Download scientific diagram | A MDOE that acts as a Fresnel lens with a refractive power that depends on their mutual rotation angle. Gray values in the figure actually correspond to phase-shift values between 0 and 2π. Note that the two DOEs are identical if one of them is reversed (i.e., flipped upside down). from publication: Adjustable refractive power from diffractive moire elements | We show how suitable combinations of cascaded diffractive optical elements (DOEs) can form a combined "moiré DOE" of adjustable refractive power and high diffraction efficiency. The optical power can be adjusted continuously by a mutual rotation of one DOE with respect to the | Refractometry, Equipment Failure Analysis and Radiation Scattering | ResearchGate, the professional network for scientists.
