  We analyze the shadow of charged stationary axially symmetric space-time
(Kerr-Sen dilaton-axion black hole). This black hole is defined by a mass $M$,
a spin $a$ and $r_{\alpha}=Q^{2}/M$, where $Q$ is the electric charge. Shadows
are investigated in two conditions, i) for an observer at infinity in vacuum
and ii) for an observer at infinity in the presence of plasma with radial
power-low density. In vacuum, the shadow of this black hole depends on charge
and spin parameter. We can see that, increasing electric charge, $Q$ decreases
the size of shadow. Also, increasing spin parameter $a$ decreases the size of
shadow. However, in existence of plasma, parameter of plasma like refraction
index, $n$, playing an important role on shadows. In fact, decreasing
refraction index decreases the size of shadow.
