Popis:	We present preliminary results on the performance of a basic stand-off Raman spectroscopy setup using coded apertures compared to a setup using a round-to-slit fiber for light collection. Measurements were performed using single 5 ns laser shots at 355 nm with a target distance of 5.4 meters on ammonium nitrate powder. The results show an increase in signal-to-noise ratio of 3-8 times when using coded aperture multiplexing compared to the fiber setup.
