Abstract: A provided optical-phase-distribution measuring method, by which optical phase distribution is identified at high speed and with high accuracy from information on light-intensity distribution without using a special measuring device, comprises steps: for inputting light to be measured to optical systems, respectively, modulating the intensity and the phase, detecting the output light to be measured with CCD, and measuring the intensity distribution of detected light to be measured as an image with an optical-phase-distribution measuring system provided with the two different optical systems; for setting an observation equation, based on the intensity distribution and on the optical characteristics of the optical systems; for setting a phase-distribution identification inverse-problem from the observation equation, and formulating the set phase-distribution identification inverse-problem as a first nonlinear optimization problem in which complex amplitude representing the light to be measured is assumed to be a design variable; for converting the first nonlinear optimization problem to a second nonlinear optimization problem, in which expansion coefficients in a series expansion are assumed to be design variables, by series expansion of the phase distribution of the light to be measured; and for identifying the phase distribution of the light to be measured by solving the second nonlinear optimization problem.

Abstract: An image processing apparatus is disclosed which can produce refractive index distribution data with high accuracy without limiting directions in which transmitted wavefronts are measured. The image processing apparatus has a simulating section which simulates a transmitted wavefront in each of the directions to produce a second transmitted wavefront image based on first refractive index distribution data, a comparing section which produces first information indicating the result of comparison between the second transmitted wavefront image and the first transmitted wavefront image, and a changing section which changes the first refractive index distribution data based on the first information to produce second refractive index distribution data. In the apparatus, the processing in the sections is repeated using the second refractive index distribution data as the first refractive index distribution data to produce the resulting second refractive index distribution data which is used as the output refractive index distribution data.

Abstract: A laser beam emitted from a laser source is split by a beam-splitting means such as a beam sampler, and the power Q of the split beam is measured by a first detector. In addition, the power q1 of light that has passed through a pinhole while a DOE is not set is measured by a second detector, and the power ratio α=q1/Q is calculated. Then, the DOE is set and the power ratio βk=qk/Q, where qk is the power of each light beam, is calculated. The power ratio βk is evaluated on the basis of the power ratio α, so the optical properties of a diffractive optical element, in particular, in terms of diffraction efficiency in laser-beam diffraction and intensity uniformity of split beams can be measured with high accuracy.
