Abstract:
1. An apparatus for irradiating a plurality of selected regions of a target material in order to excite members of an excitable species contained within said selected regions to a particular state of excitation, said apparatus having a plane of focus and comprising: a first source of radiation for generating a first radiation adapted to excite said members to said particular state of excitation; means for directing said first radiation to said plurality of selected regions; a second source of radiation for generating a second radiation adapted to reduce the ratio of excited members in said particular state of excitation to members not in said particular state of excitation at said selected regions; means for directing said second radiation to said regions, so that said second radiation has a minimum portion in each of said regions and means for measuring the radiation emitted from said plurality of selected regions so that radiation from at least two of said plurality of regions is measured simultaneously.
