Abstract
A method and apparatus for developing a digital signal that represents the profile of a movable part such as a bolt. The part is moved by a part carrier between a source of radiant energy and a sensor and the sensor develops a voltage that is a function of the profile of the part. This voltage is processed by a programmed microprocessor. The processing of the voltage and the microprocessor operates to develop a digital representation of the part that does not vary with the changes in speed of the part. The part carrier is moved between the source and sensor and voltage variations due to vertical motion of the part carrier are compensated.
