1. A light reflection device, comprising:
a reflection member having a reflection surface that is formed in a planar shape to reflect incident light, the reflection member performing a revolution and a rotation simultaneously,
wherein a direction of the revolution of the reflection member and a direction of the rotation of the reflection member are the same, and
wherein angular velocity of the revolution of the reflection member is equal to twice angular velocity of the rotation of the reflection member.
