Let‘s talk about light
The use of dynamic diffractive optical elements offers more flexibility in optical microscope design. Special modulators with liquid crystal pixel structure enable three-dimensional focus configurations and optimal use of laser power.
Today, microscopy is possible even with modern smartphones using integrated optic modules and adapted smartphone camera optics. Such systems offer sufficiently high-resolution microscopy to detect single-cell parasites, leukocytes and erythrocytes, and are particularly useful in geographic regions with less developed clinical infrastructures.
With light we can look inside the body to see tiny cells and outside to see the stars in the universe. One special high-power laser system supports the use of adaptive optics for astronomical observations. The underlying principle could also be useful for quantum optics and atomic physics.
