Abstract
A rotatable optical module able to aim structured light in different directions includes a driver and an optical assembly positioned at a side of the driver and connected to the driver. The optical assembly projects structured light. The driver drives the optical assembly to rotate, thereby changing the aiming direction of the structured light. An electronic device using such module and placed directly between two target objects is able to function as a meter of the distance between the objects in addition to mapping the contours of each.
