Abstract: Properties of a sample that are dependent upon wavelength, such as IR absorption, can be detected and deconstructed into wavelets or other basis functions. These basis functions can be compared to determine which have a relatively high likelihood of being noise or signal, and an attenuation factor can be applied to each wavelet. A spectrum can be reconstructed from these wavelets that exhibits a significantly higher signal-to-noise ratio than raw data co-adding would produce in significantly less measurement time.
