SYSTEMS AND METHODS FOR OPTICAL TRACKING OF HIGH PRECISION

Introduced here is a system for optically tracking displacement with high precision across one or more axes. To track displacement of an object, images that are generated by a plurality of optical sensors can be compared against one another. For example, images that are generated by a first optical sensor can be compared against images that are generated by a second optical sensor. Because the first and second optical sensors are in a fixed spatial relationship with one another, displacement of the object can be established based on the degree to which a given image generated by the first optical sensor matches another image generated by the second optical sensor.
