More Information
Summary:An optical sensing apparatus is provided and includes a circuit board, a signal emitter and a signal receiver are disposed on the circuit board, respectively. A package structure covers the signal emitter and the signal receiver and divided thereof by a first opening, and provided a second opening on top of the signal receiver. The scattering path of the light generated by the signal emitter is changed by the first opening and the second opening to decrease probabilities that the light generated by the signal emitter is directly transmitted to the signal receiver. The sensing accuracy of the optical sensing apparatus is increased to reduce the effect of the crosstalk.
