Due to its good retroreflection ability, micro triangular pyramid has been widely used for reflex reflector. Both the working principles for micro triangular pyramid element and micro triangular pyramid array have been demonstrated. Besides, the theoretical expression of reflectivity for micro triangular pyramid array has been derived. The performance for the micro triangular pyramid array as a compound optical system has been simulated by the geometric optical software. Performances including reflective effect, reflectivity and reflective energy have been obtained. Both theoretical and simulation results have shown that effective reflection area of the reflex reflector has been enlarged, and the reflection efficiency is also enhanced.
