But while security applications remain the most valuable for the industry, 2015 is also expected to see substantial growth in the production of holographic optical elements (HOEs) for use in automotive displays and lighting, as well as for general lighting control, says Ian Lancaster, the general secretary of the International Hologram Manufacturers Association (IHMA).
“Anti-counterfeiting technologies will grow as the criminal masterminds get more sophisticated every year, and the security printing industry needs to expand capabilities using multiple technologies to remain ahead,” said Lancaster.
Product counterfeiting is a trillion dollar a year problem, which represents about 5 – 7% of all global transactions, so the long term outlook for anti-counterfeiting technologies is good.
“There will be growth in all markets but those countries with an emerging middle class will probably see the highest. This includes economies such as India where there’s continued expansion – and our industry in India will reflect this with growth of up to 20%,” said Lancaster.
The design of authentication solutions is advocated in ISO’s 12931 standard, to verify the authenticity of a legitimate product, differentiating it from the counterfeits.
Holograms can also be used to control light and the growth of LEDs is stimulating the adoption of holograms to provide better control of their emitted light.
HOEs are being used to diffuse and “smooth” the light from arrays of LEDs as now being used in display and domestic environments, while they are also being used to focus and shape the light.
Similarly, with LEDs in use as vehicle rear lights and brake lights HOEs are also being used to enhance the emitted light. Meanwhile, HOEs also have an important role in vehicle instrumentation and improving the image on small and large format LCD and OLED displays.
