EFFICIENT MODULATED IMAGING

摘要

An apparatus for turbid sample measurement comprising a plurality of light sources for illuminating a turbid sample target area with non-spatial structured light, a projection system for illuminating the turbid sample target area with spatial structured light, a sensor for collecting light from the turbid sample target area, and a processor to analyze the data captured by the sensor to yield scattering and absorption coefficients of the turbid sample. A method comprises illuminating the sample with spatial structured light, collecting light reflected from the sample at a number of wavelengths, illuminating the sample with non-spatial structured light, collecting light reflected from the sample at a number of wavelengths, and combining the measurements of the collected light to obtain the optical properties of the sample and/or the concentration of absorbing or fluorescent molecules. The wavelengths of the spatial and non-spatial light sources are preferably different.
