    "abstract": "The holographic imaging of rigid objects with diode lasers emitting in many\nwavelengths in a sillenite Bi12TiO20 photorefractive crystal is both\ntheoretically and experimentally investigated. It is shown that, due to the\nmulti-wavelength emission and the typically large free spectral range of this\nlight source, contour fringes appear on the holographic image corresponding to\nthe surface relief, even in single-exposure recordings. The influence of the\nnumber of emitted modes on the fringe width is analysed, and the possible\napplications of the contour fringes in the field of optical metrology are\npointed out.",
