The company needed someone to monitor a new kind of technology called side-scan sonar, which uses ultrasonic sound waves to create images of items on an ocean or lake bottom. "I volunteered," he said.
Side-scan uses a sonar device that emits conical or fan-shaped pulses down toward the seafloor across a wide angle perpendicular to the path of the sensor through the water, which may be towed from a surface vessel or submarine (called a “towfish”), or mounted on the ship's hull.
For photo scanning, it doesn't get better than this $200 scanner from Amazon. You can scan stacks of photos at a time without having to manually open a scanner or align pictures perfectly.
Side scan sonar technology Martin Klein (born April 5, 1941) is an American engineer and inventor. He worked in the development of the side scan sonar, a tool used in maritime archaeology, deep-sea and coastal survey, marine geology, offshore engineering and military mine defense.
Further developments in the field remained sparse until the 1970s, when military applications began driving research. Commercial applications followed and the first affordable consumer equipment was sold in 1975. [4] In 1972, the Apollo 17 mission carried a ground penetrating radar called ALSE (Apollo Lunar Sounder Experiment) in orbit around ...
A common use of ultrasound is in underwater range finding; this use is also called sonar. An ultrasonic pulse is generated in a particular direction. If there is an object in the path of this pulse, part or all of the pulse will be reflected back to the transmitter as an echo and can be detected through the receiver path. By measuring the ...
Multibeam sonar is used to map the ocean floor. A multibeam echosounder (MBES) is a type of sonar that is used to map the seabed. It emits acoustic waves in a fan shape beneath its transceiver. The time it takes for the sound waves to reflect off the seabed and return to the receiver is used to calculate the water depth.
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
