An open mat system to reinforce turf includes an anchor arrangement to help secure the mat to the turf. A conductive grid structure is formed in the chip carrier and cap structure, the conductive structure having a plurality of meandering lines disposed in an x-direction, a y-direction, and a z-direction. A communication network communicates with the acquisition computer and with at least one additional computer. For each dye present in the specimen, a band of the illuminating light and a band of the detected light are calculated, the excitation and emission spectra read out from the database being employed. Where R1 and R2 are as defined above.
