Notes Relating to the Design of a High Quality Image Sensor (opens in new tab)

Notes Relating to the Design of a High Quality Image Sensor Horn, Berthold K.P. Some of the information that as used in arriving at a design for a high quality image input device is documented. The device uses a PIN photo-diode directly coupled to an FET-input op-amp as the sensor and two moving-iron galvanometer-driven mirrors as the deflection system. The disadvantages of a system like this are its long random access time (about 4 milli-seconds) and the long settling time of the diode-ampli...
