Abstract :
The concept of multi-channel RF complex refractive index measurement using a live electrooptic imaging (LEI) camera is proposed. The complex refractive index of water has been successfully evaluated with the transmitted microwave intensity and phase information being acquired within 0.5 s in a parallel manner suggesting that the instantaneous observation functionality of the LEI camera could be beneficial for prompt diagnosis and analysis of time-varying samples. The obtained refractive indices coincide well with those reported in the literature.
