Baker, Designer of High-Altitude Camera Lenses, Dies at 90 By JEREMY PEARCE [snip] 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."
