    摘要: A method for driving a high-pressure gas discharge lamp of a projector system, which is suitable to produce and to supply to a light valve device during a projection interval (4) a light beam of a basic color which is selected from several basic colors (G, R, B). The lamp is driven by a lamp current. During said projection interval light valves of the light valve device are controlled in a pulse width modulation manner to have each valve provide a respective wanted light integral over said projection interval. During at least one of a number of successive projection intervals associated with one basic color a magnitude of the lamp current is temporarily reduced for at least a time that all light valves can be controlled for said one basic color.

    摘要: The invention relates to a velocity determination apparatus for determining a relative velocity between a first object (12), to which the velocity determination apparatus is attachable, and a second object (1). The velocity determination apparatus comprises a laser (3) having a laser cavity (4) for emitting first radiation (5), which is reflected by the second object (1), wherein the reflected radiation interferes with the first radiation (5) within the laser cavity (4). An interference signal detector (7) detects an interference signal depending on the interference within the laser cavity (4) and a velocity determination unit (8) determines the relative velocity based on the interference signal. A reliability value determination unit (9) determines a reliability value for indicating the reliability of the determined relative velocity based on at least one of the group consisting of the detected interference signal, the determined relative velocity and a characteristic of the laser.
