Histor of the printer?
In 1953, the first high-speed printer was developed by Remington-Rand for use on the Univac computer. In 1938, Chester Carlson invented a dry printing process called electrophotography commonly called a Xerox, the foundation technology for laser printers to come. The original laser printer called EARS was developed at the Xerox Palo Alto Research Center beginning in 1969 and completed in November, 1971. Xerox Engineer, Gary Starkweather adapted Xerox copier technology adding a laser beam to it to come up with the laser printer. According to Xerox, "The Xerox 9700 Electronic Printing System, the first xerographic laser printer product, was released in 1977. The 9700, a direct descendent from the original PARC "EARS" printer which pioneered in laser scanning optics, character generation electronics, and page-formatting software, was the first product on the market to be enabled by PARC research." According to IBM, "the very first IBM 3800 was installed in the central accounting office at F. W. Woolworth's North American data center in Milwaukee, Wisconsin in 1976." The IBM 3800 Printing System was the industry's first high-speed, laser printer. A laser printer that operated at speeds of more than 100 impressions-per-minute. It was the first printer to combine laser technology and electrophotography according to IBM. In 1992, Hewlett-Packard released the popular LaserJet 4, the first 600 by 600 dots per inch resolution laser printer. In 1976, the inkjet printer was invented, but it took until 1988 for the inkjet to become a home consumer item with Hewlett-Parkard's release of the DeskJet inkjet printer.
When was laser tag invented?
1982The Commercial Laser Tag IndustryIn 1982, entrepreneur George A Carter III—inspired by Star Wars—created the first scored arena-based laser tag game. Two years later, he opened the first Photon laser tag center, in Dallas. Multiple locations soon followed, and the rise of commercial laser tag was officially underway
What was the earliest model of LASER and what was it called?
Because the initial work on "Amplification by Stimulated Emission of Radiation" (ASER) had been done on microwaves and such a device was thus named the MASER, the earliest work on what is now called the LASER referred to them as the "optical MASER". On May 16, 1960, Theodore H. Maiman operated the very first functioning LASER at Hughes Research Laboratories, Malibu, California. Maiman's LASER used a solid-state flashlamp-pumped synthetic ruby crystal to produce red light, at 694 nanometers wavelength; however, the device was only capable of pulsed operation, because of its three-level pumping design scheme. Later that year, Ali Javan, and William R. Bennett, and Donald Herriott, constructed the first gas LASER, using helium and neon that was capable of continuous operation in the infrared (U.S. Patent 3,149,290 Bell Labs).
What is laser engraving?
Generally, laser engraving machine has three main parts: a laser, a controller, and a surface. The laser is like a pencil - the beam emitted from it allows the controller to trace patterns onto the surface. The controller (usually a computer) controls the direction, intensity, speed of movement, and spread of the laser beam aimed at the surface. The surface is picked to match what the laser can act on.
In a laser printer the laser beam is initiated and directed toward the octagonal mirror called the mirror?
The laser beam in a laser printer is initiated from a laser diode, not a mirror. The laser beam is then directed by a rotating polygon mirror, not an octagonal mirror, which reflects the beam onto the drum surface to create the print image through a process called electrostatic printing.
What are laser avengers called?
Laser avengers are called laser humvee's but laser humvee's are also called laser vehicles. Laser vehicles can destroy missiles, bombs, aircraft, aircraft drones, ships and other lands vehicles.
Working of laser surface treatment of metals?
In laser surface treatment of metals, a high-intensity laser beam is focused on the metal surface, causing rapid heating and melting of a thin surface layer. This process can modify the surface properties of the metal, such as hardness, wear resistance, and corrosion resistance. By controlling the laser parameters, such as power, speed, and duration, specific surface properties can be achieved without affecting the bulk material properties.
Are laser avengers called laser humvee?
Yes.
Can you cut ice with lasers?
Yes, lasers can be used to cut ice by rapidly melting it through a process called laser ablation. This involves focusing the laser beam onto the ice surface to generate enough heat to melt and vaporize it, allowing for precise cutting without physical contact.
Can you damage a TV with a laser pen?
You can burn the surface of an LCD or plasma display with a laser that is either high intensity (Over 5 mw) or had its infrared filter removed. But then you can burn the surface of most plastics with a 50 mw laser pen.
What is a laster cutter?
laser cutter? laser cutter can be thought of as three main parts: a laser, a controller, and a surface. The laser is like a pencil - the beam emitted from it allows the controller to trace patterns onto the surface. The controller (usually a computer) controls the direction, intensity, speed of movement, and spread of the laser beam aimed at the surface. The surface is picked to match what the laser can act on.laser engraving machineThere are three main genres of : The most common is the X-Y table where, usually, the workpiece (surface) is stationary and the laser optics move around in X and Y directions, directing the laser beam to draw vectors. Sometimes the laser is stationary and the workpiece moves. Sometimes the workpiece moves in the Y axis and the laser in the X axis. A second genre is for cylindrical workpieces (or flat workpieces mounted around a cylinder) where the laser effectively traverses a fine helix and on/off laser pulsing produces the desired image on a raster basis. In the third method, both the laser and workpiece are stationary and galvo mirrors move the laser beam over the workpiece surface. Laser engraving machine using this technology can work in either raster or vector mode.
What can produce 3d images of the surface of the objects?
Laser interference
What is a laser profilometer used for?
A laser profilometer is used for construction control surveys. Laser profilometers are non contact instruments, meaning they don't need to touch the surface.
How does a Laser Triangulation Sensor work?
A Laser Triangulation Sensor is a device for measuring heights. Basically, you point a laser beam directly at a surface, is reflected and falls on the sensor, through the lens. Depending on the beams position on the sensor, the angle towards the surface is calculated.
