Advances in computer technology have dramatically increased raytrace speeds in optical engineering software. Increases in raytrace speed have, in turn, led to new methods for evaluating optical system performance. Designers traditionally evaluate imaging system performance with spot diagrams, MTF plots, ray aberration plots, and distortion plots. These tools are invaluable for two reasons: 1) t...

Optimization capability is perhaps the most important feature of modern optical design software. Given a starting system, the software changes automatically the system parameters in order to make the system as good as possible, in a sense that will be made more precise below. The purpose of optical system design is to produce for an optical system a prescription (i.e., a list of all system para...

Inside armored personnel carriers, APC’s, such as e.g. Hägglunds CV90 or Mowag Piranha, the possibilities for looking out are rather limited. That is especially true for the soldiers being transported inside the personnel compartment. Because of this, the soldiers are in effect expected to put themselves into harms way with very limited knowledge of what is happening outside the vehicle. One po...

the aim of this research was to construct an equipped hive with the acquisition, communication and analysis systems to send images on-line, wirelessly. this system could be used to evaluate density of bee colonies and also work as bait box to eliminate bee pest, if necessary. in this study, two methods, optical flow and neighborhood gray-tone difference matrix, were used to determine hive condi...

  A radioactive ion beam of 6He produced via the 7Li(p,2p)6He reaction with typical intensity of 3 × 106 ions/see was elastically scattered from LiF(Au) targets. Elastic scattering of 6He at Elab=27 MeV with 197Au have been measured in the angular range of 6º-72º in the laboratory system employing LEDA and LAMP detection system. Optical Model calculations have been used to fit the data .
