    摘要： A mask for enhancing the depth of focus of an optical imaging system is designed by optimizing an optical property (transmittance or reflectance) of the mask relative to the intensity distribution in the system's image plane. Preferably, a desired PSF intensity is selected, a desired misfocus parameter range is selected, and the optical property is adjusted to minimize a measure of the departure of the system's PSF intensity, as computed from the mask's optical property, from the desired PSF intensity, over the entire misfocus parameter range. Most preferably, the desired PSF intensity is selected as the inverse Fourier transform of a desired OTF. Preferably, the mask is fabricated as a DOE.

    摘要： A method of extracting data from an identifiable monochromatic pattern. The method comprises separating a polychromatic optical signal, received from an object having identifiable monochromatic pattern, into a plurality of wavelength components, separately capturing each of the wavelength components, reconstructing a plurality of images each from a different wavelength component, detecting the identifiable monochromatic pattern in one or more of the images, and extracting data associated with or encoded by the detected identifiable monochromatic pattern. The images have different depths of field.

    摘要： Apparatus for image subtraction in order to extract non-common information from two light images comprises a TV camera tube including a photosensitive coating on its inner face and a grating on its outer face spaced from the photosensitive coating by the thickness of the tube; projectors for projecting the two light images simultaneously, from slightly different angles, onto the photosensitive coating via the grating such that the shadow of the grating interlaces the two light images on the photosensitive coating; and a scanner for electronically scanning the interlaced images on the photosensitive coating to produce a video output, and for processing same to select only the image information which is non-common to the two optical images.
