Two-dimensional imaging of spontaneous ultra-weak photon emission from the human hand.
The photograph (A) taken under weak light illumination and the corresponding two-dimensional images of spontaneous ultra-weak photon emission with variable accumulation time of 10 min (B), 20 min (C) and 30 min (D). The dorsal side of the human hand was distanced at 37 cm from CCD camera window.
