The starting point of DLP Pico is a CMOS substrate on top of which is an array of anywhere between 250,000 to over two million individually and independently hinged micromirrors, each around 10 µm in size.
Each mirror can switch to one of two states: Light reflected from the DLP chip will either go into an active optical path or if the mirror is in the ‘off’ position, then light will be routed out of the optical path and absorbed
The idea of structured light is to project light on to an object, capture the reflection and then process the reflection to create a 3D point cloud representation of the object. This gives the user valuable shape information about the object in all three dimensions: x, y and z. Because the mirrors in the DLP chip are independently and individually controlled, it allows specific ‘structured’ patterns of light to be projected depending on the application need.
