摘要: Abstract Optical scattering spectra and angular distribution of intensities were evaluated using concentrated orange juice. The juice was opaque due to the particles included. In these specimens, varies with refractive index ratio against liquid surrounding particles. sugar concentrations juice, which are linearly correlated can therefore be measured by their distributions. a halogen lamp, white LED, yellow red LED near-infrared LEDs (λ = 850 nm 940 nm) vary specimens. gradient correlation coefficient calibration lines fitted found angles, θ. A non-destructive evaluation sensitively at θ = 170 or 160 °s any incident lights scattered from
