Abstract

With the development of more powerful lasers for applications, optical limiters and blockers are required for providing human eye and optical sensors protection. In some scenarios, laser radiation may seriously interrupt the signal, from transient saturation and can lead to permanent damage. We present a variety of non-linear, solid-state dynamic filter solutions protecting from dazzling and damage in a passive way. Our filters either limit or block the transmission, only if the power exceeds a certain threshold as opposed to spectral filters that block a certain wavelength permanently. We propose a dynamic protection for cameras, sensors and the human eye from laser threats.
