Different applications of liquid crystal panels
The technology of liquid crystal panels (LCP) is very mature and can be applied in many different areas in which the modulation of an input light beam is needed. LCP can be used to modulate amplitude, phase or polarization state of the input beam, being the phase modulation the most important. For t...

The technology of liquid crystal panels (LCP) is very mature and can be applied in many different areas in which the modulation of an input light beam is needed. LCP can be used to modulate amplitude, phase or polarization state of the input beam, being the phase modulation the most important. For this reason parallel aligned LCP are the most recommended for most applications. In this paper we review a method for the characterization of these devices, especially when temporal fluctuations are present. Next we revise several applications in different fields: a) A point diffraction interferometer with phase shifting capabilities is demonstrated and applied to the recording of digital holograms that can focus, digitally, the different planes of a 3D object; b) Different techniques to obtain superresolution imaging beyond the diffraction limit of the aperture, or the geometrical limitation imposed by the pixilation of the CCD device are shown, and c) the construction of Stokes and Mueller polarimeters with different types of LCP are also shown. © 2013 SPIE. |
