A debris detection system includes a chamber configured to permit particles to pass through the chamber; an optical fiber or fiber optic cable providing a light path; a collimator configured to channel light from the light path into the chamber; and a reflector configured to reflect light back to the collimator for signal detection. In embodiments, the reflector may include a mirror. Methods for detecting particles and information and/or parameters associated with particles, including that associated with reflected light, are disclosed.

Liquid debris sensor and system

A method of operating an electro-optic sensor includes disposing at least a portion of the electro-optic sensor in a liquid chamber, providing light from a light source of the electro-optic sensor at a first intensity, driving a light detector of the electro-optic sensor at a first sensitivity level, receiving, via the light detector, a first amount of light from the light source; determining whether liquid is present in the liquid chamber according to the first amount of light, providing light from the light source at a second intensity, driving the light detector at a second sensitivity level, receiving, via the light detector, a second amount of light from the light source, and/or confirming whether liquid is present in the liquid chamber according to the second amount of light. The first sensitivity level may be different from the second sensitivity level. An electro-optic sensor is also disclosed.
