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