Abstract:

By properly delaying the 50-nanosecond shutter of an image-converter camera with respect to a transmitted 60- nanosecond illuminating pulse from a Q-switched ruby laser, it is shown that the image formed may be limited to only those objects located in a certain range interval. Using this technique, it is shown that the visibility through atmospheric scattering mediums such as snow may be greatly increased. In addition, it is shown that the use of the technique enables range information to be added to an image such as the elevation contours in an aerial photograph. Author
