Abstract
The rise of the Internet of Things (IOT) spectral analysis technology has driven the development of near infrared spectroscopy sensors toward miniaturization, digitization and intelligence. A specific digitization research on InGaAs spectral sensor was reported to meet the digital and intelligent development of InGaAs focal plane Arrays (FPA). A new compact near infrared spectral node was developed integratedly with digital output spectral sensor circuit using self-developed analog to digital convertor (ADC) chip. The proposed node integrated 202 effective spectral channels with a wavelength range of 900 nm to 1 700 nm and a spectral resolution better than 16 nm. The wavelength accuracy and repeatability was less than 1 nm and 0.3 nm, respectively. The signal to noise ratio (SNR) of node system was about 500:1, and the frame scanning time was about 3 ms. The research results show that the compact IOT spectral node meets the practical application requirements of near infrared spectral analysis, and provides technical supports for the sensor on-chip digitization and IOT near infrared spectral analysis applications.
