Abstract:
1. Apparatus for registering the spectral signature of a dynamic source event, the apparatus comprising: 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 including (i) a focusing element and (ii) a selected set of optical dispersion apparatus including 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.
