Abstract
A biometric measuring device measures distances between selected elements in a human body, and in particular, the human eye. Trace means produces respective signals for a preselected number of cycles wherein each signal represents the distance between the selected elements that is to be measured. Converting means averages the respective signals over the preselected number of cycles to produce a distance signal representing the distance between the selected elements of the body. Display means displays this distance signal as a number.
