Fig. 8: Accounting for intensity pedestal and calculating noise from the experimental data.

From: Fast mode decomposition in few-mode fibers

Fig. 8

Figure shows a measured intensity profile, b pedestal intensity distribution, and c histogram of the pedestal. Mean decomposition time is 63 µs for 128 × 128 images. The measured SNR value is 23 dB.
