<p>In an embodiment, a method of detecting at least one optical characteristic of a medium may be provided. The method may include transmitting an input light of a light source having a reference time varying intensity waveform through the medium; detecting a resultant light having a resultant time varying intensity waveform at an optical detector; determining a time-based characteristic corresponding to an intensity characteristic relating to the respective reference time varying intensity waveform and the resultant time varying intensity waveform when the input light is being transmitted from the light source to the optical detector; and determining the at least one optical characteristic of the medium based on the time-based characteristic. A method of detecting presence of a medium between a light source and an optical detector may also be provided.</p> |
