Abstract
An embodiment apparatus for detecting a material of a vehicle body part includes a light source configured to emit an emission light toward the vehicle body part, an optical sensor configured to detect a reflection light generated by reflection of the emission light at the vehicle body part and to generate a detection current according to an intensity of the reflection light, a case enclosing the light source and the optical sensor, and a control circuit configured to convert the detection current to a detection voltage, to determine a material of the vehicle body part as a first material in response to the detection voltage being greater than or equal to a reference voltage, and to determine the material of the vehicle body part as a second material in response to the detection voltage being less than the reference voltage.
