Laser Autocollimator basics
What is Laser Autocollimator ?
The laser autocollimator is a non-contact real-time measuring instrument by a laser beam for measuring
small angles on a subject or relative angles over multiple subjects.
small angles on a subject or relative angles over multiple subjects.
Measuring Principle
When a collimated beam passes through a condense lens,the incident
angle can be converted to position data of a targeted plane. The same
principal applied, it projects an collimated laser beam to reflect at a
measuring target and is condensed at CMOS, then, it measures the tilt
angle of an target.

Do you manipulate a number of displacement sensors for "measuring angle"?
Displacement Sensor
The three displacement sensors measure angles of a lane.
・Not suitable for micro-devices
・Overheads for calculating angles
・Demanding "cost" and "space" for three devices
