Method for the signal processing of a photosensor

A method for photosensor signal processing, the method comprising:

• 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,
• wherein 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,
• wherein the linear coding satisfies the edge condition:
• Q1(e)=c1·ec2+c3
• Q2(e)=c4·ec5+c6
• c1=const.∈(0,∞)
• c4=const.∈(−∞,0)
• c3,c6=const.∈(−∞,∞)
• 0.5<c2;c5<1.5,
• wherein 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, and
• wherein the depth of interaction is approximated using:
