A method to measure the three-dimensional deformation of fabrics by using an optical microscope tomography using magnified projections with various illumination directions is proposed. The CT reconstruction of the optical microscope tomography was simulated with a test phantom. A good image reconstruction was obtained with the test phantom (x:128×y:128×z:64 voxel) using a conjugate gradient algorithm with nonnegative constraint. To obtain good images reconstruction by using the optical microscope tomography, it is necessary that the number of projections is 12 or over and illumination directions are at an angle of 20 degrees or over to the optical axis of the optical microscope, and it is more desirable that the digital camera has 4096 different brightness levels (12bit) or over.
