Dear Editor,We have read with interest the commentary by McAvoy and Tudor-Locke on our article entitled "Association of accelerometer-derived step volume and intensity with ho spitalizations and mortality in older adults:A prospective cohort study". The authors expressed some concerns about our methodology used to define accelerometer-derived step intensity and the analytical approach applied in our study.

We present,to the best of our knowledge,the first implementation of full-field quantum optical coherence tomography(FF-QOCT).In our system,we are able to obtain full three-dimensional(3D)information about the internal structure of a sample under study by relying on transversely resolved Hong–Ou–Mandel(HOM)interferometry with the help of an intensified CCD(ICCD)*** system requires a single axial scan,obtaining full-field transverse single-photon intensity in coincidence with the detection of the sibling photon for each value of the signal-idler temporal *** believe that this capability constitutes a significant step forward toward the implementation of QOCT as a practical biomedical imaging technique.
