LASER SIMULATOR OF FIRE AND DESTRUCTION Russian patent published in 1995 - IPC

FIELD: laser devices. SUBSTANCE: laser simulator of fire and destruction comprises an optically-joined radiation source, a lens disposed on a weapon simulator, and a radiation receiver and a heating indicating unit. There is an additional variable- density light filter installed in front of the lens and the hitting indicator unit has the form of a threshold device. The variable-density light filter has the form of n circles with a common point of contact, the circle centers lie on a vertical straight line, the radii of n circles satisfy the relation r₁< r₂< r₃< ...< r_n and the transmission coefficients satisfy the relation τ₁> τ₂> τ₃>...> τ_n. EFFECT: simulating conditions are brought closer to real ones by entering the sighting angles. 2 cl, 6 dwg
