Abstract

A novel method of holographic color imaging for 3D spatially incoherent objects is proposed in this paper. Off-axis incoherent Fourier holographic recording of quasi-monochromatic illuminated objects is implemented by modifying the optical configuration of radial shearing triangular interferometer. Three holograms are recorded sequentially when the object is illuminated by red, green and blue color extended light and then synthesized to generate a RGB fashion color image. Holograms of different view of the object are recorded and reconstructed sequentially to achieve a holographic color imaging. Some image fusion skills are employed during the holographic reconstruction to compensate the chromatism and aberrations of the wavelength sensitively system. The method holds great potential in some applications such as high speed 3D spectral imaging.
