when was the first fiber optic endoscope introduced
Endoscopy Basil Hirschowitz and Larry Curtiss invented the first fiber optic endoscope in 1957.[20] Earlier in the 1950s Harold Hopkins had designed a "fibroscope" consisting of a bundle of flexible glass fibres able to coherently transmit an image. This proved useful both medically and industrially, and subsequent research led to further improvements in image quality. Further innovations included using additional fibres to channel light to the objective end from a powerful external source, thereby achieving the high level of full spectrum illumination that was needed for detailed viewing, and colour photography.[citation needed]
Philo Farnsworth Philo Taylor Farnsworth (August 19, 1906 â€“ March 11, 1971) was an American inventor and television pioneer.[2] He made many contributions that were crucial to the early development of all-electronic television.[3] He is perhaps best known for his 1927 invention of the first fully functional all-electronic image pickup device (video camera tube), the "image dissector", as well as the first fully functional and complete all-electronic television system. He was also the first person to demonstrate such a system to the public.[4][5] Farnsworth developed a television system complete with receiver and camera, which he produced commercially in the form of the Farnsworth Television and Radio Corporation, from 1938 to 1951, in Fort Wayne, Indiana.[6][7]
