Abstract

Three sensor designs for full field laser doppler blood flow imaging will be demonstrated(i) 16x1 pixel linear array with mixed analogue and digital signal processing (ii) 4x4 pixel array with all analogue processing (iii) hybrid system which combines 32x32 pixel array with part on-chip processing linked to a field programmable gate array. Results are demonstrated using modulated light, tissue phantoms and blood flow in tissue. The efficient use of silicon when implementing the signal processing on-chip is discussed.
