1. Application Concepts Monitor or Heads Up Display Full Scene Selected Zoomed ROI Multiple Fisheyes for Full Surround View A Staring Full Scene Imager with Simultaneous Optical Zoom For Surveillance and Tactical Applications Janet E. Shields and Richard W. Johnson Scripps Institution of Oceanography, University of California San Diego Multiple Fisheye systems with zoom for full sky and terrain Supplement existing optical and acoustic sensors Tanks Full Surround View Using multiple lenses Vehicle remains buttoned up while viewing full surround. User actively chooses area to zoom. Minimizes laser eye safety issues Surveillance For military and civilian Threat-sensitive Sites Motion Detection enables automated designation of ROI Automatically controls alarms and peripheral sub-systems Littoral Zone Covert Surveillance Moored system deployed By covert insertion vehicle Unattended Ground Sensors Three images would be combined electronically for full scene view. Any image could be zoomed using prisms to select scene in near-real-time. Two or three fisheye lenses With prisms to image full surround Mockup for Conceptual Evaluation Proprietary U. S. Patent Pending UCSD 2003-249 Full Scene: Optical Resolution Target in LabFull Scene Radiometrically Enhanced to Show Resolution Target Partial Optical Magnification of Fisheye’s Image Plane Close-up of the Optically Zoomed Target Image High Optical Magnification of Fisheye’s Image Plane A Novel System (patent pending) to enable Covert, Fast Surveillance One or more 180 degree lenses monitor the full surround Novel optics are used to magnify the image plane A high resolution view of a selected ROI is created The full scene view and zoomed ROI are shown simultaneously Concept is in development stage All significant elements have been tested in mock-up configuration A Full Scene view and Magnified ROI are shown simultaneously Target image from a single fisheye lens is split to create two identical image planes One image plane is shown in full scale Second image plane is imaged again with magnifying optics Magnifying optics retains detail (high spatial frequency) lost in normal electronic zoom ROI designated interactively or automatically Rotating Dove prisms enable fast selection of region for zoom Readily Adaptable for Multiple Applications Can monitor complete surround, unlike mechanical zoom lenses Robust and covert: no external moving parts Retains detail lost in electronic zoom Can respond to user interaction or motion detection algorithms Can be developed potentially for daytime, nighttime, visible, or IR Can automatically control alarms and peripheral subsystems Prisms are used to create two image planes. One is used for behind-the-lens zooming. User simultaneously views full field and selected region. Electronic Zoom for comparison with optically zoomed ROI Multiple Dove Prisms are used for fast imaging of Region Of Interest Photo courtesy of Sierra Pacific Corp.
