ABSTRACT:
An apparatus accurately measures the time difference between two signal edges by optically detecting the emission from a “beacon device” that is modulated as a function of time difference. Through the use of this modulation it is possible to perform timing measurement accurately. Embodiments of a voltage modulator circuit modulate timing information into emission intensity. The method and system of the present invention can be used in applications such as clock skew and pulse width measurements.
