Angular measurements

The PICOSCALE allows angular measurements in two dimensions, such as yaw and pitch of a target object.

Furthermore SmarAct provides a special 1″ sensor head assembly containing three sensor heads and retroreflectors. Every assembly comes with detailed information about the beam distance and parallelity.

Angular Measurement Range -13° ≤ φ(x) ≤ 13°
Angular Measurement Range 2D | φ(x,y) | ≤ 8°

Application example

The head assembly is measuring the tip and tilt of an appropriate target consisting of three retro-reflectors, mounted to a gimbal mount based on SmarAct nanopositioners. The angular movement could be tracked with an angular resolution down to the μ° level. Angles were calculated in real-time using the Calculation System module with minimal timing delay.
