System and method for multiplex spectroscopic imaging

Optical detection apparatus, comprising:

• a) a plurality of optical sensors configured to provide respective electrical signals corresponding to respective incident electromagnetic radiation;
• b) a plurality of resonant amplifiers corresponding to respective optical detectors, each resonant amplifier operative to amplify portion(s) of the respective electrical signal having a selected temporal frequency and to attenuate portion(s) of the respective electrical signal not having the selected temporal frequency;
• and
• c) a disperser adapted to receive light and distribute a respective selected portion of an optical bandwidth of the received light to each of the plurality of optical sensors.

A method of analyzing constituents of a sample, the method comprising:

• contemporaneously irradiating the sample with incident radiation including narrowband light and broadband light;
• while irradiating the sample, modulating optical power of the narrowband light or the broadband light at a selected temporal frequency;
• dispersing wavelengths of resultant light from the sample across a plurality of optical detectors;
• and
• filtering respective signals from the optical detectors to provide a spectrum dataset of the sample, the spectrum dataset including signals corresponding to the selected temporal frequency.
