2. Laser line level - Wikipedia

   en.wikipedia.org/wiki/Laser_line_level

   A laser line level is a tool combining a spirit level and/or plumb bob with a laser to display an accurately horizontal or vertical illuminated line on a surface the laser line level is laid against. Laser line levels are used wherever accurate verticals and horizontals are required, typically in the construction and cabinetry industries. Some ...

3. Laser level - Wikipedia

   en.wikipedia.org/wiki/Laser_level

   The concept of a laser level has been around since at least the early 1970s, [2] the original spinning-mirror design laser plane and line level was patented by the late 1980s, [3] and the compact lens-based laser line level (as produced by many tool manufacturers today) was patented in the late 1990s. It was invented by Oscar Soliz in the late ...

4. Phased-array optics - Wikipedia

   en.wikipedia.org/wiki/Phased-array_optics

   Phased-array beam steering is used for optical switching and multiplexing in optoelectronic devices and for aiming laser beams on a macroscopic scale. Complicated patterns of phase variation can be used to produce diffractive optical elements , such as dynamic virtual lenses, for beam focusing or splitting in addition to aiming.

   Walmart (WMT) has put out an APB for shoppers: "We have the lowest prices all the time. Period." This week, the nation's biggest retailer detailed its $2 billion plan to "reinvest" in low prices ...

6. Laser machine control - Wikipedia

   en.wikipedia.org/wiki/Laser_Machine_Control

   The laser receiver detects the height of laser plane with an array of photo diodes, generally a series of photo diodes in 9" strip with a gap between diodes equal to the width of the beam. the receiver reads the height with the sensors and convert to a usable analog or digital signal and sends to the machine control unit. Modern systems use CAN ...

7. Line laser - Wikipedia

   en.wikipedia.org/wiki/Line_laser

   Line laser with interchangeable lenses A line laser is a device that employs a laser and an optical lens to project the laser beam as a line rather than a point (e.g. laser pointer ). This may be achieved by passing the beam through a cylindrical lens or a Powell lens.
