TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
One preferred approach to directly image an exoplanet is to build a space-based telescope instrumented with advanced internal coronagraphs, where deformable mirrors (DMs) with high actuator counts are essential for achieving very high contrast detection. When actuator quantities are in thousands, the electrical driver poses a fascinating challenge for space-based applications, where power and mass are limited, and reliability is extremely important for the mission life-time in space. What proposed is a 64x64 channels of monolithic multiplexed driver, which can deliver voltages up to 300 V to all the actuators at different time slots. Thus the required operation power is greatly reduced. By vertically integrating the application specific integrated circuit (ASIC) driver with a DM, the potential wiring failure will be eliminated. Furthermore, radiation resistance will be emphasized during ASIC design.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The proposed ASIC driver is specifically designed to drive the stacked DMs that NASA has been qualified in ground. It will provide a reliable, low power, monolithic DM driver that can be used by an exoplanet-imaging coronagraph. Thus it will be found valuable in applications on those missions, such as WFIRST and ATLAST, where coronagraphic instruments are required.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The first beneficiaries of the ASIC driver are the DM manufacturers. With a vertically integrated ASIC driver, the fabrication of a DM will be dramatically simplified since thousands of wiring will no longer be required. Thus, the yield and reliability will be greatly improved. Furthermore, with a simplified architecture, DMs with tens of thousands of actuators will become possible at affordable prices, which could attract more AO applications such as retinal imaging, fidelity microscopy imaging and laser drilling.

TECHNOLOGY TAXONOMY MAPPING (NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.)
