  • Phase Diversity and Polarization Augmented Techniques for Active Imaging
    Peter M. Johnson
    A firm understanding of the space environment is necessary to defend US access to space-based systems. Conventional imaging systems have been developed to gather information on space-based objects, but they are incapable of imaging objects in the earth’s shadow. In order close this gap in imaging-system coverage, an active-illumination based approach must be used. To facilitate...

  • Deviation of Time-Resolved Luminescence Dynamics in MWIR Semiconductor Materials From Carrier Recombination Theory Predictions
    Peter M. Johnson
    Time resolved luminescence spectroscopy was used to characterize luminescence decay curves for a bulk InAs sample and an InAsSb type-I quantum-well sample over the first 3ns following excitation. The luminescence decay curves were then converted to carrier densities and used to find recombination coefficients that provided the least-squared-error solution of the rate equation d...
