Abstract
We present a simple, very compact, and inexpensive spectrometer for diffuse source spectroscopy using only a volume hologram (recorded by two spherical beams) and a CCD camera (or a detector array). We show that this spectrometer can operate well under spatially incoherent light illumination. We also show that the resolution of this spectrometer can be optimized by proper selection of the location of the CCD camera (or the detector array). The results show the possibility of using optimized holographic optical elements as the integrated collimating, dispersive, and light-collective components of spectrometers.
