The invention provides a mountain town space and traffic diversified feature data processing method, and relates to the technical field of electric digital data processing, remote sensing data is collected at different sampling heights, building features and traffic features of mountain town are extracted, hierarchical clustering is performed on all the building features and traffic features, and the data of the mountain town space and traffic diversified features is obtained. Obtaining a building feature cluster set and a traffic feature cluster set; determining reward heterogeneity of the mountain cities and towns in the spatial dimension under different sampling heights based on a feature reward mechanism of reinforcement learning; performing spectral difference analysis on the remote sensing data at different sampling heights to obtain spectral response differences; and determining a reward factor of multivariate feature enhancement through reward heterogeneity and spectral response difference, and fusing all remote sensing data according to the reward factor to obtain fused features of mountain urban space and traffic distribution. By adopting the scheme of the invention, enhanced fusion of multi-element features at different sampling heights can be realized, so that the accuracy of mountain town space and traffic feature analysis is improved.

This invention discloses an all-fiber integrated electro-optic crystal electric field probe and demodulation device. The electro-optic crystal electric field probe includes: a polarization-maintaining fiber, a first glass sleeve, a second glass sleeve, a collimating lens, a quarter-wave plate, an electro-optic crystal, and a reflective film. The polarization-maintaining fiber is fixedly connected to the first glass sleeve, the first glass sleeve is fixedly connected to the second glass sleeve, the polarization-maintaining fiber is connected to the collimating lens, the collimating lens is connected to the quarter-wave plate, the quarter-wave plate is connected to the electro-optic crystal, and the electro-optic crystal is connected to the reflective film. The collimating lens and the quarter-wave plate are disposed inside the second glass sleeve. This invention solves the problems of unstable electric field measurement caused by the difficulty in integrating space optical elements, susceptibility to vibration, large size, and difficulty in coupling, and improves the sensitivity and stability of the measurement device.
