Classic holography, tomography and speckle metrology using a high-power terahertz free electron laser and real-time image detectors

Experiments with in-line and two-beam holography as well as speckle photography and speckle interferometry using highpower monochromatic radiation of free electron laser have been carried out. An experimental-and-theoretical approach to tomography with monochromatic terahertz sources is presented. All measurements were carried out using real-time image sensors: a microbolometer focal plane array and a luminescence-quenching thermal image plate with intensified CCD camera.
