Light Blue Optics (LBO), a startup in
Cambridge, UK, recently secured another
$15 million in funding for its holographic
laser projection technology. With its system, a diffraction pattern of the desired
2-D image is calculated using patented
holographic algorithms, then shown on an
LCoS microdisplay. When illuminated by
coherent laser light, the desired 2-D image
is projected. Three techniques, two proprietary, are used to remove speckle and improve the image.
LBO’s “cool” factor lies in its ability to
turn the projected image into a touch
screen via an infrared beam – invisible to
the eye, superimposed over the projected
image – and a sensor that detects when
and where the image is touched.
LBO announced in June that its first
product will be released to OEM customers in the fourth quarter of 2009.

as mobile projectors, head-up displays and
rear-projection TVs. The € 16.2 million program, a consortium of 23 companies and
research institutions, began in 2006 with
€ 9. 7 million in European Union funding.
It is scheduled to end in January 2010.
Over the course of the project, Brighter
announced a series of firsts in lab-based
records for red, infrared and green lasers.
In the coming months, the red and green
laser modules will be tested for display
application feasibility. The goal is to create devices featuring the technology over
the next two to five years.
Late last year TI began selling a DLP
Pico projector development kit, called DLP
Discovery, that allows developers to incorporate DLP into emerging applications.
“The open source community is using
the Pico kit in a variety of interesting
ways: for example, 3-D optical measurement systems and augmented reality overlay of information,” said Arun Chhabra,
business development manager of DLP
Embedded at TI. Based on feedback from
developers, he said, “We plan to introduce
kits that are targeted at more specific application areas” to accelerate experimenta-tion-to-development time.
“Stay tuned over the next six months
for exciting developments on this front,”
Microvision also is working with OEMs
to design products that embed its PicoP,
which is about the size of an Andes chocolate mint. Those products might be introduced in 2010 or 2011, Nichols said.
