Abstract
According to one aspect, an optical apparatus for a light detecting and ranging (LiDAR) sensing system is provided. The optical apparatus can comprise an optical directing device; and a multi clad optical fiber, wherein said multi clad optical fiber comprises a core, at least one inner cladding, and an outer cladding. The core is arranged to receive optical rays transmitted from a light source of said sensing system and route said transmitted optical rays on an optical path leading to optical directing device. The optical directing device is configured both to direct said routed transmitted optical rays on an optical path leading to a target to be sensed and direct optical rays reflected from said target on an optical path leading to said inner cladding of said multi clad optical fiber. The inner cladding is configured to receive said reflected optical rays and route said reflected optical rays on an optical path leading to a detector for receiving reflected optical rays of said sensing system.
