A method for imaging an object is disclosed. The method may include transmitting
light in a predetermined wavelength range through an optical transmitter to a prism,
applying an electromagnetic field to the prism, and passing said light through
the prism. The prism may be configured to have an index of refraction that varies
with changes in the applied electromagnetic field and that remains substantially
constant with changes in wavelength of light over the predetermined wavelength
range such that said light exiting from said prism deflects at a substantially
controlled angle.
