  • the light source 14 is arranged so that that of it emitted light on the top 20 and bottom 22 passes through the liquid container 12 and on a Projection screen 24 falls.
  • Such optical auxiliary elements are made of known in the art, so at this point this should not be discussed in more detail.
  • the actuator 16 is with the liquid container 12 operatively connected. A movement of the actuator 16 is thereby transferred to the liquid container 12. By the movement so forced becomes the liquid 18 in the liquid container 12 vibrated. at suitable choice of the oscillation frequency of the actuator allow resonances to be forced into training standing waves in the liquid 18 are used can.
  • the liquid container should be in the position of use 12 are essentially horizontally aligned, so that the liquid 18 has an approximately uniform thickness and approximately perpendicular to the light source 14 can be shined through.
  • Such a vibration pattern can be generated by means of a control unit 26 the actuator 16 can be specifically specified.
  • the light passing through the liquid 18 gives up the projection surface 24 the appearance of the wave pattern again since it is on the phase boundary between the liquid 18 and the air broken accordingly becomes.
