1. A system for identifying motion of a target, comprising: one or more transmitters for transmitting one or more light beams at the target; one or more receivers for receiving reflection of the one or more light beams from the target; one or more memory devices for storing instructions; and one or more processor devices that execute the instructions that enable actions, including: employing detection of one or more reflected light beams by the one or more receivers to employ the one or more transmitters to modulate the one or more light beams transmitted onto the target; employing the one or more receivers to generate one or more signals based on detection of the reflection of the one or more light beams; employing the one or more transmitters to dynamically modify an illumination intensity of the one or more light beams based on a reflection of one or more light patterns by different detected textures of one or more surfaces of the target; and providing one or more characteristics of a relative velocity between the target and the one or more receivers based on the one or more signals.
