Microparticle manipulation and imaging through a self-calibrated liquid crystal on silicon display

We present in this paper a revision of three different methods we conceived in the framework of liquid crystal on silicon (LCoS) display optimization and application.We preliminarily demonstrate an LCoS self-calibration technique, from which we can perform a complete LCoS characterization.

In particular, two important characteristics of LCoS displays are retrieved by using self-addressed digital holograms. On the one hand, we determine its phase-voltage curve by using the interference pattern generated by a digital two-sectorial split-lens configuration. On the other hand, the LCoS surface profile is also determined by using a self-addressed dynamicmicro-lens array pattern. Second, the implementation of microparticle manipulation through optical traps created by an LCoS display is demonstrated. Finally, an LCoS display based inline (IL) holographic imaging system is described. By using the LCoS display to implement a double-sideband filter configuration, this inline architecture demonstrates the advantage of obtaining dynamic holographic imaging of microparticles independently of their spatial positions by avoiding the non-desired conjugate images. © 2018 by the authors. 2018 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_20763417_v8_n11_p_Zhang http://hdl.handle.net/20.500.12110/paper_20763417_v8_n11_p_Zhang
