Classification: CPC A  G | IPC A  G

Claim 13:
14. The acousto-optic imaging system as claimed in claim 13, in which the control device is configured for calculating the demodulated signal Sm(t) by inverse Fourier transform of a signal Šm(ν), with:

{tilde over (S)}m(ν)={tilde over (S)}0m0(ν)+{tilde over (S)}1m0(ν)+{tilde over (S)}−1m0(ν)  (17),

where:

{tilde over (S)}0m0(ν)=¼[{tilde over (S)}m0(ν)+{tilde over (S)}m1(ν)+{tilde over (S)}m2(ν)+{tilde over (S)}m3(ν)]  (14)

{tilde over (S)}1m0(ν)=¼[{tilde over (S)}m0(ν)−{tilde over (S)}m2(ν)−i({tilde over (S)}m1(ν)−{tilde over (S)}m3(ν))]  (15)=

{tilde over (S)}−−1m0(ν)=¼[{tilde over (S)}m0(ν)−{tilde over (S)}m2(ν)+{tilde over (S)}m1(ν)−{tilde over (S)}m3(ν))]  (16)

the terms Šmj(ν) are the time-domain Fourier transforms of the measurement signals Smj(t),
j is an integer in the range of 0 to 3,
ν is the time-domain frequency.
