Abstract:In order to satisfy the remote detection requirements for the surface defects on the cables of cable stayed bridges, an opto-mechanical system of a high definition video telephoto objective is designed and manufactured. According to the objective definition requirement of 4 mm at the distance of 300 m, the imaging definition of 234 cycle/mm with a focal length of 320 mm is determined. A proper initial configuration is chosen, and then some optimization procedures are carried out with the optics design program … Show more
