  • Optical fstop/resolution apparatus and method for specified depth-of-field
    Patent number: 6389229
    Abstract: A method and apparatus to determine the fstop that provides optimal image resolution for a predetermined depth-of-field. An approximate and exact method and apparatus are provided to determine the optimal resolution fstop. The optimal resolution fstop is a function of the lens focal length, depth-of-field in front of the object, wavelength of light, and distance of the object to the lens center. Once the optimal resolution fstop is determined, the camera is adjusted to the closest discrete fstop available. When the approximate field technique is utilized, the camera must be adjusted to the discrete fstop closest to, but not exceeding, the computed fstop.
