Noise reduction in resonator-based ultrasound sensors by using a CW laser and phase detection
(Optical Society of America, 2019-06)
The detection of ultrasound via optical resonators is conventionally performed by tuning a continuous-wave (CW) laser to the linear slope of the resonance and monitoring the intensity modulation at the resonator output. ...
Innovative speckle noise reduction procedure in optical encryption
(Institute of Physics Publishing, 2017-05)
Encrypting techniques are currently of interest in the optical domain. A common issue when using coherent techniques is speckle noise which influences the final results. Most efforts to solve this issue were directed towards ...
Impact of view reduction in CT on radiation dose for patients
(Elsevier, 2017)
Iterative methods have become a hot topic of research in computed tomography (CT) imaging because of their capacity to resolve the reconstruction problem from a limited number of projections. This allows the reduction of ...

Noise Exposure Potentiates Exocytosis From Cochlear Inner Hair Cells
(Frontiers Media, 2021-09-29)
Noise-induced hearing loss has gained relevance as one of the most common forms of hearing impairment. The anatomical correlates of hearing loss, principally cell damage and/or death, are relatively well-understood ...
Experimental optical encryption of grayscale information
(OSA - The Optical Society, 2017-07)
In this paper, we present a new protocol for achieving lower noise and consequently a higher dynamic range in optical encryption. This protocol allows for the securing and optimal recovery of any arbitrary grayscale images ...
