On this 20th day of Black History Month, we proudly recognize Valerie L. Thomas (born 1943) — a pioneering NASA scientist, physicist, and inventor whose groundbreaking work helped shape modern imaging technology.
A physicist by training, Thomas played a vital role at NASA, where she managed image-processing systems for the Landsat program, helping enable some of the first satellite images of Earth from space. Her leadership contributed to advancements in how we view and understand our planet from orbit.
The Illusion Transmitter & Early 3D Imaging
In 1977, Thomas began developing what would become her most celebrated invention — the illusion transmitter.
In 1980, she received a patent for this innovative device, which uses concave mirrors and carefully directed light rays on both the transmitting and receiving ends to produce three-dimensional optical illusion images.
Her invention became an early foundation for 3D imaging technology. By demonstrating how three-dimensional visuals could be transmitted and reconstructed with depth and realism, Thomas expanded the possibilities of scientific visualization.
Today, elements of this technology continue to influence advancements in:
- Medical imaging tools used by surgeons
- Space science visualization systems
- Advanced display and screen technologies
Her brilliance helped open doors to a future where we can see — and understand — complex images in entirely new dimensions.
A Lasting Legacy
Valerie L. Thomas’s work reminds us that innovation has no limits. Through her dedication, intelligence, and perseverance, she helped transform imaging science and expand what humanity can visualize — from Earth’s surface to the vastness of space.
👏🏾 Shout out to Valerie L. Thomas — a true innovator whose work helps us see the world, and beyond, in a whole new dimension.
Thank you for your groundbreaking contributions. Your legacy continues to inspire generations of scientists, inventors, and dreamers.
