The influence of an external electric field or temperature on holographic scattering from holographic polymer-dispersed liquid crystals
(H-PDLCs) was investigated experimentally. The auto-generated parasitic gratings are affected by an externally applied electric field in a
similar manner as the elementary grating. We find that the threshold voltage, switching-on and -off times are independent on the grating
vector. On the contrary, the suppression level of the refractive-index modulation is proportional to the spatial frequency. Heating of the
sample reduces the strength of parasitic gratings analogously to the case of an external electric field.
