Abstract
Chemical imaging is demonstrated by using an innovative near infrared spectrometer that uses a digital micro-mirror array device (DMD) to provide both spatial and spectral resolution. Hadamard transform spectroscopy is used to enhance the signal-to-noise ratio of the measurement compared to single point raster scanning. The concept is demonstrated by collecting a spectral image of a polymer sample composed of separate regions of polystyrene and polypropylene. The resulting image is composed of 63 spectral resolution elements across the first overtone region of the near infrared spectrum (1538-1818 nm), as well as 65 spatial resolution elements across the longitudinal direction of the DMD (11.3 mm).
