Some edges, such as the one depicted to the left, have retroreflector panels.

For more sensitive vision in low light, some fish have a retroreflector behind the retina.

For safety, the taillight also has been designed with the addition of a retroreflector device.

Part of the surface of the garment may have retroreflector stripes.

This allows aiming without a retroreflector for short ranges.

In both cases, laser pulses were returned from the Lunokhod 1 retroreflector.

In addition, standalone retroreflector batons are often used on the verge of Irish roads.

Lunar laser ranging experiments had failed to detect a return signal from its retroreflector since the 1970s.

The tapetum lucidum is a retroreflector of the transparent sphere type.

Because it is a retroreflector, it reflects light directly back along the light path.

The mass includes a retroreflector and terminates one arm of a Michelson interferometer.

The "blade" was three-sided and coated with a retroreflector array, the same sort used for highway signs.

What makes Meteor 2-21 distinctive from the other meteorological satellites is its unique retroreflector array.

The satellite is also equipped with a laser retroreflector to enable tracking by ground-based lasers.

Sheeting has replaced button copy as the predominant type of retroreflector used in roadway signs.

A simple retroreflector can be made by placing three ordinary mirrors mutually perpendicular to one another (a corner reflector).

These applications required special retroreflector labels.

A safety reflector is a retroreflector intended for pedestrians, runners, motorized and non-motorized vehicles.

A set of three mutually perpendicular reflective surfaces, placed to form the corner of a cube, work as a retroreflector.

A third, much less common way of producing a retroreflector is to use the nonlinear optical phenomenon of phase conjugation.

In surveying, retroreflector prisms are commonly used as targets for long-range electronic distance measurement using a total station.

Secondary mission objective is the flight testing of the novel-type spherical retroreflector for precise laser ranging.

Alternatively, the source and receiver are combined, and the beam bounced off a retroreflector at the far end of the measurement path.
