DOEMaster 2022a Release Notes<\/h3>\n

4\/10\/2022<\/h5>\n

\u2022\tNew Features:
\n\u2022\tAfter years research and development, LightSoft is proudly announcing world first commercially available CGH null lens encoding software, CGH Wizard feature, available in DOEMaster 2022a. CGH Wizard features LightSoft\u2019s Proprietary CGH encoding algorithm. With the help of CGH Wizard, the cost of CGH null lens can be driven down to a few hundred dollars from current price of thousands dollars. This cost reduction will greatly expand the application of CGH null lens in optical metrology and testing industry.
\n\u2022\tCGH Wizard\u2019s encoding algorithm is adaptive with respect to the local fringe period of the CGH to achieve the optimum encoding speed. It can automatically change the encoding step\/speed based on local fringe period of the CGH. The algorithm is also suitable for any size of the CGH, no additional field stitching algorithm\/software is needed. The size of the CGH is only limited to the memory size of the computer on which the CGH Wizard is running on. The encoding engine is coded in Fortran for fastest speed and fully parallelized with OpenMP to utilize all CPU cores of the computer. Most CGHs can be encoded within an hour. Another salient feature of CGH Wizard is that the generated GDS file size is about an order smaller compared to that of the GDS files generated by traditional encoding algorithms available in literature. This will save tremendous mask writing machine time and therefore could significantly cut down the writing cost of the CGH mask.<\/p>\n
