Reflection matrix microscopy at 1.6 µm wavelength for label-free deep-tissue imaging
Multiple light scattering sets the depth limit of optical microscopy in biological tissue. Reflection matrix microscopy with the multiple-scattering tracing algorithm can overcome this scattering, but its application has so far been limited to wavelengths of 1.3 μm and below. Here, we develop, to our knowledge, the fir...
