Structured light by diffractive optical elements for

motion sensing and gesture recognition systems

For Infrared laser based human body motion sensing and gesture recognition systems, diffractive optical elements (DOEs) are without doubt an ideal solution. This is because DOEs can convert a laser beam to virtually arbitrary intensity distribution (typically structured light) that matches the requirements of customers very well. In addition to human body motion sensing and gesture recognition systems, it can be actually used for tracking the movement of many other things. They are also used for 3D mapping, shape measurements, machine vision, computer vision and vision for smart mobile devices. 

The following pictures show a customer's desired structured light pattern and the actual pattern generated by our designed and fabricated DOE. It can be seen that the two patterns are in excellent agreement with each other.
