COVER FOR PASSIVE SENSOR OPERATION TEST, AND METHOD FOR TESTING PASSIVE SENSOR OPERATION USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a cover for a passive sensor operation test which can remarkably reduce a work load by making a cover part be floated using helium gas, and to provide a method for testing a passive sensor operation using the cover.;SOLUTION: A cover 1 for a passive sensor operation test comprises: a cover part 2 which is manufactured in a bowl-shaped bag body into/from which helium gas can be injected and exhausted, and suppresses the arrival of a far-infrared ray to the passive sensor with being held on a ceiling by buoyancy generated by expansion of the injected helium gas so as to cover the passive sensor; and a string 4 of which one end is connected to the cover part 2 and which moves the cover part having the buoyancy generated by pulling the other end side.;COPYRIGHT: (C)2012,JPO&INPIT
