DirectShear™ - Optical Sensors are robust, high-bandwidth shear stress sensors designed from the ground up for harsh environments, including high-temperature applications. The sensors employ purely optical transduction, a silicon/Pyrex micromachined floating element, and a remote optical fiber readout to enable time-resolved one-dimensional, direct shear stress measurements at high temperatures.
Like the original DirectShear line of sensors, IC²'s DirectShear Optical Sensors are capable of both mean and dynamic measurements of wall shear stress over a wide dynamic range and are offered in a range of sensor models to suit different applications.
The optical sensors are now commercially available and are ideal for precision skin friction measurements in high speed, and high temperature test facilities.
