High-resolution scanning fluorescence imaging through scattering via speckle replica alignment and variance computation
Lei Zhu, Tengfei Wu, Bernhard Rauer +2
Fluorescence imaging is an essential diagnostic tool in many fields, but diffraction-limited optical imaging at depth is limited by scattering. Here, we present a method based on m…
Light and Sound Driven Wavefront Shaping and Imaging through Scattering Tissue
Fei Xia, Ivo Leite, Shuquan Xiao +4
Deep, high-resolution imaging is essential for unraveling biological complexity and advancing medical diagnostics, yet scattering fundamentally limits optical methods. Among the mo…
Optical kernel machine with programmable nonlinearity
SeungYun Han, Fei Xia, Sylvain Gigan +2
Optical kernel machines offer high throughput and low latency. A nonlinear optical kernel can handle complex nonlinear data, but power consumption is typically high with the conven…
Nonlinear optical encoding enabled by recurrent linear scattering
Fei Xia, Kyungduk Kim, Yaniv Eliezer +4
Optical information processing and computing can potentially offer enhanced performance, scalability and energy efficiency. However, achieving nonlinearity-a critical component of…
Correlating light fields through disordered media across multiple degrees of freedom
Louisiane Devaud, Bernhard Rauer, Simon Mauras +2
Speckle patterns are inherent features of coherent light propagation through complex media. As a result of interference, they are sensitive to multiple experimental parameters such…
