    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: An electronic circuit for operating a High Intensity Discharge (HID) lamp, in particular a Ultra High Pressure (UHP) lamp, such as those preferably used in image projectors. The circuit comprises a lamp ballast for offering a controlled lamp current for operating the HID lamp and a brightness sensor for generating and providing a sensor signal which represents the brightness of the light applied by the lamp to the image generator. The lamp ballast controls the lamp current such that the brightness of the light of the lamp remains constant. Brightness control is made possible throughout the entire operational life of the lamp, and the use of sensors of simple construction is made possible by an incorporation within the electric circuit of a filter that high-pass filters the sensor signal before it is supplied as a control signal to the lamp ballast.

    摘要: The invention relates to a method of representing a video image based on a video signal by means of a projector which comprises an image display device and a high-pressure gas discharge lamp, which lamp is supplied with a square-wave alternating current (I0, I10) on which a current pulse (P1, P3, P10, P40) is superimposed before each phase reversal. According to the invention, the alternating current (I0, I10) is superimposed with a second current pulse (P2, P4, P20, P30, P50, P60) of the same polarity. A simple attunement of the alternating current frequency to the image frequency without image artifacts is made possible by the second pulses (P2, P4, P20, P30, P50, P60).

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.
