    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.

    Abstract: An embodiment may provide a method for synchronizing a field of view of a distance measuring device including: a light source including one or more light source elements; and a light diffusion device through which light emitted from the light source passes, wherein the light diffusion device is divided into one or more regions, each of the light source elements of the light source is disposed with an independent region, and the intensity of light transferred from the light source elements is adjustable. The method may include: identifying a field of view (FOV) of a red, green, and blue (RGB) camera; and adjusting, based on a predetermined reference, the field of view of the distance measuring device such that the field of view of the distance measuring device corresponds to the field of view of the RGB camera.
