A unit load device (ULD) sensor for detecting presence and movement of cargo within an aircraft includes a light source designed to generate light as pulses with pulse intervals between the pulses and having a source lens designed to focus the light towards a first point that is a first distance away from the source lens. The ULD sensor also includes a light receiver having a light detector designed to receive a reflection of the light and a receiver lens designed to focus the reflection of the light towards a second point that is towards the light detector and a second distance away from the receiver lens. The second distance is different than the first distance and the detected reflection of the light is usable to determine the presence and the movement of the cargo.
