    National Institute of Standards and Technology fingerprint sensor resolution test pattern
    ( a ) Equivalent circuit model for receiving. ( b ) Pulse-echo images. Top: National Institute of Standards and Technology <t>fingerprint</t> resolution test composed of converging parallel lines. Bottom: axial resolution demonstration using two overlaid patterns separated by 127 μm in depth. ( c ) Ultrasound fingerprint image collected at the epidermis and sub-epidermis layer (top). Good agreement is observed between the ultrasonic images and the optical fingerprint image.

    Article Snippet: each experiment, pulse-echo measurements are collected from each of the 110 columns in sequence, with a complete image formed in 2.6 ms. .. In each column’s TX cycle, five adjacent columns ( N −2, N −1, N , N +1, N +2) of 56 PMUTs are excited without beamforming, and the center column ( N ) is used as receivers. shows a 2D pulse-echo ultrasonic image of a fingerprint sensor resolution test pattern fabricated by the National Institute of Standards and Technology (NIST; ), demonstrating a 5:1 contrast ratio over the 4.6 mm×3.2 mm ultrasound image. .. A separate test characterized the lateral resolution to be 80 μm, consistent with the 80 μm beam width computed using the acoustic model.
