     J. G. Baker, Designer of High-Altitude Camera Lenses, Dies at 90
     In the late 1950's, with the launchings of the first satellites, Dr. Baker, 
    in collaboration with Joseph Nunn, developed the Baker-Nunn satellite
     tracking camera, which allowed observers to follow the course and 
    trajectory  of the Soviet satellite Sputnik in 1957. The camera uses an 
    expansive field  of view to photograph large swaths of sky and record the 
    progress of  satellites and other objects.
     Robert S. Hilbert, an optical designer and president of Optical Research 
    Associates, a design firm in Pasadena, Calif., said that the Baker-Nunn 
    camera provided "an unprecedented combination of speed, wide field of view 
    and image quality" and that, 45 years later, "for the same purpose, no 
    better camera or design exists than the Baker-Nunn today."
