The device includes an elongated sensor tube having a length, a first opening at one end of the sensor tube and a second opening at the opposite end of the sensor tube. The first opening of the sensor tube is adapted to support a video calibration sensor. A video calibration sensor is disposed in the first opening of the sensor tube. The sensor tube is sealingly secured to the image tube at an angle whereby the second opening of the sensor tube and the second opening of the image tube are substantially juxtaposed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Video calibration device","description":"A video calibration device comprising an elongated image tube having a length, a first opening at one end of the image tube and a second opening at the opposite end of the image tube.
