    Notes: Market needs for airborne and spaceborne imagery used in photogrammetry and GIS applications are changing. Fundamental changes in sensors, platforms and applications are currently taking place. Most recently, new high resolution spaceborne sensors have become available. Besides classical photogrammetry, new thematic applications will drive the future image market. Savings in cost and time, together with the need for higher and reproducible radiometric resolution or spectral information will push forward the change from analogue to digital imagery. High resolution satellites will compete with airborne film-based photography and digital camera systems.With the availability of a digital airborne camera, it is possible to completely close the digital chain from image acquisition to exploitation and data distribution. The key decision regarding the camera design in this case is whether a linear or area array sensor should be used. In view of the high geometric accuracy requirements in photogrammetry, Z/I Imaging has focused development on a digital camera based on an area sensor. An essential aspect of this decision was not only the aerial camera system, but also the entire photogrammetric process to the finished photographic or mapping product. If this point of view is adopted, it becomes clear that the development of a digital camera involves more than simply exchanging film for silicon. Aspects such as data transfer rates, in-flight data processing and storage, image archiving, georeferencing, colour fusion, calibration and preprocessing have the same influence on the economic assessment of a digital camera system. This paper describes current development activities and application aspects of a digital modular airborne camera system.

    Description / Table of Contents: Zusammenfassung Der Turm von Hanoi (TH) mitm+3 Stangen undn Scheiben ist ein hundert Jahre altes mathematisches Spiel, das augenblicklich eine bemerkenswerte Wiederbelebung in der Informatik erfährt, wo es z. B. im Zusammenhang mit Produktionsplänen und Materialverwaltung diskutiert worden ist. Er wird üblicherweise durch doppelte Rekursion überm undn gelöst. In dieser Arbeit wird eine Lösung gleicher Länge vorgestellt, die rekursiv inm, aber iterativ inn ist und so zu einem rein iterativen Algorithmus für den Vier-Stangen-TH führt, aufbauend auf den wohlbekannten iterativen Lösungen des klassischen Drei-Stangen-TH. Diese Algorithmen hatten sich in Untersuchungen über Komplexitätsabschätzungen als viel leistungsfähiger erwiesen als die rekursiven und könnten von Interesse bei problemen des Sortierens angeordneter Befehle in Parallelrechnern sein. Einige mathematische Hilfsmittel werden hergeleitet oder aus der Literatur zitiert, um die Korrektheit des Algorithmus beweisen zu können.
    Notes: Abstract The Tower of Hanoi (TH) withm+3 pegs andn discs is a one hundred years old mathematical puzzle which is now experiencing a remarkable revival in computer science, where it has been discussed e.g. in connection with production scheduling and material handling. It is usually solved by double recursion onm andn. In this paper, a solution with the same length is provided which is recursive inm, but iterative inn, thus leading to a purely iterative algorithm for the four pegs TH, based on the well-known iterative solutions of the classical three pegs TH. These algorithms had turned out to be much more efficient than the recursive ones in studies of performance evaluations and might be of some interest in problems of sorting ordered instructions in a parallel computer. Some mathematical tools are derived or cited from literature in order to prove correctness of the algorithm.

    Notes: Abstract We describe a mid-infrared Laser Magnetic Resonance (LMR) spectrometer which is based on a cryomagnet and a sealed-off CO-laser. Faraday rotation combined with a multireflection cell is used for polarization sensitive detection of molecular radical ions. Experimental details and first spectroscopic examples are given.

    Notes: Abstract Frequency stabilization of the CO laser using a CO lamb-dip is achieved in the range from 5.0–6.3 μm. The CO saturation signal is obtained from a low-pressure discharge in absorption and is detected using optogalvanic, detection. The frequency stability and reproducibility has been verified to be better than 100 kHz; this is an improvement of more than one order of magnitude compared with locking techniques using CO laser gain profiles.

    Notes: Abstract Heterodyne frequency measurements have been made on the 12°0-00°0 band of carbonyl sulfide in the wavenumber range from 1866 to 1915 cm−1. Frequency measurement techniques reported earlier are used to measure the OCS absorption lines by means of a tunable diode laser, a CO laser local oscillator, and two CO2 lasers used as secondary frequency standards. A table of calculated absorption frequencies is given for OCS from 1866 to 1919 cm−1.
