Early Acoustic Films
between 1997 and 2004

Between 1996 and 1999 the overlay of (optical) photo and acoustic map occured manualy using CorelDraw. The array included a centered laser-pointer, to give the direction of negative z-axis (right hand rule). After 1999, acoustic photos and films were produced with automatic image overlay (USB-camera in the array). In the last years it become possible to overlay acoustic film and video film automaticaly.
