Abstract

A simple low-cost microdensitometer is described, based on a mirror stereoscope as it is used in aerial photographic interpretation. The eyepiece head is modified to take two photosensors whose light beams are reflected by a beam splitter while the other parts are passing the eyepieces. Variable apertures in front of the photosensors allow pointwise and surfacewise density measurements. The instrument is used for both near and remote sensing interpretations and measurements and for ground truth purposes of vegetation evaluations primarily for leaf physiological examinations, such as leaf surface changes.
