1. A measurement sensitivity calculation device comprising:
a calculating section that, in an object of measurement model that expresses an object of measurement, calculates measurement sensitivity per depth of the object of measurement by using, as the measurement sensitivity, an optical path length difference between a first optical path length expressing a length of a first optical path that is up to where light, which is emitted from a light emitter onto the object of measurement, is received at a first light receiver that is apart from the light emitter by a first distance, and a second optical path length expressing a length of a second optical path that is up to where light, which is emitted from the light emitter, is received at a second light receiver that is apart from the light emitter by a second distance; and
an outputting section that outputs the calculated measurement sensitivity per depth of the object of measurement, wherein:
the object of measurement model is a model expressing the object of measurement by a plurality of voxels, and the calculating section calculates the measurement sensitivity per depth of the object of measurement by, for each of the plurality of voxels, calculating the first optical path length and the second optical path length and calculating the measurement sensitivity, and integrating the measurement sensitivities calculated for the respective voxels per depth of the object of measurement.
