In later life, Farnsworth invented a small nuclear fusion device, the Farnsworth–Hirsch fusor, employing inertial electrostatic confinement (IEC).
This design came from work by Philo T. Farnsworth in 1964 and Robert L. Hirsch in 1967.

Video camera tube

He is 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.
The term may apply specifically to a dissector tube employing magnetic fields to keep the electron image in focus, an element lacking in Dieckmann and Hell's design, and in the early dissector tubes built by American inventor Philo Farnsworth.

In later life, Farnsworth invented a small nuclear fusion device, the Farnsworth–Hirsch fusor, employing inertial electrostatic confinement (IEC).
In his work with vacuum tubes, Philo Farnsworth observed that electric charge would accumulate in regions of the tube.

Many inventors had built electromechanical television systems before Farnsworth's seminal contribution, but Farnsworth designed and built the world's first working all-electronic television system, employing electronic scanning in both the pickup and display devices.
On September 7, 1927, Philo Farnsworth's image dissector camera tube transmitted its first image, a simple straight line, at his laboratory at 202 Green Street in San Francisco.

In 1931, David Sarnoff of RCA offered to buy Farnsworth's patents for US$100,000, with the stipulation that he become an employee of RCA, but Farnsworth refused.
Zworykin had visited the laboratory of the inventor Philo T. Farnsworth, who had developed an Image Dissector, part of a system that could enable a working television.

Farnsworth Television and Radio Corporation was purchased by International Telephone and Telegraph (ITT) in 1951.
In 1951, ITT purchased Philo Farnsworth's television company to break into that market.

John Logie Baird

In 1932, while in England to raise money for his legal battles with RCA, Farnsworth met with John Logie Baird, a Scottish inventor who had given the world's first public demonstration of a working television system in London in 1926, using an electro-mechanical imaging system, and who was seeking to develop electronic television receivers.
Similarly, Philo T. Farnsworth's electronic "Image Dissector" camera was available to Baird's company via a patent-sharing agreement.

Photoelectric effect

photoelectricphotoelectronphotoemission
Most television systems in use at the time used image scanning devices ("rasterizers") employing rotating "Nipkow disks" comprising a spinning disk with holes arranged in spiral patterns such that they swept across an image in a succession of short arcs while focusing the light they captured on photosensitive elements, thus producing a varying electrical signal corresponding to the variations in light intensity.
Video camera tubes in the early days of television used the photoelectric effect, for example, Philo Farnsworth's "Image dissector" used a screen charged by the photoelectric effect to transform an optical image into a scanned electronic signal.

Analog high-definition television system

Host Garry Moore then spent a few minutes discussing with Farnsworth his research on such projects as an early analog high-definition television system, flat-screen receivers, and fusion power.
John Logie Baird, Philo T. Farnsworth, and Vladimir Zworykin had each developed competing TV systems, but resolution was not the issue that separated their substantially different technologies, it was patent interference lawsuits and deployment issues given the tumultuous financial climate of the late 1920s and 1930s.

One of Farnsworth's most significant contributions at ITT was the PPI Projector, an enhancement on the iconic "circular sweep" radar display, which allowed safe air traffic control from the ground.
Philo Taylor Farnsworth, the American inventor of all-electronic television in September 1927, contributed to this in an important way.

The award is named after Philo T. Farnsworth, a pioneer of electronic television technology.

Farnsworth Peak

The mountain is named for Philo Farnsworth, the inventor of the first completely electronic television.

Iconoscope

Zworykin later abandoned research on the Image Dissector, which at the time required extremely bright illumination of its subjects, and turned his attention to what became the Iconoscope.
One year later, in 1933, Philo Farnsworth also applied for a patent for a device that use a charge storage plate and a low-velocity electron scanning beam, a patent was issued in 1937, but Farnsworth did not know that the low-velocity scanning beam must land perpendicular to the target and he never actually built such a tube.
