METHOD AND SYSTEM FOR GENERATION OF A NEEDLE-SHAPED BEAM BY A DIFFRACTIVE OPTICAL ELEMENT FOR USE IN EXTENDED DEPTH-OF-FOCUS OPTICAL COHERENCE TOMOGRAPHY - A simplified explanation of the abstract
This abstract first appeared for US patent application 18447094 titled 'METHOD AND SYSTEM FOR GENERATION OF A NEEDLE-SHAPED BEAM BY A DIFFRACTIVE OPTICAL ELEMENT FOR USE IN EXTENDED DEPTH-OF-FOCUS OPTICAL COHERENCE TOMOGRAPHY
Simplified Explanation
The patent application is for a diffractive optical element that is made up of multiple unit cells arranged on a substrate. Each unit cell consists of multiple phase elements, with each phase element having a specific phase value. The phase values are determined by multiplying an incremental phase value by an index value. The index value ranges from 1 to N, and N is the total number of phase values. The diffractive optical element is designed to have M phase elements, where M is greater than 1. The innovation lies in the arrangement and characterization of the phase elements in the diffractive optical element.
Original Abstract Submitted
A diffractive optical element includes a substrate including a plurality of unit cells arrayed across the substrate. Each of the unit cells includes M phase elements and each of the M phase elements is characterized by one of a set of N phase values. Each of the set of N phase values is equal to an incremental phase value times an index m, wherein M>1 and m=1 . . . N.
