- 입방체 역반사 소자들로 구성되는 역반사체에 있어서, 적어도 입방체 역반사 소자 2개가 180°회전되어 맞대어 쌍을 이루고, 쌍을 이루는 각 역반사 소자가 공동면에 놓인 직선 모서리에 의해 밑면이 정의되는 상호 수직인 측면 3개와, 소자의 한 모서리쪽으로 기울어진 시각축을 갖도록 해서, 기울어진 쪽의 상기 모서리와 상기 공동면에 대해 수직인 X-축면과 X-축과 공동면에 대해 수직인 Y-축면 두면에서 역반사체의 역반사 각도를 증가시킨 것을 특징으로 하는 역반사체.
- 제1항에 있어서, 입방체 역반사 소자들은 반사표시값이 1.5인 물질을 구비하고, 소자들의 시각축이 측면의 밑 모서리들이 놓인 상기 공동면에 대해 수직인 위치로부터 약 7 내지 13도의 기울어진 것을 특징으로 하는 역반사체.
- 제2항에 있어서, 입방체 역반사 소자들은 반사표값이 1.5인 물질을 구비하고, 소자들의 시각축이 상기 공동면에 수직인 위치로부터 8 내지 9.736도 기울어진 것을 특징으로 하는 역반사체.
- 제1항, 제2항 또는 제3항에 있어서, 입방체 역반사 소자들의 시각축들이 동일면상에서 놓이는 것을 특징으로 하는 역반사체.
- 제1항, 제2항 또는 제3항에 있어서, 넓은 영역에 입방체 소자들의 밀집배열을 갖는 중합 시이트 물질로 구성되는 유연한 역반사 시이팅 형태에 공통 깊이와 V자형 단부를 갖는 3세트의 교차하는 연속 홈들로 소자들의 상호 수직인 측면 3개를 형성해서 공동면에 놓인 측면의 밑 모서리가 홈의 밑부분에 의해 만들어지고, 적어도 상기 소자들의 그 일부가 제1항 내지 제4항중 어느 한 항에서 설명한 쌍으로 배열되는 것을 특징으로 하는 역반사체.
- 제4항에 있어서, 넓은 영역에 입방체 소자들의 밀집배열을 갖는 중합 시이트 물질로 구성되는 유연한 역반사 시이팅 형태에 공통깊이와 V자형 단부를 갖는 3세트의 교차하는 연속 홈들로 소자들의 상호 수직인 측면 3개를 형성해서 공동면에 놓인 측면의 밑모서리가 홈의 밑부분에 의해 만들어지고, 적어도 상기 소자들의 그 일부가 제1항 내지 제4항중 어느 한 항에서 설명한 쌍으로 배열되는 것을 특징으로 하는 역반사체.
