Binary Complementary Filters for Compressive Raman Spectroscopy [PDF]
Applied Spectroscopy, 2017 The previously described optimized binary compressive detection (OB-CD) strategy enables fast hyperspectral Raman (and fluorescence) spectroscopic analysis of systems containing two or more chemical components. However, each OB-CD filter collects only a fraction of the scattered photons and the remainder of the photons are lost.
