types of micromirror spectrometers using MEMS (Micro Electro Mechanical Systems) for various applications in the UV, VIS, NIR and MIR wavelength regions. The invention enables a wavelength selection using micro scanning mirror and integrated grating on a much smaller scale than previously encountered conventional diffraction grating monochromators. Especially small designs are obtained via simultaneous usage of collimation optics for both spatial filters, by using entrance and exit slit apertures, which are located very close together. Until now, the spatial filters themselves are not part of the miniaturization. The utilization of the precision from this technology allows for reproducible slits with defined geometries and surface roughness and accurate spatial classification towards the rotation axis of the diffraction grating. Therefore the assembly and adjustment effort of the monochromator is reduced. Due to the option of additional slit apertures, several independent monochromator channels with crossed beam paths can be created; whereas all remaining optical elements (diffraction grating and collimator optic) are utilized together. Such additional channels can serve, for example, as reference measurements of a radiation source, or enable the direct optical control of the grating torsion angle as a monitoring channel. The goal of the invention is to define a simple design and arrangement for monochromators based upon micromechanical elements, which avoids all disadvantages described above.
