A 3D Camera For Safer Autonomy And Advanced Biomedical Imaging

The creation of 3-D images and range detection has been proven by researchers using stacked, transparent graphene photodetectors in conjunction with image processing methods. The feasibility of a 3D camera that can deliver superior three-dimensional imaging while calculating how far things are from the lens has been established by researchers. Robotics, autonomous vehicles, and 3-D biological imaging depend on this knowledge.

The proposed camera uses a stack of transparent graphene photodetectors instead of the opaque ones typically used in cameras to concurrently capture and focus on objects at various distances from the lens.

The peculiar properties of graphene, which is only one thick atomic layer and only captures about 2.3% of the light, make the system function. Even though less than 5% of the light is consumed, it is possible to create a photodetector that is effective at detecting light using two graphene layers. The detectors can be stacked, each in a separate focal plane, and mounted on a transparent substrate rather than a silicon chip.

According to researchers, to focus on a specific object, such as a person’s face, you need to change the focus on your camera’s lens so that the light rays coming from that object are concentrated onto a single plane on your detector chip. Out of focus are objects in front of or behind the item.
