    Abstract: PURPOSE: To provide a multifocal point lens in which a light to each focal point, that is, light intensity to each diffraction sequence can be arbitrarily controlled uniformly or non-uniformly. CONSTITUTION: In a three focal point diffraction lens 20 which receives an incident light having a central wavelength λ, and limits three focal points, plural optical high positions and optical low positions are provided on the diffraction surface. Then, a difference between the highest optical high position and the lowest optical low position is substantially different from λ/2, and at least 20% of the incident light of the lens 20 can reach each focal point.

    Abstract: There is disclosed a diffractive optical element (11) and a method to produce same wherein the element comprises a base (13) and at least one phase zone (14) comprising an arbitrary multiplicity M of steps (22) of generally identical step height, wherein M is not a power of 2. The method includes the steps of defining a basic depth unit equivalent to a zone height divided by M, defining a depth sequence of N depths wherein N is the smallest integer greater than log2M such that each of the M steps can be produced by at least one linear combination of the N depths, defining N masks wherein each mask enables the optical element to be processed to one of the N depths and wherein for each mask, the steps to be processed are those which have the one of the N depths in its linear combination and serially utilizing each of the N masks for processing of the optical element.

    Abstract: In a secure imaging system for securing documents or encrypting images, an image comprises an array of printed positions formed using a group of inks each having a predetermined spectrum. The positions are selected to form a predetermined image, either real or virtual, when the image is viewed through an optical processor. An image formed using inks having the same colors as experienced by the human eye, but not sharing exactly the same spectra, will fail to form the correct predetermined image.
