An object reflects certain amount of light falling on it. When this reflected light enters our eyes, we are able to see it. A transparent glass object lets almost all the light falling on it to pass through. That’s why we are able to see through it. Opaque objects do not let light to pass through themselves. They absorb and reflect most light that falls on them. A mirror reflects most of the light that falls on its surface. That’s why it is able to produce an image of an object. Generally, highly polished surfaces reflect more amount of light falling on them. In this section we will be looking at the reflection of light from various surfaces.

In machine vision, lighting serves as the source of illumination for cameras and other imaging devices along with other techniques like polarization.
