Abstract

In this paper, a real-time incoherent 3D imaging and display system using the modified triangular interferometer is optically implemented. The incoherent holographic system based-on this modified triangular interferometer employs the superposition of Fresnel zone patterns, in which the respective positions and intensities of the 3D object points are uniquely encoded and from this system the complex holograms without bias and conjugate images for the 3D object can be obtained. In addition, the real and imaginary parts of a complex hologram are obtained by subtracting and adding two hologram patterns. Then, illuminating them coherently and recombining the light passing through the transparencies by the use of the beam splitter allows the complex addition to be performed. Then, the desired 3D image is reconstructed through Fresnel diffraction. From some experiments with a 3D object of “dies”, it is found that the incoherent 3D imaging and display system without the bias and conjugate image can be optically implemented in real-time by using a modified triangular interferometer.
