Paper Abstract

The signal from a laser range finder is greatly enhanced by attaching a retroreflector to the target. Low-cost, lightweight retroreflectors can be fabricated from conspicuity tape. This work reports the near-infrared retroreflection characteristics of conspicuity tape from bidirectional reflectance distribution function (BRDF) measurements at 904 nm. BRDF values approach 500 sr-1 at near normal incidence. The BRDF test results are applied to predict the performance of alternate lightweight retroreflector designs suitable for tracking small helium balloons. The combination of a range finder and retroreflecting balloon enable a low-cost, high-performance method for wind profiling.
