Information × Registration Number 0125U001789, ( 0226U000470  ) R & D request Title To improve and investigate methods for eliminating defects in diffractive elements fabricated by direct laser writing Head Dmytrenko Oleh O., Registration Date 21-03-2025 Organization Institute for Information Recording NASU popup.description1 The improvement of methods for detecting and removing defects on the surface of modulation disks obtained by direct laser recording is the main objective of this study. To achieve this, an analysis of the defect size distribution will be conducted, the causes of the formation of darkened areas in images will be investigated, and methods for removing opaque defects using focused laser pulse irradiation will be developed and studied. The expected results of this work will contribute to enhancing the quality and reliability of modulation disks during their manufacturing and operation. popup.nrat_date 2025-03-21 Close
