Abstract

Retroreflection, which is also known as the cat-eye effect, occurs in many imaging systems. The laser beam that irradiates on the focused photodetector would be reflected along its entranceway, by means of which the focused imaging system could be easily discovered and located. The paper analyzes the present research status of retroreflection reduction techniques. It shows that the related techniques mainly focus on four aspects: defocusing, masking, filtering, and one-way optical device. However, there are still some apparent disadvantages among the above technical schemes, which are generally manifested in the severe loss of imaging quality and the restricted application scope. Along with the rapid development of parallel computing platforms in recent years, computational imaging is widely applied in many fields. The paper proposes two novel configurations of anti-laser reconnaissance imaging systems based on the wavefront coding and the light-field rendering. Applying the computational imaging techniques will hopefully achieve a substantial retroreflection reduction without severely degrading the imaging quality, which shows us a broad prospect.
