New scattering compensation method is compatible with widefield #Fluorescence #Microscopy, requiring tens of frames of raw data acquired using random illumination patterns, but without the need for a spatial light modulator or target sparsity: https://t.co/wuNtNVY9xs

Leveraging this analogy, we show Ptychographic imaging of reflective targets using a commercial MCF and simple intensity-only camera-based detection. Interested? Check out the full paper here: https://t.co/y0T3gws4gZ 3/3

However, coherent imaging with these fibers requires correcting core-to-core phase distortions. We show that conventional raster scanning in confocal endoscopy with multicore fibers (MCFs) is analogous to probe scanning in ptychography. 2/3

We repeat this and scan the ultrasound focus over several areas of the object, resulting in a field of view much larger than the 'memory effect'

Our paper presents a method that combines minimally scattering acoustic waves and high-resolution optical waves. By targeting 'memory-effect' regions with acoustic focus, we demonstrate matrix-based scattering compensation that relies on detecting the tagged optical fields.

Imaging through scattering media at optical resolution is crucial for applications like deep tissue imaging in biomedicine. Current techniques highly depend on the optical 'memory effect', which significantly limits their field of view.

Advertising for the #Amazing "Image Science" @GordonConf to take place in June in Maine. Official deadline is in May, but better to apply ASAP to secure a seat. We are currently gathering significant sponsors to support Junior Researchers. https://t.co/SHqziTLlRl
