In our paper [1], reconstructions have been carried out for simulated single and dual fluorescence targets. However, we have recently discovered that the volume size 0.01 0.01 0.01×0.01cm×cm proposed was a writing mistake.

Therefore, on page 9727, line 6 should be read as “The size of the cubic fluorescent target was 0.1×0.1×0.1cm” and at line 10 for dual targets, “Two small cubic targets with volume size 0.1×0.1×0.1cm were placed at an edge to edge distance varying from 0.3cm to 0.1cm.”
