Many experiments in the terahertz region have been performed using low-power shot-pulse wideband sources. Appearance of more intense monochromatic terahertz sources (quantum cascade lasers, free electron lasers) and terahertz image sensors enables the implementation of classical variants of optical techniques in the terahertz range. In this paper we describe a series of experiments to demonstrate feasibility of classic holography at the terahertz range using the Novosibirsk free electron laser. Two imaging techniques have been applied for digital hologram recording. A modified MachZehnder interferometer has been fabricated for recording the reference-beam holograms. In-line holograms have been recorded and reconstructed
