THE ULTRACAM STORY

UltraCam Photogrammetric Digital Aerial Cameras

Multicolour observations of V404Cyg with ULTRACAM

We present high time-resolution multicolour observations of the quiescent soft Xray transient V404Cyg obtained with ULTRACAM . Superimposed on the secondary star’s ellipsoidal modulation are large flares on timescales of a few hours, as well as several distinct rapid flares on timescales of tens of mins. The rapid flares, most of which show further variability and unresolved peaks, cover shorte...

Radiometric Quality of Ultracam-x Images

The large digital frame camera UltraCamX was introduced in 2006 by Vexcel Imaging (a Microsoft Company). This paper will give a short technical overview about the concept of the camera and more information on the radiometric quality of the UltraCamX. The focus in this paper is set on the radiometric quality of the sensors. Already recorded image data are analyzed in detail for their radiometric...

Calibrating and Testing New Ultracam Sensors

This contribution reports on the latest design of new UltraCam sensors. We present results from calibration and verification flights of the UltraCam Condor, which is based on a specific design and offers highest productivity from its 38000 pixel cross track image format. UltraCam Condor is based on the successful project experience with its predecessor, the UltraCam G.

The Ultracam Large Format Aerial Digital Camera System

The race is on to introduce an aerial digital camera system to outperform the current aerial film cameras in quality, accuracy and economics. We introduce the UltraCam-D large format digital aerial camera. It achieves superiority over conventional aerial film imaging. The system produces aerial "photography" as if a film camera had taken film images that then were scanned. As a result, images t...
