Abstract
A method of imaging infrared light is provided which comprises: exciting ultrasonic waves in a metal pillar (e.g., Cu pillar); measuring the Time-of-Flight (ToF) of the ultrasonic wave in the waveguide; whereas the ToF is a function of incident Infrared light energy on the waveguide, and reporting the infrared light energy to capture an image. An apparatus of imaging infrared light is provided which comprises: a transducer; a waveguide coupled with the transducer; and a pixel electronic circuit coupled to the transducer, wherein the transducer includes one or more of: PZT, LiNb, AlN, or GaN.
