Abstract: A method for examining a specimen via light sheet microscopy includes selecting several illumination wavelengths for the specimen. To structure the illumination light, a predefined phase distribution is impressed on the phase-selective element and a predefined aperture structure is impressed on an aperture in the aperture plane.

The specimen is illuminated with the structured light sheet in the light sheet plane. Light emitted by the specimen is detected in a detection direction which forms an angle different from zero with the light sheet plane.

Abstract: A fiber scanning system can have optimized performance by substantially matching the natural frequencies of the fiber scanning system's actuator and fiber optic scanning element. By matching the natural frequencies, the fiber scanning system can increase the maximum distance that the tip of the fiber optic scanning element may be driven relative to a resting position. Such an effect may be produced because matching the natural frequencies of the fiber scanner allows for larger amplitudes to be achieved. It should be noted that the natural frequency of the scanning system can be selected to avoid excitation frequencies that could destabilize the system. In this way, the system as a whole may act as a tuned mass damper or a tuned resonance structure, thereby improving scan performance while maintaining a stable scanning system.
