Systems and methods for generating a position reference grid and relative positioning of an object are presented. Radiation is emitted towards a digital micro-mirror device including a plurality of micro-mirrors. Additionally, one or more of a plurality of micro-mirrors are modulated such that at least a portion of the radiation reflected from the plurality of micro-mirrors is projected on to a designated location in a designated pattern representative of a position reference grid. The radiation reflected from the plurality of micro-mirrors is detected. Further, the detected radiation is interpreted as location coordinates in the position reference grid. Additionally, the location coordinates are communicated to the object moving in relation to the digital micro-mirror device for positioning the object at a designated position in the position reference grid.
