A Linear CCD Spectrometer Based on FPGA for Light-source Characterization

摘要

We report on the implementation of a FPGA-based ultra-violet (UV), infra-red (IR) visible (Vis) CCD spectrometer using a linear CCD detector operating at room temperature. The host interface is high-speed USB for data exchange with high-level environments such as Visual Basic, MATLAB and LABVIEW. The high-resolution intensity versus wavelength output is 8-bit digitized for secondary processing using a semi-flash analogue-to-digital converter (ADC) capable of sustained sampling rates of 20Mb/s.
