Disclosed is an electronic apparatus comprising a mounting portion to which one of a plurality of optical heads is selectively mountable; a communicator configured to communicate with an external apparatus; an optical module (optical unit) configured to transmit light, which is reflected from a user's body and passed through the optical head mounted to the mounting portion, to the external apparatus; and a controller configured to obtain identification information about the optical head mounted to the mounting portion when one of the plurality of optical heads is mounted to the mounting portion, and control the communicator to transmit the identification information to the external apparatus.
Thus, a desired optical head is mounted as necessary to capture an image of a user's body part, analyze the captured image, and provide analysis information to a user.
