Abstract
A method for observing deformation of an elastic material including rubber or elastomer, includes a first step of capturing projection images of at least a part of the elastic material from directions perpendicular to an arbitrary axis of the elastic material and a second step of constructing a three-dimensional image of the elastic material from the projection images. The first step includes deforming the elastic material in predetermined constant cycles, outputting capture signals at the same time points of the predetermined constant cycles, and capturing the projection images based on the respective capture signals.

A method for observing a deformation of an elastic material including rubber or elastomer, comprising:
- a projection image obtaining step of capturing a projection image of at least a part of the elastic material, from a direction perpendicular to an axis passing through the elastic material, at each of a plurality of capture positions around the axis,
- a three-dimensional image constructing step of constructing a three-dimensional image of said at least a part of the elastic material from the projection images respectively captured at said plurality of capture positions, and
- a step of displaying the constructed three-dimensional image,
- wherein:
- the projection image obtaining step comprises:
