摘要：
A portable electronic device includes a switching unit, a light source, a light detector and control unit. The user utilizes the switching unit to select the detection mode. The light is emitted from the light source to the object to generate a reflected light. The light detector detects the reflected light to generate a light detecting signal for the control unit to calculate a corresponding result based on the selected mode. Therefore, single portable electronic device can achieve multiple functions and is more convenient for utilization.
