Abstract
Four real images were reconstructed from a coarsely sampled acoustical hologram made with an ordinary microphone. An internal reference was used which electronically simulated two plane reference waves impinging on the acoustical hologram plane at an angle of + and ‐42.55° from the perpendicular. The sound frequency was 20 kHz, with a wavelength of 0.676 in. in air.Keywords
