In the later years, laser has become the new light source generation of projection technology. Laser illumination provides a wide colour spectrum, long lifetime of lasers, low cost and much lower power consumption due to high electrical to optical efficiency of laser sources.
However, the laser display projection has a disadvantage of introducing speckle by scattering and interference of coherent laser beam from a diffuse surface.
-The objective of our project is to develop next generation high-end picture projector technology platform based on red-green-blue laser sources, digital-micro-mirror device (DMD) display chip and de-speckle module, she explains.
Research will be done to develop methods and solutions for speckle reduction using Silicon micro-electro-mechanical system technology and other device concepts which can bring down speckle to below human perception limit.
Detailed experiments will be done using developed prototypes, and visual psycho-physics measurements will be performed to determine human speckle perception limits.
