Analysis of closed-boundary cylindrical microlenses with long focal depth designed by the general focal length function

Point light source imaging by a three-dimensional long-imaging-depth lens

“…Some scientists have designed and analyzed the three-dimensional large-sized axilenses or axicons with LFD function by the scalar diffraction methods [1][2][3][4][5]. Other researchers have investigated the LFD cylindrical microlenses or microlens arrays based on rigorous electromagnetic theory [6][7][8][9][10][11][12][13]. All of the previous investigations are involved with the LFD properties of lenses.…”

Uniform axial intensity distributions of long-focal-depth cylindrical micromirrors realized by an amplitude-phase modulation method

“…With the development of modern fabrication technology, we can make micro optical elements whose performance analysis should be based on rigorous electromagnetic theory. In the past decade, many kinds of two-dimensional long-focal-depth (LFD) microlenses have been designed through the pure phase modulation method (PPMM) and their focal properties have been analyzed [21][22][23][24][25][26]. Rigorous numerical results demonstrated that all the designed microlenses had successfully realized the LFD functions.…”
