An optical head that can be easily assembled is for reading an image of an object and includes a housing, a diffuser, a light source module and a light sensing module. The diffuser is connected to the housing. The light source module has a substrate and a first light source mounted on a front side of the substrate. The front side of the substrate is fixed to an external surface of the diffuser. The first light source provides an initial light ray incident to the diffuser. The diffuser processes the initial light ray into uniform light for output. The light sensing module fixed in the housing senses reflected light, which is generated from the uniform light reflected by the object.

Optical head for reading an image of an object

An optical head for reading an object includes a hollow housing, a light source module, a diffuser structure and a light sensing module. The light source module is fixed in the hollow housing and provides an initial light ray. The diffuser structure is connected the hollow housing, receives the initial light ray, and processes the initial light ray into a uniform light ray for output. The initial light ray is reflected by the diffuser structure multiple times to form the uniform light ray. The light sensing module is fixed in the hollow housing and senses the uniform light ray reflected by the object. An optical axis of the light sensing module is substantially parallel to an axial direction of the diffuser structure.
