Abstract

The invention relates to a multi-field sun photometer which comprises an industrial personal computer, a base box and an optical tracking platform. The industrial personal computer is internally equipped with an image acquisition card, a motion control card, an I / O control card and a signal acquisition card. The base box is internally equipped with modular power supplies, a motor driver, an I / O port driver circuit, a constant temperature controller and a signal gain control circuit. The optical tracking platform comprises a CCD detector, a stepper motor, a photoelectric detector, a constant temperature room, and tracking and signal light tubes. The image acquisition card and the CCD detector are connected through the modular power supplies. The motion control card is connected with the stepper motor through the motor driver. The I / O control card is connected with the photoelectric detector through the I / O port driver circuit, and the I / O control card is connected with the constant temperature room through the constant temperature controller. The signal acquisition card is connected with the tracking and signal light tubes through the signal gain control circuit. The double-tube multi-field sun photometer is of high measurement precision, and the intensity ratio of different fields can reflect the change in cloud condition.

Description

technical field [0001] The invention relates to a multi-field sun photometer. Background technique [0002] The current means of detecting cirrus clouds mainly include ground-based radar observation, satellite inversion and aircraft sampling. Due to the high cost of sampling by aircraft, the optical properties of cirrus clouds are mainly obtained by means of remote sensing. Based on the fact that the reflection of the non-absorbing channel in the visible light band is more sensitive to the cloud optical thickness, while the reflection of the water or ice absorbing channel in the near-infrared band is more sensitive to the cloud particle size, a method for inversion of cloud optical depth and effective particle radius has been developed. Because cirrus clouds are located from the upper part of the troposphere to the lower part of the stratosphere, and are usually optically thin (sometimes invisible to the naked eye on the ground), it has brought great difficulties to detecti...
