spectroscopy and indispensable for the qualitative and quantitative interpretation of …

Infrared (IR) spectroscopic imaging seemingly matured as a technology in the mid-2000s,
with commercially successful instrumentation and reports in numerous applications. Recent …

IR spectroscopy is an excellent method for biological analyses. It enables the
nonperturbative, label-free extraction of biochemical information and images toward …

Infrared (IR) spectroscopic imaging systems are a powerful tool for visualizing molecular
microstructure of a sample without the need for dyes or stains. Table-top Fourier transform …

Optical microscopy for biomedical samples requires expertise in staining to visualize
structure and composition. Midinfrared (mid-IR) spectroscopic imaging offers label-free …

Infrared chemical imaging is a rapidly emerging field with new advances in instrumentation,
data acquisition and data analysis. These developments have had significant impact in …

Optical chemical imaging seeks to nondestructively acquire spatially resolved chemical

Vibrational spectroscopy and imaging promise molecular information that can be rapidly
acquired without the need for specialized stains or dyes, thereby potentially simplifying and …

Fourier-transform infrared (FT-IR) imaging is a well-established modality but requires the
acquisition of a spectrum over a large bandwidth, even in cases where only a few spectral …

The quality of images from an infrared (IR) microscope has traditionally been limited by
considerations of throughput and signal-to-noise ratio (SNR). An understanding of the …
