Abstract
Adverse environmental effects may be canceled from an optical processor which adjusts the phase of spatially distributed frequency components. This is achieved by projecting the optical modulated signal and a local oscillator optical signal along the same optical path and through the same optical components. Multichannel operation is achieved by positioning the optical components for each stage along a common axis.
