Abstract
A fast spatial light modulator based on a linear MEMS ribbon array enables a depth capture system to operate in structured light and time-of-flight modes. Time-of-flight depth information may be used to phase unwrap structured light depth information. Combined structured light and time-of-flight systems offer precise depth resolution over a wide range of distances.
