Abstract : Remote measuring of an angle is very difficult if the angle to be measured is in the plane containing the observer. This patent application describes a technique using cylindrical lenses and patterns which provide a binary coded image to the remote observer. The binary code read out is the angle in the plane containing the observer. Use of microscreens allows the system to be very thin, and even curved around a curved surface, such as a missile. It can be used to continuously record the yaw angle of a missile during test flight.
