A process for recording pulse signals of at least two input channels includes sampling the input channels with a predetermined sampling frequency for events which have occurred, and after detection of an event in at least one of the input channels, or after overflow of a counter, storing the present state of all the input channels in a memory register together with a magnitude characterizing a time interval to the last storage operation. The device for recording pulse signals of at least two input channels according to the process includes a clock oscillator, a sampler that samples the input channels, a counter, and a memory. The detection of a first event in one of the input channels or the overflow of the counter, according to which event occurs first, triggers and operation of storage of the states of all the input channels and of the last counter state at the occurrence of the event.

Process for the recording of pulse signals

An optical arrangement includes several separate individual beams that pass through a common focus before a first segmented mirror field and, after reflection by respective separate mirrors of the segmented mirror field, the individual beams are imaged by an objective on one or more workpieces. A second segmented mirror field is arranged between the first segmented mirror field and the object, or at least one beam splitter is arranged after the focus and deflects the individual beams onto at least one segmented mirror field, by which they are reflected back at least nearly identically on themselves.
