Abstract
An optical transducer includes a base member, a light source carried on a face of the base member, a light detector carried on the face of the base member, a displaceable member overlying and spaced from the light source and light detector and effective to reflect light from the light source to the light detector, and light shielding means effective to shield the light detector from exposure to the light source except for the light reflected by the displaceable member from the light source to the light detector. The light detector is configured to substantially surround the light source such as to receive light emitted in substantially all directions from the light source for reflection to the light detector by the displaceable member.
