摘要:
A laser sensor module array for vehicle identification, speed monitoring and traffic safety applications. Each of the laser sensor modules comprise a laser signal transmitting and receiving port with the array comprising a basic row of N laser sensor modules, wherein N is greater than 1 and wherein each of the N laser sensor modules in the basic row is displaced at an acute angle with respect to adjacent ones of the laser sensor modules. An additional row of N laser sensor modules may adjoin the basic row of N laser sensor modules in a parallel or acute angular relationship to corresponding ones in the basic row.

摘要:
An improved and simplified laser safety screen and method utilizing a novel rotating mirrored polygon hub having mirrored surfaces with at least one of the surfaces in an orientation (or angle θ) other than parallel to the axis of rotation of the hub. In other words, the angle θ for each side of the polygon may be made independent for each phase and, in certain instances, a given phase can also be zero
