Abstract: Provided is an image laser radar optical system with inscribed light transceiving modules. The image laser radar optical system includes a zoom lens type light transmitting module (10) which receives an emitted laser beam (A) having an inherent numerical aperture of a light source, and converts the emitted laser beam (A) into a transmitting laser beam (a) having a constant light divergence angle to emit the transmitting laser beam to an object (T) at a given distance, wherein the constant light divergent angle of the transmitting laser beam (a) varies depending upon the numerical aperture. Therefore, the size of the laser beam can be obtained corresponding to the intention of a user even though various kinds of laser beams having different numerical apertures are used. In particular, since an optical axis of the laser beam emitted from an object lens (15) of the zoom lens type light transmitting module (10) coincides with an optical axis of the laser beam received by a receiving object lens (31) of a light receiving module (20), an area overlapped by each other is minimized, and the size of a scanner (200), which is additionally equipped in the module, is also minimized.

Abstract: 본 발명의 내접형 송수광모듈을 구비한 영상 레이저 레이더 광학계에는 고유한 광원의 수치구경(Numerical Aperture)을 갖는 출사레이저(A)가 들어오고, 상기 출사레이저(A)를 일정한 광 발산각을 갖는 송광 레이저(a)로 변환하여 일정 거리의 피사체(T)에 출사하며, 상기 송광 레이저(a)의 일정한 광 발산각은 상기 수치구경(Numerical Aperture)에 맞춰 변화되는 줌 렌즈형 송광 모듈(10)이 포함됨으로써, 각각 다른 수치구경(Numerical Aperture)의 다양한 레이저의 종류가 사용되더라도 레이저의 광선 크기가 사용자의 의도에 맞게 항상 획득될 수 있고, 특히 줌 렌즈형 송광 모듈(10)의 송광 대물렌즈(15)에서 발산되는 레이저 광축과 수광 모듈(20)의 수광 대물렌즈(31)로 수광되는 레이저광축이 일치함으로써 서로 간에 가려지는 면적이 최소화 되고, 함께 구성되는 스캐너(200)의 크기도 최소화되는 특징을 갖는다.

Abstract: The present invention relates to a laser-radar optical system which includes: a transmission unit for emitting a transmission signal to a target in the front through a plurality of light-emitting lasers; an objective lens for refracting and focusing a reflection signal reflected from the target; a receiving optical fiber bundle cable for receiving the focused reflection signal through the objective lens and making the signal into single signal; a scaling optical system which is formed in one side of the receiving optical fiber bundle cable for reducing the intensity of the reflection signal emitted from the receiving optical fiber bundle cable; and a single detector for receiving the reflection signal with reduced intensity emitted through the scaling optical system. A laser-radar optical system for receiving spatially-separated multiplexed signal with a single detector which is capable of realizing a small-sized transmission and reception optical system is provided by using the transmission optical fiber bundle connector, receiving optical fiber bundle connector, scaling optical system and single detector.
