Abstract
In order to sense an object or a person in the interior of a vehicle, a laser emits a laser pulse. The laser pulse which is reflected at an object or a person is registered and evaluated. The energy content of a following laser pulse is determined based on a characteristic variable of the reflected laser pulse such as its power or its energy content.
