摘要：
The invention relates to an optical phantom that is suitable for simulating the optical properties of biological material and to a method of producing said phantom. The phantom is comprised of a matrix of poly(vinyl alcohol) (PVA) and spherical particles whose refractive index differs from that of the PVA. Preferably the PVA has a level of hydrolysis of >98%. Preferably the spherical particles are hollow polystyrene particles. In addition, light-absorbing and light-scattering substances may be added to the matrix.
