Abstract: A spectrograph having multiple excitation wavelength ranges is disclosed. The spectrograph can include a wavelength switching mechanism to switch between different wavelength ranges in accordance with the wavelength of an incoming light signal. The wavelength switching mechanism can include multiple optical assemblies (or elements) corresponding to the different wavelength ranges for processing the incoming light signal. The mechanism can also include a switching component for switching the optical assemblies to align the appropriate assembly with the incoming light signal. Each optical assembly can include one or more transmission gratings to disperse the incoming light signal into multiple wavelengths within a particular wavelength range and a reflecting mirror proximate to the grating(s) to reflect the wavelengths of light back through the grating(s) to photodetectors for measuring to wavelengths to generate a light spectrum. The spectrograph can be used in Raman spectroscopy.

Abstract: This invention relates to a wavelength tunable spectrometer and a wavelength tuning method thereof, and more particularly to a wavelength tunable spectrometer and a wavelength tuning method thereof which are capable of providing the highest efficiency of wavelength of applied light without replacement of a diffraction grid or without operation of an observed portion. According to embodiments of the present invention, since a spectrum of incident light can be obtained with the optimal diffraction efficiency based on a wavelength of the incident light without motion of a camera for observation and replacement of a diffractor by rotatably arranging a transmission type diffractor to provide an incidence angle to provide the optimal efficiency for a selected wavelength of an external light source to be observed and arranging a mirror to provide light, which is changed in its diffraction angle depending on rotation of the transmission type diffractor and the wavelength of the incident light, on the same output light path irrespective of a change in the rotation of the transmission type diffractor and the wavelength of the incident light, it is possible to reduce a size of the spectrometer, product cost and possibility of failure.

Abstract: A detection system comprising detection processing means, spectral discrimination means, and temporal tracking and declaration processing means which cooperate to detect and declare a missile launch. A spatial filter isolates discrete spectral features in an image from a detector array. The discrete spectral features must pass a threshold, which may be adaptive. In a spectral discrimination step, the pixel-to-pixel separation for those pixels passing the spatial filter step is compared to a predetermined pixel spacing. The predetermined pixel spacing is determined from the optical setup and a spectral feature of interest that is contained within the emission from, for example, an ignited rocket motor or other fired projectile. In a temporal step, the pixels that have met the other criteria are tracked as candidate detections, which are declared a threat if they display characteristics of a moving threat, e.g., a MANPADS missile, RPG, mortar or the like.
