SEOUL, Aug. 24 (Korea Bizwire) — The Korea Advanced Institute of Science and Technology (KAIST) said Wednesday that its research team has developed a holographic camera capable of acquiring 3D information by integrating a mask with existing cameras.
Holography involves generating 3D information by exploiting the interference phenomenon arising from the intersection of waves emitted by multiple light sources.
Due to the complexity of the interferometer device requirement and its susceptibility to the surrounding environment, holography technology remains at a pre-commercialization stage.
To overcome this challenge, the research team developed holographic camera technology by inserting a mask between the lens and the sensor.
This enables controlled light penetration in a specific pattern, and the captured information is subsequently reformatted using an algorithm, eliminating the need for an interferometer.
Cameras employing these masks for holography can even refine the focus post photo-capture by leveraging the object’s spatial data.
Consequently, even when photographs are taken with an initial misalignment of focus, users can attain clear images through subsequent corrections. This is particularly valuable when photographing objects such as coins and dice.
The camera can produce crisp photos of swiftly moving objects, effectively avoiding motion blur and other image anomalies.
