Paper Abstract

The results of a computer model of the far field diffraction pattern of the Texas Instruments cantilever beam inverted cloverleaf deformable mirror device (DMD) are presented. Both amplitude and phase in the Fourier transform plane are studied using a variety of input DMD phase objects. Changes in the Fourier plane phase and amplitude produced by changes at the input (including random leaflet-to-leaflet input phase errors) are investigated. The phase in the Fourier plane was found to be very sensitive to even slight variations in the deflections of the individual mirror leaflets. This could limit its usefulness as an input device.
