Paper Abstract

With the recent technological advances, there is an increasing need for testing the microstructure of objects. We show here Digital Holographic Microscopy (DHM) that implements digitally the principle of holography. It is particularly well suited for recording and reconstructing three-dimensional objects. In this paper, we present an off-axis digital holographic configuration and address some basic issues of the off-axis lensless Fourier transform digital holography including the recording conditions and the methods to improve the imaging performance. Following the theoretical analysis, the simple imaging system with the off-axis arrangement is built. Through using the resolution test target as microscopic object, the recorded holograms are reconstructed digitally based on the principle of Fresnel diffraction. The experimental results are consistent with the theoretical analysis. In addition, from the experimental operations and the design of reconstruction procedure we can see that the off-axis lensless Fourier-transform digital holographic setup is simple and suitable for real-time applications in microscopy.
