PRISM AND OPTICAL DETECTION SYSTEM APPLYING SAME

摘要

A prism and an optical detection system applying the same. The prism (223) comprises a lower plane (223a), an upper plane (223b), a first side surface (223c) and a second side surface (223d), wherein the first side surface (223c) and the second side surface (223d) are located between the upper plane (223b) and the lower plane (223a), and the first side surface (223c) and the second side surface (223d) are one-dimensional parabolic curved surfaces; the lower plane (223a) is used for receiving a light ray; the first side surface (223c) is used for reflecting the light ray from the lower plane (223a) to the upper plane (223b); and the second side surface (223d) is used for reflecting the light ray from the upper plane (223b) to the lower plane (223a), and then carrying out subsequent processing on the light ray.
