Quantitative evaluation of LED based optical autofocus module

Quantitative evaluation of LED based optical autofocus module This dataset is used to quantify the performance of an autofocus system, openAF with LED /SLD, using a 2D astigmatic autocorrelation defocus model. There are two folders for each autofocus light source: LED without background subtraction LED with background subtraction SLD without background subtraction SLD with background subtraction Each folder contains the experimental dataset: a reference bead z-stack, time-lapse of the astigmatic 100 nm fluorescent beads obtained during the operation of the openAF autofocus and the autofocus metadata. Additionally, the pre-computed values of astigmatic defocus using autocorrelation model as presented in the paper are included. "Range_exp" folder contains the experimental data for evaluation the optical range of the LED openAF.
