A compact long-wavelength near-infrared IOT node and its performance experiments
Abstract:A compact long-wavelength near-infrared (LW-NIR) IOT node based on linear variable filter was presented. The LW-NIR spectral data can be collected and transferred with wireless communication method. Performance experiments were carried out to test the parameters of the node, such as wavelength range, spectral resolution, wavelength accuracy and stability. Experimental results demonstrate that the wavelength range is from 950nm to 1700 nm, and the spectral resolution is approximately 1% of peak wavelength. The wavelength accuracy and wavelength stability are less than 1.3 nm and 0.1 nm respectively. The proposed node can meet the demand of near infrared spectral analysis in IOT applications.
