Abstract
A scanning device processes a multi-point simultaneous acquisition. The acquisition is processed for an infra-red diffuse optical tomography. An intensity modulated light is used with a frequency domain analysis theorem to obtain a reconstructed scanning image. The fibers are capable of a vertical movement and a radial movement. Thus, a precise image showing optical-information data is obtained with a low cost, even through scanning at a minimal angle.
