Spatial resolution, spectral contrast and occlusion are three major bottlenecks for non-invasive inspection of complex samples with current imaging technologies. We exploit the sub-picosecond time resolution along with spectral resolution provided by terahertz time-domain spectroscopy to computationally extract occluding content from layers whose thicknesses are wavelength comparable. The metho...

introduction: contrast sensitivity is one of the most important psychophysical tests that may be used for the evaluation of refractive state of eye and retinal image quality. yellow vs. blue color contrast sensitivity may be more suitable in this regard. materials and methods: thirty myopic eyes were considered in this study. yellow vs. blue color contrast sensitivity was evaluated under the sa...
