the present study aims to have a comparative study of the results, from biological monitoring as well as conventional method, based on physico-chemical variables. water quality index (wqi) and planktonic diatom metrics have been used to determine water quality and ecological conditions of the dong nai river (dnr) and canonical correspondence analysis (cca) to find out the main environmental var...
We report experimental evidence and correction of defocus in full-field optical coherence tomography of biological samples owing to mismatch of the refractive index of biological tissues and water. Via a metric based on the image quality, we demonstrate that we are able to compensate this index-induced defocus and to recover a sharp image in depth.
