    Multi-wavelength digital in-line holographic microscopy
    (2012-01-01) Velaquez, D.; Garcia-Sucerquia, J.; Universidad EAFIT. Departamento de Ciencias Básicas; Óptica Aplicada
    The use of multiple wavelength illumination in digital in-line holographic microscopy is presented. A biological sample is illuminated sequentially with three different optical sources and the separate holograms reconstructed with the appropriate wavelength. For controlling the scale of the reconstructed holograms, a reconstruction algorithm that allows for choosing the pixel size at the reconstruction plane independently of the wavelength and the reconstruction distance is used. The method is illustrated with experimental results. © OSA 2012.
