Reflection mode polarimetry guides laser mass spectrometry to diagnostically important regions of human breast cancer tissue

Scientific Reports
To enhance the clinical utility of mass spectrometry (MS), lengthy dwell times on less informative regions of patient specimens (e.g., adipose tissue in breast) must be minimized. Additionally, a promising variant of MS known as picosecond infrared laser

Visualisation methods for polarimetric imaging

, 2021
Polarimetric imaging is a technique for measuring the spatial correlations of the aspects of the polarisation of light. Since human vision is essentially unable to detect polarisation, the data obtained from this imaging technique must be converted into the channels of the human visual system in order to visually process the spatial correlations in the
