Different aberrometry methods exist and the magnitude of measured wavefront aberrations may differ depending on the method used. Even several Shack-Hartmann wavefront sensors may demonstrate clinically significant differences between ocular aberrations measured. In this study, we tested a hypothesis that a possible source of systematic error in Shack-Hartmann aberrometry may be the presence of spherical...
In this paper, the gamma - gamma probability distribution is used to model turbulent channels. The bit error rate (BER) performance of free space optical (FSO) communication systems employing on-off keying (OOK) or subcarrier binary phase-shift keying (BPSK) modulation format is derived. A tip-tilt adaptive optics system is also incorporated with a FSO system using the above modulation formats. The...
The objective of the project "visual attention module for autonomous mobile robots" is the development of an artificial visual system for mobile robotics applications, which provide the representation of the dynamic environment of a mobile robot, applying an attention-based scene analysis. The architecture of the system is biologically motivated, its vision-based environment and object representation...
