Let us change the phase difference so that I 1 = I 2 . If the phase shift had to be
increased to do this, i.e., δ > 0, then the point 2 was mere remote after the shift than
point 1.
The double-pulse ruby laser radiation is used in this complex for recording a
double-exposure hologram. To control the functional state of the patient during the
investigation, “Impecard” software and hardware complex is used, which displays
the information on the computer.
A sync pulse is formed with the synchronization system in the needed phases of
the cardiac cycle in the moments of time set by an operator. The sync pulse launches
the ruby laser.
The chest of a patient who sits in the special chair is evenly illuminated with the
optical system of illuminating beam formation. The scattered radiation is recorded
on the hologram with two reference beams obtained using the system of formation
