Abstract
Techniques are disclosed for providing proper raster line alignment of a camera or other light-sensing device of a receiver device relative to a transmitting light-based communication (LCom)-enabled luminaire to establish reliable LCom there between. In accordance with some embodiments, proper alignment can be provided automatically (e.g., by the receiver device and/or other suitable controller). In accordance with some embodiments, proper alignment can be provided by the user. In some instances in which a user is to be involved in the alignment process, the receiver device may be configured, for example, to instruct or otherwise guide the user in the process of properly aligning the receiver device relative to a given transmitting LCom-enabled luminaire.
