Japan, March 5 -- HAMAMATSU PHOTONICS KK has got intellectual property rights for 'PHASE DISTRIBUTION DESIGN METHOD, PHASE DISTRIBUTION DESIGN DEVICE, PHASE DISTRIBUTION DESIGN PROGRAM, AND RECORDING MEDIUM.' Other related details are as follows:
Application Number: JP,2022-036005
Category (FI): H01S5/04,H01S5/11,H01S5/18,H01S5/42
Stage: PROBLEM TO BE SOLVED: To provide a phase distribution design method with which it is possible to synchronize the phases of a plurality of optical images with each other.SOLUTION: In a second step, a real-space function 213 after an amplitude distribution 211 is replaced with a target amplitude distribution 214 is converted by Fourier transform B6 into a wavenumber-space function 223 that includes an amplitude distribution 221 and a phase distribution 222. In a third step, the phase distribution 222 of the function 223 is aligned to the phase distribution 222 of a function 223 in one phase modulation region among two or more phase modulation regions, the amplitude distribution 221 of the function 223 is replaced with a target amplitude distribution 204, and the function 223 is converted by inverse-Fourier transform B2 into a real-space function 233 that includes an amplitude distribution 231 and a phase distribution 232. Hereafter, the second and third steps are repeated while replacing the function 213 in the second step with the function 233. The phase distribution 232 of the function 233 having been inverse-Fourier transformed by the last third step is taken as the phase distribution of each phase modulation region.SELECTED DRAWING: Figure 13 (Grant)
