The concept of optical reconstruction of digitally stored holograms

The progress in high resolution CCD detector technology provides the electronic medium for digital registration of holograms. This possibility is widely used in digital holography, which allows reconstruction of numerically stored microinterferogram. This approach is very useful for optical metrology application, however it is not convenient to real time visualisation of 3D object reconstruction. In the paper we propose to use only the stage of digital registration and then transfer these data to LCD matrix to form an optoelectronic version of microinterferogram. This hologram is reconstructed optically by a laser beam, giving possibility to visualise an amplitude-phase object's image. These procedures together with fast LCD and proper optical imaging system should enable to produce digital holographic films.
