High Resolution Optical Imaging Deep in Living Tissue
Breakthroughs in imaging technology have been the primary driving force of new biological discoveries. However, up to now, high-resolution optical imaging deep in tissues was challenging because of optical aberrations and scattering of light caused by the complex structure of living matter.
Here, researchers from the the Hong Kong University of Science and Technology present an adaptive optics three-photon (3P) microscope, based on analog lock-in phase detection for focus sensing and shaping (ALPHA-FSS), to accurately measure and compensate for both aberrations and scattering induced by specimens and to recover subcellular resolution at depth. The microscope employed ORPHEUS-F short-pulse excitation at 1300 nm, enabling imaging up to 1.1 mm below the pia within the intact brain.
