Light Blue touchpaper is lit

An electronics start-up developing pocket-sized laser projectors has received Government cash to build a prototype.


Light Blue Optics in Cambridge has been awarded a £75k R&D grant from the DTI to develop a full-colour version of the monochrome projector it unveiled in February of last year. The next-generation unit will use three miniature lasers to display full colour video images.

The company is now in growth mode and is planning to expand its engineering team. It is looking for hardware development and optical engineers.

The technology is currently matchbox sized but the company says it will be able to reduce the size significantly in order to incorporate it into a range of mobile devices.

Light Blue said future products would range from truly pocket-sized miniature projector accessories for iPods, phones, and other mobile devices, to a wide array of consumer electronics products with integrated projection capabilities.

The key advantages of Light Blue’s technology, according to the company, are its size, energy efficiency and robustness. The system, which it calls CGH or computer generated holograms, is also easy to use as the image is always in focus regardless of the distance from the projector, even on curved surfaces.

The company is based at St John’s Innovation Centre in Cambridge.
