DEVICE MEASURING TRANSLATION, VELOCITY, ACCELERATION AND RATE OF MOTION OF OBJECT Russian patent published in 2004 - IPC

FIELD: equipment for contactless measurement of parameters of reversible motion of object. SUBSTANCE: device incorporates light source, flag coupled to mobile object, photorule ( for example, linear charge-coupled device ), electron unit and computer making it feasible to record position of middle of flag shadow on photorule while it moves with high frequency. Electron unit includes video amplifier, comparator and microcontroller. Input of photorule is connected to clock pulse output of microcontroller, output of photorule is connected to input of video amplifier, output of video amplifier is coupled to first input of comparator, second input of comparator is connected to threshold setting output of microcontroller, forward and inverting outputs of comparator are connected to inputs of microcontroller and output of microcontroller is coupled to input of computer. EFFECT: increased measurement accuracy of dependence of velocity on translation thanks to elimination of mechanical link between object and sensitive element. 1 dwg
