1. A miniature multi-spectral system comprising:
a first Fourier transform infrared (FTIR) miniature spectrometer to generate a first spectral output based on receiving a first light channel from a sample;
a second miniature spectrometer to generate a second spectral output based on receiving a second light channel from the sample;
a micro-electromechanical system (MEMS) infrared (IR) light source for the first FTIR miniature spectrometer;
a movable FTIR beamsplitter for a sample Fourier scan;
a beamsplitter actuator to move the movable FTIR beamsplitter by a distance d1; and
one or more processors coupled to the first and the second miniature spectrometers, wherein the one or more processors is configured to execute instructions to perform data fusion of the first and second spectral outputs, to generate fused data and to apply artificial intelligence (AI) of an AI module to the fused data to identify a pathogen, biomarker, or any compound from the sample.
