A microscopic imaging system includes a receiving means () for receiving an article () to be imaged, a linear optical detector (), focussing means () for focussing an image of an article in the receiving means onto the detector, scanning means () for producing relative movement between the image and the detector in a direction substantially perpendicular to the axis of the detector, and an optical correcting element () for reducing aberrations in the image focussed onto the detector.

Microscopic imaging system having an optical correcting element

A method and apparatus for generating a beam of light having extended depth of focus. The apparatus comprises, for instance, a binary phase mask that generates a diffraction pattern including a bright main ring and a plurality of side-lobe rings, an annular aperture mask that passing only a portion of the diffraction pattern, and a lens that causes light passing through the annular aperture to converge toward and cross an optical axis. Where the converging light crosses the optical axis, constructive interference takes place, thereby generating a beam of light that has extended depth of focus.
