Title:
ULTRASONIC DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/047204
Kind Code:
A1
Abstract:
Provided is an ultrasonic detection device that, if detection results of a reflection-type ultrasonic sensor are results detected in a state with no adhered matter on an ultrasound transmission surface, is capable of guaranteeing that this is the case. An ultrasonic detection device (1) according to the present invention is provided with a reflection-type ultrasonic sensor (11) having a transmission unit for transmitting ultrasound and a first reception unit for receiving the ultrasound and an ultrasonic sensor for diagnosis (13) near the ultrasound transmission surface of the transmission unit. The ultrasonic sensor for diagnosis (13) has a second reception unit for receiving ultrasound transmitted from the ultrasound transmission surface and detects the presence of adhered matter D adhered to the ultrasound transmission surface on the basis of the reception results of the second reception unit.
