Abstract
This paper describes a microbend amplitude sensor for measurement of engine internal combustion pressure. Utilizing a step index singlemode fiber in a spark plug washer-type configuration, it is a simple, sensitive and rugged design. The microbending element, composed of two serrated washers constraining an optical fiber loop, responds to spark plug displacement arising from the combustion cycle. The response of the sensor is linear in dB with displacement and force over a wide dynamic range. We compare performance under static and running engine conditions with a research grade piezoelectric diaphragm sensor and a piezoelectric washer-type sensor.
