Optical limiting effect
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. WebDistinctly different from conventional optical limiters, the nanoscale MQW thin film for a femtosecond pulse limiter works in the reflec-tion mode schematically shown in Fig. 3A. As a consequence, it can be integrated onto the surface of an existing optical component down to subwavelength scale, significantly simplifying the optical limiting
