1. An object shape detection apparatus comprising:
a transmitter configured to emit horizontally polarized and vertically polarized wave components of an electromagnetic wave;
a receiver configured to receive horizontally polarized and vertically polarized wave components of a reflected wave, the reflected wave being a reflection of the electromagnetic wave from an object after the electromagnetic wave is emitted by the transmitter; and
at least one circuit or processor configured to:
compare an intensity of the horizontally polarized wave component of the reflected wave to an intensity of the vertically polarized wave component of the reflected wave, and
determine a shape of a raised portion on a surface of the object or a shape of a depressed portion on a surface of the object based on the compared intensities.
