摘要:
An optical display device has a set of LEDs arranged in a matrix and includes control circuitry which acts as a controllable current source and as controllable voltage sources. The control circuitry enables a constant current to be applied for each LED, and respective voltages to be established accordingly. Due to the additional logic circuitry which deliver different clock pulses at different frequencies for cyclic switching of at least one LED, signals that are visible to the human eye are generated and at the same time signals that are not visible to the human eye are also generated. The signals that are not visible are digitally coded and transmitted for appropriately adapted reading devices. Thus additional information for a variety of purposes can be made available, especially in the communications and traffic area, simultaneously with the lighting up of the LEDs. This refers in particular to traffic control systems, diagnosis and monitoring. An optical display device designed in this way permits a design, for example, as a taillight, brake light, flashing indicator light and the like in a motor vehicle or with other traffic and communications means and also in equipment in production facilities while permitting favorable production at the same time due to reduced fault in assembly and ease of adjustment of the light values.

A laser system includes a gain medium for providing and amplifying a laser beam within an optical resonator. According to the invention, the laser system actively provides a plurality of different optical modes for stabilizing the laser beam, preferably by forcing the laser beam to jump between different optical modes more frequent than environmental disturbances occur. Providing the plurality of different optical modes can be achieved e.g. by varying the phase of the laser beam and/or by varying the optical length of the optical resonator. The laser system can be employed in a gas monitoring system, e.g. for monitoring a respiration and/or anaesthetic gas, for providing a Raman spectrum of the gas to be monitored.
