Abstract/Summary

The Ultrasonic Camera imaging system that has been developed is a prototype system, capable of producing an image of solid objects, using the concept of Ultrasonics. The system hardware includes a transmitter, which releases a short ultrasonic pulse, and a receiver, which waits for the return echo. A filter on the receiver side has been employed to remove any unwanted signal. The time from transmission until the receipt of the first echo of the pulse is measured. This represents the distance of the object from the system. The measured time-of-flight is converted into range units. After all the range information of a scene has been collected, the system software will construct and display the image on a microcomputer monitor. The image on-screen shows only the silhoutte of the target object with respect to the system transducer. Sixteen colors, ranging from black to white, are used to represent the distance of the object from the transducer. Dark colors mean that an object is quite near the system as the distance increases, the colors become lighter.
