An improved scan mode in an electrostatic force microscope for surface profile measurement of micro-optics

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2014
A new scan mode referred to as the feed-forward controlled unidirectional scan mode is employed to improve the accuracy of surface profile measurement of micro-optics in a scanning electrostatic force microscope (SEFM) instead of the conventional ...

Directional thermal emission and display using pixelated non-imaging micro-optics

Nature Communications
Thermal radiation is intrinsically broadband, incoherent and non-directional. The ability to beam thermal energy preferentially in one direction is not only of fundamental importance, but it will enable high radiative efficiency critical for many thermal

Characterization of image transfer through grin media using mtf [PDF]

, 2013
Una lente común homogénea posee dos características físicas que influyen en la manera en que dicha lente reconfigura un frente de ondas: la diferencia entre su índice de refracción y el del medio circundante, y la curvatura de sus interfaces. Sin embargo,
