Abstract

This paper describes tests of a novel detector electronics for a prototype optical pick-up designed to be used in a Hyper CD Drive with Terabyte storage capacity. A phase-sensitive detection was implemented using an RF quadrature demodulator receiver module (Analog Devices, AD607), which operates on the principle of superheterodyne coherent detection. The characteristics of this detector will be analyzed. The goal is to select an appropriate detector system for detecting a florescence laser pulse from recorded medium.
