Abstract

The invention provides a solid material reverse reflection characteristic measuring device and relates to the technology of precise measurement of solid material reverse reflection characteristics. The solid material reverse reflection characteristic measuring device aims at solving the problem that an existing method is large in measuring result error when used for measuring solid material reverse reflection characteristics. A laser emitted by a laser device is shot into a first port of an optical fiber circulator, the laser shot out of a second port of the optical fiber circulator is collimated with an optical fiber collimator and then shot to the surface of a solid material to be measured, the laser reversely reflected by the surface of the solid material to be measured is collimated with the optical fiber collimator and then returns to the second port of the optical fiber circulator, the laser shot out of a third port of the optical fiber circulator is shot to the detection surface of a photoelectric detector, the solid material to be measured is located in a light shielding cylinder, and the light shielding cylinder is located on a rotary tray. The solid material reverse reflection characteristic measuring device can measure laser energy in the micro-solid angle direction, and is high in measuring precision, easy to operate and suitable for optical measurement and laser active detection.

Description

technical field [0001] The invention relates to the field of optical measurement technology and laser active detection technology, in particular to the precise measurement technology of the retroreflection characteristics of solid materials. Background technique [0002] The reflection characteristics of the solid surface are the basic parameters for the calculation of surface-related radiation heat transfer and radiation detection, such as the analysis and calculation of radiation heat transfer in the boiler furnace, the analysis of radiation heat transfer in the engine engine, the performance analysis of the solar concentration system, the radiation heating and drying system, Radiation temperature measurement and ground object remote sensing all need to use the reflection characteristic parameters of the material surface, use the surface reflection characteristic parameters directly for heat transfer analysis, or use the surface reflection characteristic parameters as the b...
