ABSTRACT:
A method of fabricating optical sensing devices for detecting displacement of a part thereof comprising the steps of bonding a multiplicity of optical devices to one surface of a relatively large transparent substrate so that the optical devices are accurately located relative to one another and to the substrate itself, securing to the opposite surface of the substrate and one surface of a transparent optical element-carrying substrate in parallel relationship thereto resilient spacer support means and dividing the entire assembly into individual unit parts each of which comprises an optical device bonded to one substrate unit and coupled to another substrate unit having its own optical element by a divided part of the resilient spacer support means so that the two substrate units are resiliently mounted relative to one another whereby relative movement between the two substrate units produces variations in the optical characteristics of the device which can be sensed.
