Module Notes Flashcards
What is “Level”?
To level means to put into the same plane as the horizon.
What is “Flat”?
To put on same plane
(may be level)
(may be flat on incline - like conveyor)
What is straight?
To be in direct line(straightness)
What is square?
Something the is aligned 90 degrees to a reference line
L
Shooting through hot or cold air causes _______ of the image.
Shooting through glass ______ the line of sight and gives false readings.
Distortion
Refracts
Regardless of the angle at which the incident ray enters, the refracted ray leaves at exactly 90 degrees. What is this?
Pentaprisms
-optical square
Auto = ?
Reflection = ?
Auto = using a mirror
Reflection = Target
Auto = ?
Collimation = ?
Auto = Using a Mirror
Collimation = Light
*most accurate
What is a coincidence striding level?
Coincidence Striding Level is used on an alignment telescope or collimator to establish the tool in a level position.
What are lateral adjusters used for?
Bucking In Targets (lining up with targets)
What is bucking in?
Process of aligning an optical tool onto two targets at the same time. (Precision Lateral Adjuster)
What is the primary purpose of a jig transit?
To sweep a vertical line
Alignment telescopes can be used to establish? (3 points)
-Level reference line using coincidence striding level
-Vertical reference using special plumb aligner bracket
-Plane Perpendicular to a reference line using optical square.
What is required of your instruments before setting up and taking measurements?
Acclimatizing the instruments is required to ensure accurate readings with a temperature change.
3 types of laser alignment systems;
Single reflected beam with single detector(auto-collimation)
Dual beam with dual detectors
Single beam with dual detectors
