Abstract
A correlation interferometric spectroscopy devices are described that detect the spectral characteristics of a sample wherein device consists of an electromagnetic radiation source for exciting a sample with photons; and a detector adapted to detect an arrival time of a photon at the detector and further adapted to detect a delay between the arrival time of different photons. The device may further consist of an autocorrelator adapted to analyze the between the arrival of photons at the detector. The device may also be used together with other spectral detection and characterizing systems, such as Raman spectroscopy and attenuated total reflectance spectroscopy. Also provided herein are methods, systems, and kits incorporating the correlation interferometric spectroscopy device.
