WebA wavefront is optimized imaging a sample. A binary off-axis hologram is encoded by selective adoption of states for each mirror of a deformable mirror device, which is illuminated with an incident beam of light. A single diffraction order that has encoded phase-mask information is selected from light reflected from the deformable mirror device and … WebDifferent quantitative definitions are used in the literature: According to the most common definition, the beam divergence is the derivative of the beam radius with respect to the axial position in the far field, i.e., at a distance from the beam waist which is much larger than the Rayleigh length.This definition yields a divergence half-angle (in units of radians), and …
WebThe simplest form of a wavefront is the plane wave, where the rays are parallel to one another. The light from this type of wave is referred to as collimated light.
