Tiny 3D-printed cameras to change medical imaging and surveillance
Current lenses are restricted by their size, shape and dimensions thanks to manufacturing methods. Many times, multiple lenses and out-of-the-ordinary shapes are required for high optical performance.
To overcome this challenge, the team developed 3D printed micro- and nano-optics with complex lens designs that were manufactured with femtosecond two-photon direct laser writing.
The new method provides an enormous amount of flexibility andpaves the way for miniature printed cameras that include instruments such as endoscopes, fiber-imaging systems for cell
biology,illumination systems, miniature optical fiber traps, integrated quantum emitters and detectors, and even miniature drones and robots with autonomous vision.
According to Phys.org, “the imaging system fits comfortably inside a standard syringe needle, said the team, allowing for delivery into a human organ, or even the brain.”
The entire discovery is made possible as a result of 3D printing, which enables new production possibilities.
Their discovery makes possible the ability to conduct imaging on the micrometer scale. The team even insinuates that imaging systems the size of a grain of salt can soon be possible as a result of the technology and lead to a variety of devices that will impact biotechnology and security.
