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: In an optical spectrum analyzer comprising a spectrograph and a photodevice array, and an optical spectrum detecting method, a wavelength deviation, from an assigned wavelength, of a light detected by a photodevice array which detects a wavelength of a diffraction light or a non-diffraction light from an acoustooptic device, is detected and a feedback control to a diffraction angle of the acoustooptic device is performed. Also, without using a feedback control, an exit light and a diffraction light from the acoustooptic device are respectively received by two photodevice arrays and the photodevices are arranged in order to mutually compensate gaps between the photodevices, whereby a center of each photodevice is similarly made coincide with a peak of an optical beam to be received.

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). The diffraction grating (15.1, 15.2, 15.3) is rotated at angle of e.g. 45 degrees relative to the orientation of the linear detection array (17). This arrangement enables the spectra of multiple points to be measured simultaneously. The angle of rotation, the pitch of the apertures (11.1, 11.2, 11.3) and a pitch of the diffraction grating (15.1, 15.2, 15,3) are selected in such a way that the spectra of sad multiple points are contiguously mapped onto the detection array (17) has a single linear array of color sensitive detection pixels. The acxis of the linear array is offset with respect to an optical axis (7) of the optical detection device.

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.
