Michał NawrockiResearchers at the Tokyo University of Agriculture and Technology have made a significant leap in microscopy technology with the creation of a portable holographic microscope that can be operated via a smartphone. Traditional digital holographic microscopes are often limited by their need for bulky desktop computers, making them impractical for fieldwork.
Yuki Nagahama and her team sought to change that by designing a compact device that is both affordable and versatile, suitable for various environments. The new microscope system utilizes a method called band-limited double-step Fresnel diffraction to minimize the amount of data required for operation, making it more efficient.
To complement the optical components, the researchers employed 3D printing technology to create a lightweight housing. An accompanying Android app has been developed to facilitate the hologram reconstruction process, allowing users to visualize samples in real-time on their smartphones.
This innovative tool can produce detailed images of microscopic samples, such as a cross-section of a pine needle, enhancing the user experience through touchscreen zoom functions.
The inspiration behind this advancement came from Nagahama’s experiences as a student working on portable microscopes, which led her to explore the capabilities of smartphones in scientific applications.
With potential uses in fields ranging from medicine to education, this groundbreaking technology can support a variety of important tasks, like diagnosing diseases or examining live microorganisms.
