Multi-spectral laser sensor based on code-division-multiplexing techniques

A multi-spectral laser sensor using the orthogonal code-division multiplexing technique is applied to measure the optical properties of biological-like turbid media. Measurement of the total attenuation coefficient of Intralipid was obtained for wavelength from 0.65 to 1.55 /spl mu/m, which is the l...

description A multi-spectral laser sensor using the orthogonal code-division multiplexing technique is applied to measure the optical properties of biological-like turbid media. Measurement of the total attenuation coefficient of Intralipid was obtained for wavelength from 0.65 to 1.55 /spl mu/m, which is the longest near-IR wavelength measured for this material, giving an empirical fit of /spl lambda//sup -2.43/. The advantage of CDM techniques against interference was demonstrated by simulating the detection of a contaminant is cow milk under rapid agitation.
