Abstract

A method for photosensor signal processing includes carrying out, by measuring a combination of readout channels of a direction e with linearly increasing and linearly decreasing signal strength, a linear coding in at least one e-direction. The linearly increasing and linearly decreasing signal strengths of readout channels of the direction e, which are respectively used for the linear coding, are multiplied by each other. The linear coding satisfies the following edge condition: Q1(e)=c1·ec2+c3, Q2(e)=c4·ec5+c6, c1=const. ∈(0, ∞), c4=const. ∈(−∞, 0), c3, c6=const. ∈(−∞, ∞), and 0.5<c2; c5<1.5. Q1 denotes the charge of the output channel signal strengths increasing via the e-position, and Q2 denotes the charge of the output channel signal strengths decreasing via the e-position and the coding direction.
