Embodiment Construction
[0030] The three-dimensional reconstruction system of the gas-liquid two-phase flow field based on laser scanning of the present invention includes a computer (1), a vibrating mirror controller (2), a vibrating mirror (3), a laser (4), and a parabolic reflector L1 (5) , plano-concave cylindrical lens L2 (6), high-speed camera (7), optical filter F1 (8), measuring pipeline (9) and gas-liquid two-phase flow (10).
[0031] During specific implementation, the laser (4) selects a continuous laser with a wavelength of 532nm. The measuring pipe (9) is transparent and made of acrylic material, the liquid phase of the gas-liquid two-phase flow (10) in the measuring pipe (9) is added with fluorescent substance rhodamine B, and the lens of the high-speed camera (7) is equipped with a long-wavelength sensor with a wavelength of 570nm. pass filter (8).
[0032] During specific implementation, the computer (1) is connected to the vibrating mirror controller (2) and the high-speed camera (7...
