Abstract
In order to make projector compact and efficient, we propose that the 2D laser source
module is consisted of VCSEL array and micro-lens array. It describes packaging structure design
of VCSEL array and thermal resistance calculation. A thermal 3D analysis of 3
$\times$
3 array based on the finite-element method (FEM) is presented. The analysis shows
that the maximum internal temperature of a VCSEL array reaches 51
$^{\circ}{{C}}$
. Then, it describes the principle of the micro-lens array. By ZEMAX simulation,
in the micro-lens array illumination system, we have got the energy efficiency 67.3%, the light
uniformity is 95.5%, respectively, on the micro-display chip at the distance of 65 mm. We have
successfully built the complete 3-LCOS projection system based on the 2D source module. It can
provide 1362 lm D65 light, and its total volume is
${{260}}\times {{200}}\times {{160}}\ {{mm}}^{3}$
which is more compact than the commercial projector.
