Laser-based projector for mobile use is size of a matchbox

8 March 2006 News

Cambridge-based Light Blue Optics has developed unique laser-based projection technology, which uses computational algorithms and novel optical techniques to allow miniature lasers to display video images in realtime using the diffractive nature of laser light.

The company developed the innovative PVPro technology for miniature projectors, which can be used to display images from a range of mobile devices, including laptop computers, personal media players, digital cameras and even mobile phones. This overcomes the size limitation of conventional projection techniques, allowing projectors to be significantly smaller than was previously possible.

Light Blue Optics (www.lightblueoptics.com) is now offering a matchbox-sized demonstrator unit, which is only 62cc in volume. The latest monochrome 'micro-mini' version represents the third generation of the PVPro algorithms and optomechanical design.

The advantage of the Light Blue Optics approach is to address the four key requirements for a small battery-powered device. These are compact size, low power consumption, which allows the projector to be battery-powered, ease of use due to the focus-free operation of the system, and robustness both physically and in terms of error-tolerance.

The evaluation kit includes a demonstration projector unit, appropriate PC software, technical documentation and support.
