| Popis: | This paper shows the relevance of the developed spectrophotometer for the study of optical bleach and organic dye for different tissues. The paper presents a block diagram of the spectrophotometer and provides technical and operational characteristics of the device. Diffuse reflection spectra were obtained for different tissue samples, which show that the optical bleach forms a short-wave absorption band at λ ≤ 420 nm and gives a luminescent additive to the reflected radiation flux in the blue region of the spectrum λ ≈ 430–480 nm. In the region of λ ≈ 500–640 nm, the reflection coefficient decreases. A quantitative comparison of the brightness parameter B determined from the R(λ) spectra and the brightness parameter B of the white tissues was performed. The results of Be measurements were reduced to the reference value Br by linear interpolation. The interpolation error did not exceed δB ≤ 1 %. The color parameters for the X, Y, and Z coordinates were measured with an error of no more than 1 %. The diffuse reflection spectra of colored tissue samples are analyzed and the results of measurements of colorimetric coordinates are obtained. |
