ABSTRACT:
Disclosed is a pyroelectric shear meter which can be utilized as a pyroelectric vorticimeter in which a pyroelectric substrate has a heater element located thereon and two conductor elements located adjacent the heater element. The conductor elements are spaced apart along the longitudinal axis of the heater element and located on the same side of the longitudinal axis. A fluctuating power supply is connected to the heater element causing a fluctuating surface charge distribution which varies as a function of the temperature of the substrate in the vicinity of each of the spaced apart conductor elements. Differences in charge redistributions sensed at each of the spaced apart conductor elements is an indication of the differences in flow velocity due to shear in the vicinity of the shear meter. The orienting of two shear meters with heating elements at 90.degree. with respect to each other provides shear flow components in the X and Y directions and electrically multiplying the two shear flow components provides an electronic indication of the vorticity of the flow in the region of the pyroelectric substrate.
