They're basically an optical projector
that displays an informationally compressed flight data display on a glass screen called a combiner.
An optical projector
is offset 100 mm to the right (horizontally) and 6.7 mm down (vertically) from an optical receiver.
Using an optical projector
and a CCD camera to acquire information regarding dimensions and position of the part to be inspected, these measuring devices are the top of the arrow of the dimensional measurements industry.
NIST measured the tilt angle with an optical projector
to verify the USBR procedures for tilt-angle measurement.
"One particular area beneficial to our customers is our on-site accreditations, ie surface plate calibration, optical projector
calibration, pressure and temperature.
(see figure 2) Use an optical projector
to magnify the surface finish and see this condition, which is similar to a thread.
After finishing, the optical projector
and DRO come into play again, for inspecting the part.
The following services will be presented in government schools for the first time in Egypt: modern computers, optical projectors
, wireless controllers, and tablets, which students will use for classroom participation.
"For instance, in the past, companies have willingly paid to have calibration engineers travel from areas in the south to perform calibrations on instruments such as optical projectors
, surface plate calibration and refurbishment or instrumentation panels containing pressure and or temperature indicators.
