2-D Optical Preamplifier Pixel Arrays For Near Photon-Counting FLASH LADAR Receivers

Aerius Photonics proposes a 2-D Optical-Preamplifier Pixel Array (OPPA) to provide near photon-counting imaging FLASH LADAR receiver sensitivity with linear-mode operation, full pulse shape discrimination, superior countermeasure immunity, and distinct advantages that improve target discrimination. The approach leverages single pixel receiver programs underway at Aerius. Aerius’ OPPA is an optical-preamplifier pass-through approach that is system compatible with advanced direct-detection and coherent Ladar receiver technology programs underdevelopment by the DoD. The OPPA receiver offers an input referred noise equivalent power of 2.4 photons and can achieve an SNR of 10 with 7.5 received photons. The OPPA operates at room temperature, utilizes mature PIN detector array technology, and enables system performance improvements while reducing system cost, weight, and power. Phase II will deliver a 1064 nm 128x128 FLASH Ladar receiver that utilizes Aerius' pixel amplifier technology. In Phase I, Aerius will demonstrate the concept feasibility with the fabrication and test of a 4x4 array of pixel amplifiers operating at 1064 nm and develop a system architecture design for integration with our technology partner’s receivers and systems in phase II.
