Mechatronic structure of modern test bench for precise angle calibration

Many optoelectronic measuring instruments, vibro-scanning devices and deflection systems have angular sensors or circular scales as a reference measure for angle determination. Most of angle measuring devices must be tested or calibrated with a relevant precision therefore a special test rig for these purposes is needed. At current technical level the precision of measurements of vibro-displacement, amplitudes or frequency of vibrations implies not only precise manufacturing and assembly but also a necessity to incorporate modern computer technologies enabling automation of the measuring process. All these components of modern technologies can be accomplished by using mechatronic constituents. This paper presents a brief review of the angle testing/calibration equipment with the integrated mechatronic devices
