Claim:
1. A distribution analysis device that analyzes a distribution of a field having a property satisfying the Laplace equation, the distribution analysis device comprising: an obtainment unit configured to obtain measurement data indicating the distribution of the field measured through a sensor sensing area, the sensor sensing area being an area that moves in a measurement area where the distribution of the field is measured and being an area in which the field is sensed as an aggregate; and a calculation unit configured to calculate analysis data indicating the distribution of the field with a higher resolution than the measurement data, using an arithmetic expression that is obtained by deriving a solution of the Laplace equation using a boundary condition that an integral of the solution of the Laplace equation in a finite interval corresponding to a size of the sensor sensing area matches the measurement data, wherein the obtainment unit is configured to obtain the measurement data indicating the distribution measured through the sensor sensing area that rotates about a line parallel to a predetermined Z direction, and in the case where: a three-dimensional space is represented by cylindrical coordinates using z that denotes a coordinate value in the Z direction, θ that denotes an angular coordinate, and p that denotes a radius distance; k denotes a wavenumber in a P direction which is a direction of the radius distance; Δz denotes the size of the sensor sensing area in the Z direction: g as the arithmetic expression.
