UV and visible fluorescence images of maize stem: macroscopy and confocal microscopy
  • Institution/Laboratory: INRA
Fluorescence Macroscopy is a full field imaging system at low magnification. The interest is to rapidly observe large fields of view (~5x5 mm²). Fluorescence filters are used that select excitation and emission ranges of wavelengths. The spectral resolution is low. Confocal microscopy equipped with a spectral detector and several excitation lasers allows to acquire hyperspectral images. The spectral resolution is around 6-10 nm. The field of view is small and is about 500 x500 µm² with a good spatial resolution. The fusion or the multiset analysis of the two kinds of images should provide a link between the two scales of observation and therefore a strategy to develop multiscale acquisition.

SET: UV and visible fluorescence macro and microscopies.
Multi and hyperspectral UV and visible fluorescence images were acquired using a macroscope
and a spectral confocal microscope (INRA Pays de Loire).
For both devices, images were full field images. The multispectral image is built from 12 channels
and the spatial resolution is 2.7 m. The confocal hyperspectral image is built from 75 channels and
the spatial resolution is 1.25 m.
For this data set, both spatial and spectral resolution is degraded for the macroscopic images
compared to the confocal microscopy image.
The interest of the macroscope is to acquire rapidly large field of view of samples.

The two sets of images were acquired from maize stem transversal sections that are studied
within the general context of biorefinery.

One docx file is joined top the data to precisely describe the images.
