A coupling device for an optical fiber used in optical tomography examination of a medium includes a mass of diffusing material for a wavelength guided by the optical fiber. This mass includes a bearing surface to be applied against the surface of the medium. At least one housing is provided in the mass to receive the end of the optical fiber.

Method and device for diffuse excitation in imaging

A phantom for medical imaging instrumentation, the phantom including a first hydrogel matrix, said matrix containing additives for simulating the optical and acoustic properties of a living organ or tissue. In the phantom, the additives include Indian ink or haemoglobin, silica powder and titanium dioxide powder. The phantom may contain a tumor simulator in solid or liquid form. It may also comprise several hydrogel matrices, each matrix including additives in different concentrations depending on the organ or tissue simulated. A method of producing the phantom includes one or more freeze-thaw cycles for optimizing the characteristics of the phantom.

Bimodal organ phantom and associated production method

Method and device for measuring the multi-dimensional distribution of optical characteristics of an object, by carrying out the following operations:

Method and device for measuring optical characteristics of an object

An optical device intended for the analysis of a scattering medium, including at least one light source distant from the scattering medium and capable of providing an incident light beam intended to illuminate the scattering medium; at least one sensor capable of detecting a radiation emitted by the scattering medium; a support of the scattering medium at least partially non-absorbing for the incident light beam and the scattered radiation. All or part of the support is formed of a scattering material having a decreased scattering coefficient greater than 0.1 cmand smaller than 700 cm.
