Portable spectrometer

Abstract

The invention relates to a portable spectrometer, comprising a microprocessor, an optical system, a photodetector, an ADC analog-to-digital converter, a MMC interface, a USB interface, an LCD, a touch screen and an electric power source. Light to be detected goes through the optical system and is converted into analog signals by the photodetector; the ADC analog-to-digital converter converts the analog signals into digital signals, transmits the digital signals to the microprocessor and displays the spectrum data on the LCD; users can operate the spectrometer by the touch screen, the spectrum data can be either stored in a MMC card or transmitted to a PC by the USB interface. The spectrometer of the invention has the advantages that an embedded Linux operation system is adopted, device drivers of all parts are designed, so that users only need to develop an application software to complete relevant spectrum analysis and processing at an instrument end without having to know about concrete realization methods of bottom layer hardware; independent operation of collection, analyses and processing of spectrum can be realized in the absence of the control of the PC, thus facilitating operation and portability.

Description

technical field [0001] The invention relates to a portable spectrometer, which can be used independently without being controlled by a PC, and is suitable for researchers engaged in spectrum analysis. Background technique [0002] At present, all kinds of instruments and equipment are developing in the direction of miniaturization and intelligence, with a high degree of digital integration, but most of the spectrometer products transmit data in real time, that is, the spectrometer is directly connected to the PC through the data transmission interface. To control the use of the spectrometer, use the powerful functions of the PC to complete data storage and processing and analysis, so although there is great flexibility in the application software, it only needs to update and upgrade the corresponding software on the PC to meet the needs, but it is extremely It has greatly affected the portable operation and use of the instrument. Therefore, it is of practical significance t...
