Abstract:
An X-ray analysis apparatus comprises a central control device which includes means for recording simulated beam paths in the apparatus, thus enabling correction for the effects of radiation-optical deviations as well as of other deviations in the apparatus or a specimen on detection signals. Such a correction facility allows for construction of an apparatus having a large number of freedoms and hence a universal application.
Abstract:
Das Handmeßgerät ist zur optischen Reflexionsmessung an farbigen Objekten bestimmt und besteht aus einem Gehäuse (1) mit Meßwertanzeige (2) und Meßeinheit (3). Um die mit einem solchen Gerät vorzunehmenden Messungen bei Aufrechterhaltung einfacher Handhabung beschleunigen zu können, ist das Gerät derart ausgebildet, daß die Meßeinheit (3) am oder im mit Meßstreckensucheinrichtung (4) versehenen Gehäuse (1) längs einer Meßstrecke (MS) mindestens in gerader Richtung verschieblich gelagert ist. Für die Bewegung der Meßeinheit (3) ist diese mit einem im Gehäuse (1) angeordneten Verstellantrieb gekoppelt. Eine alternative Lösung der gestellten Aufgabe besteht darin, daß im oder am Gehäuse (1) eine Lichtquelle mit Schlitzblende zu Meßstreckenmarkierung und Reflexionslichterzeugung auf der Meßstrecke (MS) und über der Meßstrecke (MS) ein mindestens eine Diodenzeile enthaltender Sensor mit vorgeschaltetem Objektiv am Gehäuse angeordnet sind.
Abstract:
A targeting system for a spectrophotometer includes a plurality of fiber channels, including at least one measurement channel and at least one illumination channel. A slit assembly includes a translucent layer disposed adjacent the plurality of fiber channels, and reflective portion disposed adjacent the translucent layer. Each fiber channel includes a first end, the first end offset from the reflective portion of the slit assembly to allow light transfer from one fiber channel to an adjacent fiber channel. A light source is in optical communication with the at least one illumination channel. A sample plane is in optical communication with a second end of the measurement channel. The system is configured such that light is transmitted from the light source, through the at least one illumination channel, reflected off the slit assembly, transmitted through the measurement channel, and onto the sample plane.
Abstract:
In a Raman spectroscopy apparatus, exciting light is focussed on a sample (26) as a line focus (38). Spectra from points in the line focus are dispersed in rows 46 on a CCD detector (34), having a two-dimensional array of pixels. The line focus moves longitudinally in a direction Y relative to the sample. Simultaneously and synchronously, charge is shifted in a parallel direction Y' within the CCD, so that data from a given point in the sample continues to accumulate, hi order to provide averaging in the X direction during fast, low resolution scanning, the line focus is swept across the sample in a zig-zag fashion, between boundary lines 60.
Abstract:
The present invention relates to a remote sensing device (20), in particular for tracking changes in agricultural crops, comprising a single optical channel (4, 5) and a plurality of elementary sensors (8 xy ) that are arranged in a matrix array (8) of preset shape, wherein each elementary sensor (8 xy ) is a multi-spectral sensor, in particular sensitive in a plurality of spectral bands, preferably at least in one spectral band in the visible domain (B, G, R) and one spectral band in the near infrared (IR). The present invention also relates to a remote sensing system employing such a remote sensing device (20).
