TY - JOUR AU - Ludwikowski, Krzysztof AB - The rapid progress of light emitting diode (LED) technology has recently resulted in the availability of high powerdevices with unprecedented light emission intensities comparable to those of visible laser light sources. On this basis twoversatile devices have been developed, constructed and tested.The first one is a high-power, single-LED illuminator equipped with exchangeable projection lenses providinga homogenous light spot of defined diameter. The second device is a multi-LED illuminator array consisting of a numberof high-power LEDs, each integrated with a separate collimating lens. These devices can emit R, G, CG, B, UV or whitelight and can be operated in pulsed or continuous wave (CW) mode. Using an external trigger signal they can be easilysynchronized with cameras or other devices. The mode of operation and all parameters can be controlled by software.Various experiments have shown that these devices have become a versatile and competitive alternative to laser andxenon lamp based light sources.The principle, design, achieved performances and application examples are given in this paper.
