Abstract
A simple, inexpensive, and efficient stabilized holographic recording setup is described which precludes the destructive fringe movement encountered in long-lasting holographic exposures. Utilizing a straightforward methodology, stability greater than ƛ/25 (recording wavelength ƛ=532 nm) for holographic recording sessions longer than 6 h can be achieved. Due to the software basis of this design, in the LabVIEW platform, the functionality of expensive hardware components is provided in software. Moreover, this setup is modularly designed and can be easily replicated for multiple labs, with the need only of the following hardware components: a piezo-shifting mirror, a computer, a data-acquisition card, and a photodetector.
