N2 - This paper examines amplitude and phase methods for extracting position information from the position sensitive detector (PSD). Comparison of performance levels of both detection methods is performed under the same conditions employing a new, high performance electronic detection circuit, and independent, high resolution, reference position sensing system, Resolution of distance measurements with the Position Sensitive Detector (PSD) is often limited by electronic circuit used for signal processing. Employing a high performance electronics based on the early stage photocurrent digitalization and high accuracy reference position sensing system [4], proper comparison of two different methods (amplitude and phase) for position measurements was made possible. Amplitude method is based on the first approximation of the equation of PSD mathematical model [2] and phase methods on second order approximation of the same equations [3,4].
