| Popis: | The influence of special multislit diaphragms placed in front of the receiver cathode on the signal value and signal-to-noise ratio in acoustooptical visualisation of scattering biological media is studied. Using such diaphragms the visualisation of a bulk lightabsorbing and sound-transmitting object in the form of a rectangular parallelepiped with the size 5 × 5 mm in the plane, perpendicular to the laser beam axis, and with the size 2.5 parallel to this axis is carried out. The object was merged into scattering media of thickness Lc = 62 mm along the direction of propagation of the optical radiation with the parameter μLc varying from 0 to 46 (μ being the extinction coefficient of the medium). |
