Abstract
An estimation system has a memory and a processor. The memory stores first wave front information and second wave front information. The first wave front information is information on the wave front that is obtained based on first illumination light that has passed through an object. The second wave front information is information on the wave front that is obtained based on second illumination light that has passed through the object. The wavelength at which the intensity of the second illumination light is highest is shorter than the wavelength at which the intensity of the first illumination light is highest. The processor performs an estimation process of estimating a three-dimensional optical property of the object. The three-dimensional optical property is a refractive index distribution or an absorbance distribution. The estimation process uses both the first wave front information and the second wave front information.
