Abstract: A method and system of globally monitoring space weather conditions, use an imager, including one or more telescopic instruments and one or more processors, containing computer program code. The imager is configured on a platform; and positioned in the near Earth space environment, where, based on the executed computer program code, the imager compiles information about space weather conditions, by directly detecting electron emissions on a global basis. Network interfaces coupled with the imager provide, over a communications network, a plurality of communications and information, about space weather conditions, between the imager and a plurality of operational space assets and operational Earth assets. The plurality of communications and information about space weather conditions includes signals and information which automatically alert the plurality of operational space assets and operational Earth assets of effects of a solar wind.

Abstract: An apparatus and method for optically testing an object, such as an optical etector whose pixels are an array of optically sensitive charged coupled devices. Two mutually coherent beams of light are interfered on the object to form an interference fringe pattern of sinusoidally varying intensity of preselected spatial frequency. The object's response at this spatial frequency is used to determine one point of the object's modulation transfer function at that frequency. This is preferably done by using the device's output to infer the coherence function of the fringe pattern, taking the Fourier transform of the coherence function, and determining the amplitude of the function at the spatial frequency of the fringe pattern. The process can be repeated for different spatial frequencies until one determines the entire modulation transfer function.
