An optical communication device can address these and other issues by utilizing a system and method in which an optical device (110) emits a series of laser pulses that trace a spiral path over a coverage area. Each laser pulse containing a packet of information modulated at a relatively rate to help mitigate adverse effects from device movements, scintillation, and the like. The beam width of the laser, speed of the scan (along the spiral path), and number of laser pulses can be configured such that corresponding response pulses (e.g., retro-modulated pulses) received from an illuminated tag within the coverage may have a variety of different amplitudes, increasing the likelihood that at least one of the response pulses will have power characteristics that facilitate a proper decoding of the response pulse.
