Two applications of liquid crystal displays in diffractive optics under polychromatic illumination

The amplitude and phase modulations provided by a liquid-crystal spatial light modulator (LCSLM) depend strongly on the wavelength used for illumination. This is the main reason why usually LCSLMs are only applied with monochromatic illumination. However, there are a number of potential applications...

description The amplitude and phase modulations provided by a liquid-crystal spatial light modulator (LCSLM) depend strongly on the wavelength used for illumination. This is the main reason why usually LCSLMs are only applied with monochromatic illumination. However, there are a number of potential applications where it would be very interesting to combine the programmability provided by LCSLMs and the use of non-monochromatic illumination. In this work we focus on two such applications. On one hand, we use an axial apodizing filter to compensate the longitudinal secondary axial color (LSAC) effects of a commercial refractive optical system on the polychromatic point-spread function (PSF). The configuration of the LCSLM has been optimized to obtain the amplitude-mostly regime in polychromatic light. On the other hand, we show a programmable diffractive lens which is able to provide equal focal length for several wavelengths simultaneously. To achieve this achromatization it is necessary that the LCD operates in the phase-only regime simultaneously for the different wavelengths.
