Remote sensing using passive solar illumination in the Short-Wave Infrared spectrum is exposed to strong intensity variation in the spectral bands due to atmospheric changing conditions and spectral absorption. More robust spectral analysis methods,... Read More about Spectral index selection method for remote moisture sensing under challenging illumination conditions.

Freeform based hYperspectral imager for MOisture Sensing (FYMOS) (2021)
Journal Article

Comparison of closed loop and sensorless adaptive optics in widefield optical microscopy (2013)
Journal Article
Bourgenot, C., Saunter, C., Love, G., & Girkin, J. (2013). Comparison of closed loop and sensorless adaptive optics in widefield optical microscopy. Journal of the European Optical Society-Rapid Publications, 8, Article 13027. https://doi.org/10.2971/jeos.2013.13027

We report on a closed loop widefield adaptive optics, optical microscopy system in which the feedback signal is provided by backscattered light from the sample acting as a guide star. The improvement in imaging performance is compared to an adaptive... Read More about Comparison of closed loop and sensorless adaptive optics in widefield optical microscopy.

3D adaptive optics in a light sheet microscope (2012)
Journal Article
