WebJul 4, 2014 · An important term in the optical limiting study is the optical limiting threshold. Optical limiters are essentially those systems which transmit light at low input fluence or intensities but become opaque at high inputs. The optical limiting property is mainly found to be absorptive nonlinearity, which corresponds to the imaginary part of third ... WebThe influences of concentration, thickness, and solvent on the nonlinear optical limiting effect of the graphene dispersion are analyzed. The experimental results show that the …

WebDec 26, 2016 · The optical limiting properties are measured by a transmission technique. We find that the limiting threshold can be improved by a proper choice of glucose concentration in sample solution. A 3,4-pyridinediamine with 80 mmol glucose concentration showed a good switching property. WebApr 12, 2024 · Noninvasive imaging through scattering media using memory effect (ME) normally suffers from the failure of imaging when the object is beyond the ME region, limiting its field of view (FOV). Herein, a method to enlarge the FOV is proposed by utilizing point-spread-function (PSF) estimations and correlations. WebJan 17, 2024 · Based on the strong ESA caused by CSSs absorption, the MOF nanosheets showed an excellent optical limiting (OL) effect with the OL threshold of 0.89 J/cm ² .
