Public award description
HIGH-SPEED SCANNING INTERFEROMETER USING CMOS IMAGE SENSOR AND FPGA BASED ON MULTI-FREQUENCY PHASE-TRACKING DETECTION IN THIS SBIR, WE PROPOSE A NEW TYPE OF LASER INTERFEROMETER ENGINE FOR IN-SITU LARGE OPTICS INSPECTION AND METROLOGY AND SUPPORTING SYSTEM PLATFORM. THE PROPOSED FPGA SIGNAL PROCESSING CONCEPT TOGETHER WITH NEW GENERATION HIGH-SPEED CMOS IMAGE SENSOR ENABLES HIGH SPEED (> 1M/SEC) AND REAL-TIME CONTINUOUS SURFACE PROFILING WITH MINIMUM LOCAL MEMORY. THIS TRANSFORMS THE CURRENTLY AVAILABLE LASER INTERFEROMETER INTO A SUB-NANOMETER PRECISION INSTRUMENT WITH ONLY MINOR MODIFICATION WHILE PROVIDING EASY SCALABILITY FOR LARGE OPTIC SURFACE TESTING AND MEASUREMENT CAPABILITY SIMULTANEOUSLY.
