- Static two-dimensional aperture coding for multimodal, multiplex spectroscopyMichael E Gehm
Duke University Fitzpatrick Center for Photonics, Durham, North Carolina 27708, USA
Appl Opt 45:2965-74. 2006..We develop a general mathematical framework for deriving the required aperture codes and discuss several appealing code families. Experimental results validate the performance of the instrument...
- Performance comparison of aperture codes for multimodal, multiplex spectroscopyAshwin A Wagadarikar
Duke University Fitzpatrick Institute for Photonics, Box 90291, Durham, North Carolina 27708, USA
Appl Opt 46:4932-42. 2007..The SNR is least sensitive to vertical subpixel misalignments on the detector with a Hadamard-matrix-based code. Finally, the increased sensitivity of a spectrometer using a coded aperture instead of a slit is demonstrated...
