Vision Based Laser Receiver

Laser receivers are used in conjunction with rotating laser levels for control of grading equipment, and areas for improvement include the length and cost of the sensing element.  


My task was to find an embodiment for the concept of using image analysis to interpret the laser strike on a conical surface where the effective diameter of the strike in the image corresponds to the vertical location of the strike on the cone.

Challenges for this design included sufficient depth of field for a camera to capture images along the entire length of the cone and achieving sufficient contrast to interpret the image of the strike.
