Light Aberration Effect in HR Geometric Model
Light Aberration Modelling Geometric Accuracy Pleiades
2015/11/23
The advent of commercial observation satellites with an increasingly fine resolution requires the definition of whenever more accurate geometrical models to correct most of the main image distortions....
Calibration of fisheye camera systems and the reduction of chromatic aberration
Camera calibration fisheye panorama chromatic aberration mobile mapping omni-directional imaging
2015/8/25
This paper reports on the camera calibration procedure developed at CycloMedia and its modification for the reduction of chromatic aberration for further improvement of CycloMedia’s main product: 360o...
Modelling of chromatic aberration for high precision photogrammetry
RGB colour calibration chromatic aberration precision accuracy
2015/8/24
Chromatic aberration appears for almost all lenses for imaging based on white light. The effect degrades image quality for both b/w and colour cameras. This paper discusses the possibilities of modell...
Spherical Aberration Correction Using Refractive-Diffractive Lenses with an Analytic-Numerical Method
spherical aberration flat or curved phase coefficients
2010/2/19
We propose an alternative method to design diffractive lenses free of spherical aberration for monochromatic light. Our method allows us to design diffractive lenses with the diffraction structure rec...
Present status and future prospects of spherical aberration corrected TEM/STEM for study of nanomaterials
spherical aberration correction TEM/STEM nanomaterials electron diffraction three-dimensional observation

The present status of Cs-corrected TEM/STEM is described from the viewpoint of the
observation of nanomaterials. Characteristic features in TEM and STEM are explained using
the experimental data obt...
We introduce the novel parallel-aligned liquid crystal wavefront corrector (LC WFC) with 1920*480 pixels designed to operate at phase-only mode. The optical characteristics of the LC WFC were measured...
