WebApr 5, 2024 · require short gate times. In practice, most systems that make use of time gating to reject scattered light depend on the use of the optical Kerr gate (OKG) technique [10–13]. Imaging of a target in a highly scattering medium using an OKG could enhance the imaging quality. Recently, the OKG technique WebOct 1, 2014 · We demonstrated the time-gated ballistic imaging technique using a femtosecond optical Kerr gate (OKG) of bismuth–plumbum oxide glass, the nonlinear optical properties of which were also...

WebPhoto Eyes or Beams are “non-contact” devices that operate by shooting a beam of light across the gate opening. When wired up as an entrapment device interrupting the beam … WebThe ultra-fast switching properties of the Kerr-gate can be used for optical imaging in medicine (see [2] and the references therein). Light reflected from the tissue (a strongly scattering medium) is then passed through a Kerr shutter in which (nonlinear) birefringence is induced by short infrared pulses.

WebNov 22, 1991 · A technique called optical coherence tomography (OCT) has been developed for noninvasive cross-sectional imaging in biological systems. OCT uses low-coherence interferometry to produce a two-dimensional image of optical scattering from internal tissue microstructures in a way that is analogous to ultrasonic pulse-echo imaging. WebApr 26, 2024 · In this study, we have designed and simulated a photonic crystal (PhC) nonlinear AND logic gate. First, a suitable photonic crystal ring resonator (PhCRR) structure is designed and simulated that can be used for obtaining the switching power intensity after applying the nonlinear Kerr effect. In this structure, GaAs dielectric rods have been used in …
WebMar 21, 2012 · For optical Kerr gate measurements the two-beam setup is slightly modified. The energy in one of the paths is reduced to ∼6 μJ so that this beam path acts as a probe beam and the other beam path acts as a pump beam. In the probe beam path a λ /2 plate is placed before the sample and an analyzer is located after the sample (Fig. 1 (d)).
