MTFtest

The Modulation Transfer Function (MTF) is a valuable tool for manufacturers to assess the imaging capabilities of lenses and ensure they meet the desired standards for resolution and contrast. By analyzing the MTF curve, engineers can gain insights into the limitations and performance characteristics of a lens assembly.

Modulation Transfer Function (MTF) is commonly used to qualify and evaluate the performance of imaging systems, such as lens assemblies. MTF is a useful tool for measuring and characterizing the resolution and contrast of a lens, which are key factors in determining its overall quality. The MTF curve of a lens assembly shows the degree to which the system can transfer contrast from the object to the image plane at different spatial frequencies. The MTF curve provides information about the lens' resolving power, or its ability to distinguish fine details in the image.

The Modulation Transfer Function is crucial for optimizing the design of lenses and improving the manufacturing process. Engineers can use the MTF to refine designs, address aberrations or limitations, and enhance the overall quality of the captured images. Furthermore, the MTF curve allows for meaningful comparisons between different lens assemblies or imaging systems, enabling engineers to make informed decisions. By leveraging the insights provided by the MTF, manufacturers can ensure their lenses meet the desired performance standards, researchers can evaluate and advance imaging technologies, and photographers can select lenses that best suit their needs for capturing high-resolution and high-contrast images.

No imaging system is perfect, and so the MTF curve of a real system will drop off at higher spatial frequencies due to factors such as lens wavefront aberrations.

Laser emittieren monochromatische kohärente elektromagnetische Strahlung im riesigen Wellenlängenbereich, der von den Millimeterwellen via Licht bis zur Röntgen-Strahlung reicht. Eine Übersicht über das elektromagnetische Spektrum in diesem Bereich gibt Tab. A 1 dieses Buches. Als neuartige Strahlungsquelle mit bisher unerreichten Eigenschaften revolutioniert der Laser die klassische Optik und verwandte Gebiete. Fast alle Begriffe der klassischen Optik und der Quantentheorie des Lichtes bekommen dadurch eine größere, ja sogar neue Bedeutung: elektromagnetische Wellen und Photonen, Beugung, Interferenz, Kohärenz, Polarisation, Photonenstatistik, Wechselwirkung elektromagnetischer Strahlung mit Elementarteilchen, Atomen, Molekülen, kondensierte Materie, Plasmen, etc. Im vorliegenden Kapitel wollen wir uns nur mit den Eigenschaften der elektromagnetischen Strahlung befassen, welche für viele vielleicht ungewohnt, jedoch für Laser relevant sind: Wellen- und Teilchennatur, Kohärenz und Photonenstatistik. Betreffend die für die Laser sonst wichtigen Begriffe der Optik, wie z. B. Beugung, Interferenz, Polarisation, verweisen wir auf Lehrbücher der Optik [Born 1933/1981, Born & Wolf 1959, Ditchburn 1976, Klein & Furtak 1988, Kneubühl 1994, 1997, Lipson & Lipson 1969, Meyer-Arendt 1972, Möller 1988, Schilling 1980].
