    Abstract: An optical package has a light source module including a light source, a first component for driving the light source, and a light source board having a first side on which the light source is stacked and a second side on which the first component is under-stacked. The optical package has a main board in which a first region is open and to which the light source module is coupled so that the first component is positioned in the first region. Also, the optical package has a sensor module including an optical sensor board disposed to be spaced apart from the main board through a spacer, thereby defining a separation space, and a second component disposed in the separation space.
