Abstract

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.
