We present a novel active imaging approach that
uses optimized wide band filtered illumination to obtain
multi-spectral reflectance information. Our optimization algorithm
utilizes light source and camera spectral information
in order to maximize the signal strength and the robustness
to noise. Through the use of active wide band illumination,
our system can obtain material reflectance information
in the presence of moderate (indoor) unknown ambient illumination.
Our method is very simple and does not require
special equipment. It can be used by photographers to obtain
material properties in uncontrolled environment and to
synthesize captured scenes under arbitrary illumination.
