Spatial-frequency domain imaging (SFDI)
SFDI is a method using near-infrared (NIR) light to generate wide field images (\>10 x 10 cm) of tissue optical properties (absorption and scattering coefficients) at sub-surface depths of 1-10 mm. With SFDI the tissue surface (skin) is illuminated by a rapid sequence of sinusoidal light patterns of varying spatial frequency and at different optical wavelengths. Collected camera images are then processed to yield maps of sub-surface optical properties.
