Abstract
A data processing method includes an input step Sof inputting measurement data into a neural network, an estimation step Sof generating estimation data from the measurement data, a restoration step Sof generating restoration data from the estimation data, and a calculation step Sof calculating a confidence level of the estimation data, based on the measurement data and the restoration data. The neural network is a trained model, the measurement data is data obtained by measuring light transmitted through an object, the estimation data is data of a three-dimensional optical characteristic of the object estimated from the measurement data, and the three-dimensional optical characteristic is a refractive index distribution or an absorptance distribution. In the estimation, the neural network is used, in the restoration, forward propagation operations are performed on the estimation data, and in the forward propagation operations, wavefronts passing through the interior of the object estimated from the measurement data are sequentially obtained in a direction in which light travels.
