Abstract

In an IR proximity-based motion gesture sensor (MGS) mainly composed of an IR LED and photodiodes (PDs), the IR LED is the most power-hungry component. For reducing its power, both the size and the field-of-view (FOV) of each PD can be increased instead. However, it cannot be adapted to conventional MGSs due to the geometrical limitation of their optical structures. In this paper, the optical structure of the proposed MGS with a partially open cavity package allows for power reduction by at least 70.9% compared with conventional MGSs. Optical simulation and test results validate the theoretical analysis presented.
