PURPOSE: Holography system for a sound mirror is provided to photograph source of sound by a camera, to monitor the source of the sound into a monitor unit and to detect position of the sound source for removing the sound. CONSTITUTION: Holography in a sound mirror comprises a sound mirror(11) collecting sound wave of a sound source(10) in a vehicle; a micro phone(12) combined to the sound mirror; a traverse(13) moving the sound mirror to measure the sound source; a workstation(14) analyzing data measured by the traverse; a speaker(15) outputting a signal from the data analyzing workstation; a CCD(Change Coupled Device) camera(16) photographing a vehicle by being mounted on a front side of the micro phone; and a monitor unit(17) monitoring the image photographing portion through the traverse by being mounted on the CCD camera. Thereby, the holography in the sound mirror detects position of the sound source for removing the sound.
