Spectral Interferometric Raman Imaging
Frontiers in Optics, 2005We propose a spectral interferometric Raman imaging technique to easily separate resonant and non-resonant Raman contributions. The technique combines three advantages desirable for microscopy namely, a single femtosecond laser, selective excitation, and complex susceptibility measurement.

Abstract A Raman spectrum of a solid contains information about its vibrational and electronic properties. Collecting spectral data with spatial resolution and encoding it in a 2D plot generates images with information complementary to optical and scanning force imaging. In the case of few-layer graphene the frequency of the G line and especially the

Analysis and experiments reported here show that Bragg imaging systems continue to operate at frequencies too low to support Bragg diffraction. At sound frequencies of a few megahertz and lower, Raman-Nath theory determines light diffraction by sound if the interaction length is no longer than about 35 cm.

Hadamard Transform Raman Imaging
Applied Spectroscopy, 1988Hadamard mask encoding allows medium to high spatial resolution imaging with unfocused laser beams. A laser beam is imaged on the sample through a series of masks. The spatially encoded signals from each of n masks, each containing n resolution elements, are measured. The spatial distribution of the signal is recovered by Hadamard transformation of the

Label-free Raman imaging is a noninvasive spectroscopic method for investigating the nature and distribution of molecular species within a sample. In this chapter, we describe the applications of conventional Raman imaging, as well as the related techniques of coherent anti-Stokes Raman scattering (CARS) and stimulated Raman scattering (SRS) imaging ...

Raman spectral imaging with resolution better than 1 nm has been achieved by a research team in China, delivering crisper details for chemists to analyze how single molecules behave. Until now, the best spatial resolution for the technique had been in the range of 3 to 15 nm.
