Two-dimensional imaging of spontaneous ultra-weak photon emission from the human hand using software and hardware binning.
(A), Two-dimensional imaging of ultra-weak photon emission measured with software binning mode and variable accumulation time. (B), Two-dimensional imaging of ultra-weak photon emission measured with hardware binning mode and variable accumulation time. Accumulation times ranging from 10 min to 30 min were analyzed as shown in the x-axis and binning factor applied is shown in the y-axis. The binning factor ranges from 1 × 1 to 4 × 4.
