Abstract
A method an apparatus are provided for inspecting the surface of objects such as panels for automobile vehicles wherein the surface of the object is sprayed with an oil mist or the like to increase the reflectivity thereof. The surface is then illuminated with light so that the light image reflected therefrom is formed on a light detector such as a photodiode array. The output of the light detector is analyzed to determine surface features of the object such as 'dings' and dents therein.
