Ice core optical characteristic reconstitution instrument and ice core optical characteristic reconstitution method

Abstract

The invention relates to an ice core optical characteristic reconstitution instrument and an ice core optical characteristic reconstitution method. The an ice core optical characteristic reconstitution instrument comprises a power supply, a main controller, a motor driver, a stepping motor, an industrial camera, an image processor, an optical analyzer, a constant temperature box and a light emitting table, wherein the power supply supplies power to the main controller, the motor driver, the constant temperature box and the light emitting table, the main controller controls the industrial camera to shoot an ice core and transmits a movement command to the motor driver, the motor driver controls the forward and backward movement and the stopping of the stepping motor according to the received movement command so as to control the shooting position of the industrial camera, the industrial camera, the image processor and the optical analyzer are sequentially connected, and the ice core images shot by the industrial camera are subjected to image splicing and optical analysis. According to the present invention, with the instrument and the method, the ice core image collection, the ice core image splicing and the optical analysis can be stably and reliably completed within only 2 min, and the reconstructed ice core panorama has advantages of large size and high resolution.

Description

technical field [0001] The invention relates to the field of optics, in particular to an ice core optical characteristic reconstruction instrument and method. Background technique [0002] At present, many sets of ice core optical measuring instruments have been developed abroad. In 2003, Japan has developed a set of ice core optical measuring instrument, which was applied in Dome Fuji ice core project II. The scanning speed of the optical measuring instrument is about 5mm / s, the length of the measured ice core sample is 1.5 meters, and it takes about 6 minutes to scan the whole ice core. The US National Ice Core Laboratory also developed a set of ice core optical measuring instruments in 2007. The scanning resolution of the ice core optical measuring instrument is 0.05mm to 1mm. It has the functions of automatic optical image acquisition and data processing. However, these devices are not resistant to the harsh environment of the arctic and can only be used in laborator...
