  • Patent number: 9823115
    Abstract: A packaged optical device includes a light source device emitting light to an object surface, a sensor chip receiving reflective light reflected from the object surface, and a non-lens transparency layer located in front of the sensor chip. The light and the reflective light have a first main optic axis and a second main optic axis, respectively, and the first main optic axis and the second main optic axis are configured to form the specular reflection configuration, thereby enhancing images received by the sensor chip. The non-lens transparency layer has a zone passed through by the second main optic axis, and transmittance of the zone is lower than that of other zones of the non-lens transparency layer, thereby preventing the sensor chip from being saturated.
