Design and experimental test of diffractive superresolution elements

Abstract

By using previously established methods based on linear programming (MLP), we design and fabricate two types of diffractive superresolution element (DSE). The structure parameters and superresolution performances of the fabricated DSEs are tested. The test results agree well with the design results and are applicable to a writable or a read-only optical disk. Thus the application validity of the MLP is experimentally verified.

Methanol activation catalyzed by Pt7, Pt3Cu4, and Cu7 clusters: A density functional theory investigation

“…[2,3] In this regard, direct methanol fuel cell (DMFC) [4,5] is a good solution. First, methanol as a liquid fuel [6] is easy to be stored and transported like gasoline and diesel. Second, methanol can be easily synthesized from other feedstocks.…”

Superresolved femtosecond laser nanosurgery of cells

“…These phase-only filters can be implemented dynamically in optical instruments by use of a phase-controlling device such as a deformable mirror or a Spatial Light Modulator (SLM). In addition, it is possible to produce these phase masks as static phase filters in glass [15, 19]. …”

Superresolved femtosecond laser nanosurgery of cells

“…In the first approaches, these filters were realized by obstruction of light in concentric annular zones [13]. Later, attention was shifted to the design of phase-only pupil filters [16][17][18][19][20] due to their better transmittance. These phase filters have been based on two or more annular zones with a mutual phase difference of π radians.…”
