Popis:	This paper reports a two channel, coherent holography receiver for the measurement of the two dimensional reflector profile of the 30 m millimeter radio telescope at Pico Veleta, Spain. Using a phase and frequency locked Gunn oscillator as local oscillator, a path length difference of 30 ?m can be measured.
