Claim:
1. A method for generating a 3-D image, the method comprising: producing a pattern in a spatial light modulator based on data representative of an image of an object, the data being obtained from an image that is formed by interfering (i) an intensity beam reflected from the object and obtained through an imaging pupil and (ii) a reference beam, the imaging pupil and the reference beam forming separate features in a Fourier transform of the image, said separate features comprising a central lobe and side lobes; illuminating the spatial light modulator so as to yield a projection beam; masking at least one portion of the projection beam such that a portion of the projection beam is selected; and propagating the selected portion to an exit pupil so as to form a virtual 3-D image of the object when viewed at the exit pupil.
