A systematic and quantitative analysis is given of the impact pupil aberrations on imaging performance in wavefront manipulation applications using adaptive optical elements. For practical case rotationally-symmetric types corrections, such as defocus or spherical aberration, analytical expressions induced are derived including their field dependence. Each aberration thereby related to specific...

The observability of radome aberration estimation with line-of-sight (LOS) angle-only measurement is studied in this paper. When missile seeker can only measure LOS angle of target, target state variables are required to be estimated with this measurement for accurate missile guidance. Since LOS angle measurement contains error, caused by radome attached at missile nose and called radome aberra...

For more than two decades, chromosome aberration analysis has been used in biomonitoring of occupational and environmental exposure to ionising radiation. Chromosome aberration analysis is a method used to detect unstable aberrations in the lymphocytes of irradiated personnel. In turn, stable chromosome aberrations that arise some time after exposure are detected using the multicolour fluoresce...

Measurement of the eye's wave aberrations has become fairly standard in recent years. However, most studies have not taken into account the possible influence of the polarization state of light on the wave aberration measurements. The birefringence properties of the eye's optical components, in particular corneal birefringence, can be expected to have an effect on the wave aberration estimates ...

introduction: robertsonian translocation is one of the major chromosomal rearrangements with a prevalence rate of 0.1% of the general population and 1% of the infertile population. in this report, we present a nonhomologous robertsonian translocation in a female patient with a history of repeated abortions. case presentation: a couple with the complaint of repeated abortions was admitted in the...

background: ct scan and nuclear medicine exams deliver a great part of medical exposures. this study examined professional radiation hazards in ct scan and nuclear medicine workers.   methods : in a cross sectional study 30 occupationally exposed workers and 7 controls (all from personnel of a laboratory) were selected. physical dosimetry was performed for exposed workers. blood samples were ob...

Recent developments in aberration control in the TEM have yielded a tremendous enhancement of direct imaging capabilities for studying atomic structures. However, aberration correction also has substantial benefits for achieving ultra-resolution in the TEM through reciprocal space techniques. Several tools are available that allow very accurate detection of the electron distribution in surfaces...
