Abstract: A sensor module (1) for measuring the distance to a target and/or the velocity of the target (50), the sensor module (1) comprising at least one laser source (100), at least one detector (200) being adapted to detect modulated laser light and at least one control element the control element (400) being adapted to vary the focus point of the laser light and/or the intensity of the laser light and/or the direction of the laser light. The control of the laser light emitted by the laser source (100) either by active optical devices as variable focus lenses or controllable attenuators or passive optical elements in combination with arrays of laser sources (100) and detectors (200) enable flexible and robust sensor modules.

Abstract: The invention relates to a mercury-free molecular discharge lamp (30), which comprises: a light-transmitting discharge vessel (32) enclosing, in a gastight manner, a discharge space comprising a gas filling (34). The mercury-free molecular discharge lamp further comprises discharge means (36) for maintaining a discharge (38) in the discharge space, and discharge-variation means (40, 42) for varying, in operation, a position of the discharge within the gas filling relative to each other, and/or for varying a dimension of the discharge within the gas filling over time. An effect of the varying of the position and/or dimension of the discharge over time is that at a specific variation-speed or variation-frequency the output power and/or luminous flux of the mercury-free molecular discharge lamp is substantially increased. This effect is found to be depending on the gas filling and on the variation-speed and/or variation-frequency.

Abstract: An optical sensor (600) for detecting the movement of an object relative to the position of the optical sensor (600), using self-mixing interference, is described. The optical sensor (600) comprises a laser (100), a detector (200) and a filter device (500). The filter device (500) suppresses measurement signals generated by means of the detector (200) when movements of the object at a velocity below a defined threshold value cause the measurement signals. The optical sensor (600) may be used in a switch in order to enable selective switching depending on the velocity of the movement of the object.
