This model can be adopted to calculate the main spray characteristic parameters including spray penetration, overall and cross section Sauter mean diameter(SMD).

Study of beam parameters expression in laser heat treatment;

Analysis on the accuracy of beam parameter measurement by using CCD array;

A double integrating spheres system for measuring the optical properties of tissue was designed.

To obtain the optical properties of fruit materials a laser scattering imaging system was designed.

In this paper,the optical property parameters of fruit tissue,the models of optical transmissio.

The advantages and disadvantages between single integrating sphere system and double integrating sphere system for the measurement of optical property parameters of biological tissues were analyzed in detail.

Optical parameters of tissue was reconstructed by Genetic Algorithm and Monte Carlo method according to the multiple scattering photon distribution, which emerged when a collimated laser beam normally incident upon and propagated through the tissue.
