Multichannel Hadamard Transform Raman Microscopy

Volume 44, Number 1 (Jan. 1990) Page 1-4

Treado, Patrick J.; Morris, Michael D.


Spatial multiplexing is combined with multichannel detection in a Hadamard transform Raman microscope which provides 127 × 128 pixel images with 12 cm−1 spectral resolution. Spatial resolution of 0.6 μm per pixel has been achieved. A spatial multiplex advantage of better that 104 is demonstrated. Instrumental design details and spectroscopic images are presented.
