Abstract: Apparatus for registering the spectral signature of a dynamic source event include an imaging-sensor array configured to register electromagnetic energy over a predetermined range of electromagnetic wavelengths and an optical system configured for imaging onto the imaging-sensor array a dispersion pattern of electromagnetic energy emitted from a source event external to the optical system. The optical system includes (i) a focusing element and (ii) a selected set of optical dispersion apparatus. Among the optical dispersion apparatus are at least a first optically dispersive element that disperses a first selected set of wavelengths within the sensitivity range of the imaging-sensor array and at least a second optically dispersive element that disperses a second selected set of wavelengths within the sensitivity range of the imaging-sensor array such that wavelengths emitted from a source event that are within the first and second selected sets of wavelengths impinge simultaneously upon the imaging-sensor array along, respectively, a first extrapolated axis and a second extrapolated axis that is non-parallel to the first extrapolated axis.

Abstract: An exemplary embodiment of apparatus and method to measure and filter the spectrum of electro-magnetic radiation using multiple dispersive elements, such as diffraction gratings or VIPA etalons, concatenated in a cross-axis orthogonal arrangement can be provided. For example, it is possible to receive at least one first electro-magnetic radiation and generate at least one second electro-magnetic radiation using at least one first spectral separating arrangement. A first spectrum of the second electro-magnetic radiation can be dispersed along at least one first dispersive axis with respect to a propagation direction of the second electro-magnetic radiation. In addition, it is possible to, using at least one second arrangement, receive the second electro-magnetic radiation and produce at least one third electromagnetic radiation having a second spectrum dispersed along at least one second dispersive axis with respect to a propagation direction of the third electromagnetic radiation. The orientations of the respective first and second dispersive axes can be different from one another. The first and/or second dispersive arrangements can be VIPA etalon arrangements.

Abstract: For spectrally filtering at least one input beam, a first reflective element is configured to tilt to multiple tilt orientations that each corresponds to a different angle of propagation of at least one input beam. One or more optical elements are configured to change at least some of the relative angles of propagation of the input beam for different tilt orientations of the first reflective element. A spectrally dispersive element is configured to receive the input beam at a location at which the central ray of the input beam is incident at different points on the spectrally dispersive element for each of the tilt orientations, and configured to disperse spectral components of the input beam at different respective angles in a spectral plane. The first reflective element is configured to tilt to select at least one and fewer than all of the dispersed spectral components to be directed to a selected output path.

Abstract: A refractive spatial heterodyne spectrometer includes an input aperture for receiving an input light; a collimating lens for collimating the input light into a collimated lightbeam; and a beamsplitter for reflecting one part of the collimated light into a first arm and transmitting another part of the collimated light into a second arm. The first arm includes a first dispersing prism for receiving and refracting the first part of the collimated light, and a first mirror positioned to reflect the refracted first collimated light back through the first dispersing prism and to the beamsplitter as a first light wavefront. The second arm includes a second dispersing prism for receiving and refracting the other part of the collimated light, and a second mirror positioned to reflect this refracted light back through the second dispersing prism and to the beamsplitter as a second light wavefront. The beamsplitter transmits a portion of the first light wavefront and reflects a portion of the second light wavefront into an output optics section to inferometrically combine into an interference image, and a detector receives the interference image and outputs an interference image pattern.

Abstract: There is provided spectral discrimination apparatus for use in a scanning optical microscope, the spectral discrimination apparatus comprising dispersive means (31) and frequency selective means including a rotatable disc (36) or discs. The discs are formed with apertures or spiral slots which, on rotation of the disc or discs, controls the frequency of light transmitted by the apparatus. The apparatus includes a detector (39) for receiving light from the frequency selective means. The, or each, rotatable disc (36) is positioned at an aperture plane after the dispersive means (31), although this is not essential if the rotatable disc has its outer periphery shaped to provide a cam surface engaged by a cam follower. There is also provided a method of spectral discrimination in a scanning optical microscope, comprising dispersing the light and passing the light through frequency selective means in which the form of rotating discs controls the frequency of transmitted light.
