    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.
