Abstract: This paper presents RecNet, an innovative convolutional neural network designed for reconstructing cecond harmonic generation frequency-resolved optical gating (SHG-FROG) traces. Unlike conventional approaches, RecNet incorporates noiseless sample constraints through a domain knowledge embedded loss function,… read more here.
