Measurement of atmospheric refractive index structure constant near ground based on CAN bus

摘要：

The principle of measuring atmospheric refractive index structure constant was introduced, and the specialities of the CAN bus were described. A system based on CAN bus was developed to measure the atmospheric refractive index structure constant in the open air and transmit the multi-parameter data from micro-thermal probe and weather transmitter for over 30m far through a 4-wire cable. Continuous measurements for weeks have been taken, and daystart and sunset, the two weakest periods of the atmospheric turbulence, have been found on the experiment spot, and the regular pattern of the terbulence at different heights has been achieved. These results supply necessary information for the laser propagation experiment near earth surface and show that the system is practical and effective for the multi-parameter measurements and transmissions in the field.
