Space Vehicle Inspection High Range Resolution & Raman Spectral LIDAR, Phase II

Completed Technology Project

Project Introduction

As a result of an extremely productive Phase I program, SPEC has designed and built a pre-prototype of a 1.5 U CubeSat format LIDAR, with class 1 eye-safe lasers for space structure inspection applications. The Space Vehicle Inspection High Range Resolution, Raman Spectral LIDAR provides both Raman Spectra for determination of the surface chemical content and precision imaging consisting of high range accuracy 3D LIDAR and RGB camera images fused to give an HD resolution image. Range accuracy for the high range accuracy 3D LIDAR is 15 microns out to a range of 6 meters. This capability is achieved by adapting a SPEC part inspection LIDAR with the high framing long range SPEC LIDARs. The chemical detection capability can interrogate a molecule one layer thick adsorbed on the surface determining chemical content and allowing detection of leaks or contamination in pressurized or vacuum conditions. The LIDAR provides both ultra, high resolution imaging of surface imperfections and holes caused by micro meteor or debris, and the chemical content map of the 3D imaged area. Maximum range for the Raman LIDAR is 300m at 3mm resolution and 6 meters at 15micron resolution. More »
