High-Bandwidth Photodetector for Missile Applications

This program will develop a self-contained large optical active area high-gain sensor appropriate for LADAR and range finding applications. Intevac's existing technology for IPD sensors meets the performance requirements for such applications. Theproposed sensor optimizes packaging by integrating the high-voltage power supply and output amplification stages into a single compact and rugged sensor unit targeted for 532nm wavelength applications. Program tasks include (i) redesign of the sensor tubecomponent to reduce its size while providing an 8mm diameter optical active area; (ii) integration of an appropriate high-voltage bias supply so that only 24VDC power is required to operate the sensor; and (iii) integration of an appropriate amplificationcircuit to provide a properly conditioned high-gain low-noise sensor output.
