Spatially-resolved measurement of optically stimulated luminescence and time-resolved luminescence [PDF]

open access: yesRadiation Measurements, 2003
Spatially-resolved measurements of optically stimulated luminescence (OSL) were performed using a two-dimensional scanning system designed for use with planar samples. The scanning system employs a focused laser beam to stimulate a selected area of the sample, which is moved under the beam by a motorised stage.

Image-Processing Software for High-Throughput Quantification of Colony Luminescence

open access: yesmSphere, 2019
Many microbiological assays include colonies that produce a luminescent or fluorescent (here generalized as “luminescent”) signal, often in the form of luminescent halos around the colonies.
