In this paper, a method on how to design and implement a miniaturized spectrometer with low-light-level (LLL) CCD on
GaAs is introduced. The optical system uses a blazed grating as the dispersive element and a 1×64 CCD on GaAs as the
sensor. We apply a highly integrated Cortex-M4 MCU (STM32F407), to build the data acquisition and analysis unit,
providing Wi-Fi interface to communicate with the PC software. It can complete the tasks like data acquisition, digital
filtering, spectral display, network communication, human-computer interaction etc.
RS (Remote Sensing), GIS (Geographic information System) and ES (Expert System) are used in many fields. They are powerful tools for obtaining, organizing, analyzing and displaying spatially referenced data, estimating resources, providing relevant information and so on. So their introduction to marine fisheries is essential to take sustainable development of marine fisheries in east China Sea into reality and improve marine fisheries management in China. Based on the marine fisheries information, using Geographic Information System and Expert System, we have established the Chinese Marine Fisheries Remote Sensing Information Service System. This system started in 1997. It extended the application of the advanced technology such as GIS, RS, ES to marine fisheries. In this paper, the recent works and improvement are introduced.
