Latest Patents

Ueshima holds a patent for a "Method for measuring optical-phase distribution." This method allows for the identification of optical phase distribution by utilizing information on light-intensity distribution. The process involves several steps, including modulating the intensity and phase of the input light, detecting the output light with a CCD, and measuring the intensity distribution as an image. The method formulates a phase-distribution identification inverse-problem as a first nonlinear optimization problem, which is then converted into a second nonlinear optimization problem for effective identification of the phase distribution.
