FIGURE 1. The multimodal endoscope concept, developed by researchers at Institut Fresnel, includes a piezo tube actuator that scans a miniature objective in a typical spiral pattern; the system based on this schematic performs multimodal imaging at high resolution, making a step toward real-time, intraoperative, label-free imaging.

FIGURE 1. STED microscopy overlaps a donut-shaped beam (for spatially selective photobleaching) with a Gaussian beam for fluorescence excitation. As the STED beam intensity is increased, it smoothly constricts the non-bleached area of the sample beyond the diffraction limit.
