1. A method of imaging an object, the method comprising:
providing an optical imaging system comprising
an optical assembly comprising one or more adaptive multielectrode electrowetting optical elements, each of the adaptive multielectrode electrowetting optical elements having at least at least three degrees of freedom; and
a photodetector disposed so as to detect transmitted radiation from the object, the optical assembly being disposed in a beam path between the photodetector and the object, and
receiving transmitted radiation from the object at the photodetector to provide a base image; and
performing the following steps one or more times:
adjusting the one or more adaptive multielectrode electrowetting optical elements, the adjustment including modifying an optical transfer function of the one or more adaptive multielectrode electrowetting optical elements, and
receiving transmitted radiation from the object at the photodetector to provide an adjusted image;
wherein the adjustment and receiving steps are performed until the adjusted image has substantially reduced aberrations compared to the base image.
