We present a frequency domain imaging system that allows for two-dimensional detection of phase and amplitude information up to 1 GHz. This is achieved by modulating the gain of an intensifier in front of a CCD camera that is operated in a homodyne mode. The system performance was investigated and characterized by taking measurements on optical tissue phantoms. Furthermore, we determined what modulation frequencies lead to the best signal-to-noise ratio in small tissue geometries, typically encountered in small animal and finger joint imaging.
