ABSTRACT:
This invention provides a posture detecting apparatus capable of quickly determining, without depending on any complicated signal processing, which one of a plurality of reference postures a given human posture coincides with, or that it coincides with none of them.
Upon a hologram wherein images corresponding with a plurality of reference postures have been recorded by the help of the corresponding reference beams each having a different incident angle, focused is a beam which has been spatially modulated by the LCD (liquid crystal display) panel which has displayed the human posture to be detected. When the human posture in question coincides with one of the reference postures, from the hologram emanates a beam which takes the same path with that the reference beam corresponding with that reference posture takes for impinging on the hologram. A beam detector detects the beam emanating from the hologram.
