Applying Speckle Noise Suppression to Refractive Indices Change Detection in Porous Silicon Microarrays

open access: yesSensors, 2019
The gray value method can be used to detect gray value changes of each unit almost parallel to the surface image of PSi (porous silicon) microarrays and indirectly measure the refractive index changes of each unit.
