ABSTRACT:
An optical theta-modulation based analog-to-digital converter having an acousto-optic deflector and an analog-to-digital conversion mask, for fast and flexible analog-to-digital conversion. The acousto-optic deflector deflects an optical beam at an angle corresponding to an input voltage signal having an analog value. The analog-to-digital conversion mask converts the deflected optical beam into N masked optical signals which each corresponds to a respective bit of a digital value representing the analog value of the input signal. Each optical signal is detected by a photodetector and converted into an output voltage signal by a comparator.
