Systems and Methods for Performing Compressive Spectral Measurements Using a Programmable Wavelength Filter

A spectroscopic system, comprising:

• a source for generating an electromagnetic radiation;
• a detector for detecting a light emitted from a sample;
• a programmable wavelength filter including multiple pixels for selectively directing the light emitted from the sample to the detector, wherein the multiple pixels form a plurality of pixel regions, and each pixel region is configured to direct the light of a same wavelength;
• a memory for storing instructions;
• and
• one or more processors communicatively coupled to the memory and configured to execute the instructions to:
• set the programmable wavelength filter to a first setting;
• irradiate the sample with the electromagnetic radiation;
• direct, via the programmable wavelength filter, a first portion of the light emitted from the sample to the detector, wherein at least one pixel region of the programmable wavelength filter includes a first non-zero number of pixels directing the light from the sample to the detector and a second non-zero number of pixels not directing the light from the sample to the detector;
• and
• detect, via the detector, the first portion of the light.
