Abstract
In recent times the importance of Ladar systems for military applications increases rapidly. Prevalent application in this area is 3D imaging. Conventional 3D scanning systems usually employ mirror-based mechanisms. Often these suffer from bulky architecture and a fixed scanning pattern. In this paper we describe an experimental monostatic Ladar setup with micro-optical bidirectional beam control. This system offers certain advantages like random beam pointing and a compact design due to transmissive optical elements with combined emitter and receiver channel. Our publication depicts the setup of a Ladar demonstrator with micro-optical beam steering at lab-level. The range finding system is based on time-of-flight principle at near infrared wavelength. Due to monostatic configuration a single detector is used for start and stop pulse generation. The beam steering is accomplished with decentred micro-lens arrays, which are driven by a precision alignment system. The micro-optical elements act as entrance and exit aperture simultaneously. The results of laboratory characterization measurements and data evaluations complete our overview of the accomplished work.
