Acquisition and Application of Multimodal Sensing InformationWith the development of advanced sensors in modern science and technology, sensors have already penetrated into such fields as industrial production, space development, ocean exploration, environmental protection, medical diagnosis, biological engineering, and even cultural relic protection. Sensors are the basis of all data acquisition. Almost every modern project, from the exploration of the vast universe and ocean, to the complex engineering systems, is inseparable from a variety of sensors. Sensors convert physical parameters (e.g., temperature, pressure, humidity, speed, etc.) into signals that can be measured electrically. A high-performance sensor with the advantages of high sensitivity, high resolutions, and real-time observation is desirable. In addition, the application of computers and advanced signal processingsignal-processing methods makes sensor management possible. The use of sensing data from multiple sensors has been proven to be an efficient way to improve service experiences in different IOT IoT fields, e.g., intelligent transportation, remote sensing, smart city, and UAVs.
Recently, various optical sensors develop rapidly with the help of the advanced light source. For example, the laser spectroscopy-based trace gas sensor exhibits excellent sensitivity and selectivity compare compared with the electrochemistry gas sensor. The laserLaser radar or scanner are widely used in target detectingdetection, tracking, aiming, and imaging recognition since the extremely high resolution in frequency domain, space domain and time domain. Therefore, it is meaningful to set up a Research Topic for the acquisition and application of multimodal sensing information.
