  • Motion state of impacting and impacted object measuring apparatus and method
    Patent number: 8959981
    Abstract: A measurement apparatus includes a first Doppler sensor which outputs a first transmission signal and receives a first Doppler signal, that is the first transmission signal returned after being reflected by an impacting object, a timing detection unit that detects an impact timing which is a moment when an impacted object is impacted by the impacting object, an impacting object speed computing unit that computes a speed of the impacting object based on the first Doppler signals obtained from the detected impact timing to a timing before a predetermined period, and an imaging unit that images the impacted object immediately after the impact so as to be used for computing a motion state of the impacted object, based on the computed speed of the impacting object.
