Abstract
Methods and apparatus for quantifying the amount of backlash in drive trains. Using two optical transducers techniques are disclosed that lend themselves to self diagnosis of backlash in drive train systems. The techniques are useful in autochanger drive systems, but are also applicable to all systems involving the driven motion of devices.
