Detection method

  1. Sep 9, 2009 #1

    Just a query...

    what is the differences between this types of detection and their usage?
    a) heterodyne
    b) differential
    c) normal
    d) homodyne?

    We don't do homework assignments.

    Just go to Wikipedia or Google and look them up.


    Even your text book from school will have nice diagrams and a carefully written explanation.

    not a homework assignment....

    actually i am more concerned with the timing detection requirement of differential detection... for a heterodyne detection, we need to capture 2 cycle of change to determine the heterodyne signal..what about differential?

    also for homodyne and heterodyne detection... heard there is a difference in the terminology between optical and electrical homodyne/heterodyne..what/why the diff?
