Abstract

We present a time-of-flight (TOF) ranging experiment
based on optical mixing. The key component in this experiment is
the optical (de)modulator. Consequently we also report on the design,
fabrication, and characterization of a microelectromechanical
system diffractive grating (de)modulator with a subwavelength
period. The obtained results are an important step toward an optical
mixing based TOF 3-D imaging system, which we will further
develop in our future work.
