摘要: An image acquisition system is operated to provide an that relatively free of the effect longitudinal chromatic aberration. The includes a variable focal length lens (e.g., tunable acoustic gradient index refraction lens) periodically modulate focus position. First, second, third, etc., wavelength exposure contributions are provided by operating illumination instances strobed first, wavelengths green, blue, red, etc.) timed correspond with respective phase timings modulated position which at same plane. compensate for aberration least lens. produced combining contributions.
