| 1. A method for imaging an object, comprising:
providing an imaging device having a prism;
determining a wavelength range of light, over which an index of refraction of the prism remains substantially constant;
transmitting non-monochromatic light in the determined wavelength range through an optical transmitter to the prism;
passing the light in the determined wavelength range through the prism, so that an index of refraction of the prism remains
substantially constant over the determined wavelength range;
applying an electromagnetic field to the prism, the prism having the index of refraction that varies with changes in the applied
electromagnetic field, such that the light exiting from the prism deflects at a substantially controlled angle; and
directing the light exiting the prism towards the object for imaging.
