Abstract

The invention discloses a device and method for detecting optical property parameters of agricultural products in a continuous spectrum. A light source is installed on a light source moving device, a spectrograph is connected to a rotary connection ball cover of an integrating ball through an optical fiber, a sample table, the light source moving device and a ball cover opening-and-closing device are connected with a motion control box, and the spectrograph and the motion control box are connected to a computer. A light source part, the integrating ball and the ball cover opening-and-closing device are installed on the same straight line, it is guaranteed that the ball cover of the integrating ball can be attached to a light beam outgoing opening of the integrating ball, and an optical fiber cladding cylinder and a light beam incident opening of the integrating ball are coaxial. A sample clamping hole installed in the sample table can be coaxially moved between the light source part and the light beam incident opening of the integrating ball or can be coaxially moved to the light beam outgoing opening of the integrating ball. The value of the total reflectivity Rt and the value of the total transmittance rate Tt are measured, and the values and the value of the fixed anisotropy coefficient g are combined to be substituted into a reverse multiplication algorithm to calculate and obtain the optical property parameters. According to the device and method, a halogen tungsten lamp is used, more optical property information can be obtained, and detection accuracy is improved.

Description

technical field [0001] The invention relates to a device and a method for measuring the optical properties of biological tissues, a device and a method for detecting the optical property parameters of agricultural products under continuous spectrum. Background technique [0002] Near-infrared spectroscopy is widely used in the quality inspection of agricultural products and food. However, due to the limitation of the principle of the method itself, the traditional near-infrared spectroscopy analysis technology can only measure the concentration of substances contained in the sample (ie chemical composition), but cannot obtain the physical structure information of the sample. [0003] With the development of laser applications in the field of biomedicine, the optical properties of biological tissues gradually appear in people's field of vision. The main parameters are the absorption coefficient and the scattering coefficient, which are used to describe the absorption and scat...
