Leica Geosystemsannounced the ADS40 2nd Generation Airborne Digital Sensor and the SH51 and SH52 sensor heads. The SH51 is equipped with new beamsplitter technology that provides panchromatic images for stereo viewing and the SH52 adds stereo color-infrared capability. The guiding single-lens design for the ADS40 2nd Generation avoids multiple-lens image patching.
