Pitch

Pitch is typically taken to be the geometrical pitch of wires or strips in a planar detector, defined as the orthogonal distance between the centre of two adjacent parallel detector elements (the repetition unit). The spatial resolution of such a (one-dimensional) detector is determined by the pitch p:  ;

The readout of the signal in a microstrip detector is often done by grouping several strips; the distance between two readout channels is then called the readout pitch . The readout pitch  is an integer multiple of the geometrical pitch p; the spatial resolution of a microstrip detector would then be  ; readout by charge division, however, can improve substantially the achievable accuracy (see Bates93, Dabrowski96).
