We propose a fast magnetic resonance imaging (MRI) technique based on compressed sensing. The main idea is to use a combination of full and compressed sensing. Full sensing is conducted for every several slices (F-slice) while compressed sensing with high compression rate is applied to the rest of slices (C-slice). We can perfectly reconstruct F-slice images, which are used to roughly estimate the...
Ellipsometry is a widely used technique to characterize surface of thin films and materials. We propose a new method to obtain ellipsometric parameters in real-time and simultaneously as a pair of images. Our method consists of two components: a rotating polarizer and an analyzer, and a correlation image sensor for demodulation. We show a theoretical analysis of the system. We show several experimental...
