[en] we report on the experimental realization of digital holography
at 140 GHz using terahertz detectors based on field-effect transistors (FET).
We demonstrate that the hologram signal can be efficiently recorded by the
FET detector at room temperature. The digital reconstructions of amplitude
and phase objects are presented. Owing to the possibility for FET array
integration and massive production, potential towards fast scan
nondestructive testing application is discussed.
