Optics: fast and furious imaging With optics coming of age and its widespread use in biomedical sciences, scientists invest substantial efforts in new imaging technologies. The aim is to reconcile versatility, performance and cost issues. Developments take place in the design of new molecules with expanded capabilities (e.g., increased resistance to photodamage, exquisite sensitivity to excitation frequency, chemical stability). But they also pursue the engineering of more flexible sensors and stimulators with improved performance (e.g. higher quantum efficiency detectors, higher signal-to-noise ratios and the choice of selectable wavelengths of excitation with narrower bandwidths). Being able to quickly switch across different stimulation wavelengths while keeping them as narrow as possible is of great value for the experimenter. The optical properties of most materials largely depend...
