Abstract
A sensing device for measuring an offset along a longitudinal axis comprises a housing including a plurality of slots, two or more arrays of optical sensors aligned along the longitudinal axis, at least one of the arrays being offset along the longitudinal axis with respect to the other arrays and a microcontroller coupled to the two or more arrays of optical sensors and configured to determine a positional offset along the longitudinal axis at which light is detected by at least one of arrays of optical sensors. In some embodiments, each of the optical sensors of the arrays are positioned within the housing underneath one of the plurality of slots to reduce an angle of incidence of radiation received.
