High Sensitive Smartphone based Raman System based On Cloud Network Architrcture in NS2

Raman spectroscopy has been increasingly researched this year. Due to the high accuracy, fast speed, and nondestructive detection features of Raman spectroscopy, there are more and more application scenarios. In this paper, a smart phone Raman system is studied. By the optical path design and slit coupling technology, the sensitivity of the device is improved while the size of the spectrometer itself is reduced. In order to improve the detection speed and accuracy, a cloud network architecture is proposed. The spectrometer is integrated into the backside of a smart phone and the wireless communication function of the smart phone can be used to realize the connection with the cloud server. The device terminal is only responsible for collecting and uploading data to the cloud. Spectra are identified by the algorithm server. The result and the attributes files are then transmitted to the smart Raman terminal. The algorithm, database, and terminal equipment are separated from each other to facilitate the timely update of algorithms and databases.
