- 1. A method for selecting a restricted set of N energy levels from a possible set of energy levels, comprising the following steps:
- selecting subset E.sub.j from the possible set of energy levels;
- marking for each selected energy level E.sub.j from said subset a plurality of identical spotlike zones, isolated from each other by a low density background, each zone comprising an internal zone of fixed high density marked by a stable energy level E.sub.s and a surrounding zone of density marked by said energy level E.sub.j ;
- measuring the reflectance R.sub.j integrated over said plurality of identical zones partially marked by energy levels E.sub.j ;
- dividing the range of measured reflectances R.sub.j in N-1 equally sized intervals (R.sub.k, R.sub.k +1);
- finding an energy level E.sub.k for each reflectance R.sub.k using the measured reflectances and energy levels (R.sub.j, E.sub.j); and
- defining the restricted set as being composed of the energy levels E.sub.k.
