Linear variable reflector sensors can be used to measure the displacement
of objects. These sensors are useful in that they can be very small, do
not conduct electricity, and are resistant to electrical interference
from EMI/EMP and lightning strikes. The present linear variable reflector
system comprises a light source, a light transmitting member in optical
communication with the light source, a sensor in optical communication
with the light transmitting member. The sensor comprises a moveable
transparent body, a reflective material deposited on the transparent
body, and at least one film deposited over said reflective material,
wherein said reflective material reflects light. Further, the linear
variable reflector system comprises a detector coupled to the sensor to
detect displacement of the moveable transparent body.
