Reference pixel array with varying sensitivities for TOF sensor |
摘要 |
<p>The sensitivity of a reference pixel array RPA to the reference modulated light MLR is varied for different reference pixels RP of the reference pixel array RPA. In one embodiment the different sensitivities of the reference pixels RP in the RPA is achieved by designing the pixels to have different light sensitivities with respect to each other. In another embodiment, the different sensitivities are achieved by changing optical coupling between the separate reference pixels RP of the reference pixel array RPA to the reference modulated light MLR such as by changing how the different reference pixels RP couple to the aperture LGA of the light guide LG.</p> |
