Abstract :
In the light of future applications involving terahertz antenna measurements, this paper revisits Gabor (1949) holography as a direct method for recovering phase, offering some interesting advantages for near-field measurements. In particular, we examine the theory and parameterization of planar near-field Gabor holography and comment on the requirements for scanner precision at terahertz frequencies
