Abstract:
An electro-optical system for the carrying out of radiometric measurements of luminous sources comprises an instrument equipped with: a sensor comprising a pixel matrix, an optical system for creating the image of an external luminous source on the sensitive surface of the sensor, an optical bandpass filter, interposed between the sensor and the external luminous source for separating the spectrum of radiation emitted by the external luminous source into two portions: the first portion having a relatively limited bandwidth is transmitted toward the sensor while the second does not reach the sensor; moreover, the system comprises a computer which, starting from the plurality of monochromatic images recorded from the sensor, allows the calculating both of the angular distribution of the incident luminous radiation on the instrument and the irradiance on the normal plane in the direction from which the luminous radiation originates.
Abstract:
The present subject matter relates to methods of high-speed analysis of product samples during production of the product. Light is directed to a portion of a product under analysis and reflected from or transmitted through the product toward optical detectors. Signals from the optical detectors are compared to determine characteristics of the product under analysis. Temperature within the monitoring system may be monitored in order to provide compensation for the signals produced by the optical detectors. The products under analysis may be stationary, moved by an inspection point by conveyor or other means, or may be contained within a container, the container including a window portion through which the product illuminating light may pass.
Abstract:
A method and a low-cost, robust and simple system for remote sensing and analyzing properties of targets as a means to detect and identify them is introduced. The system can be highly portable but is usable in fixed locations or combination thereof. An aspect of the method and system includes the capability to distribute, modulate, aperture and spectrally analyze radiation emitted or absorbed by a volumetric target chemical species (solid, liquid or gas) or a target surface. Radiation is first collected by a single light gathering device (20), such as a lens, telescope, or mirror and then distributed to multiple detectors (8) through spectrally discriminating components (9) and if desired through apertures to achieve this desired detection and identification.
Abstract:
A cartridge (10, 60, 80, 110, 130, 140, 170, 180, 200, 222, 224, 226, 228, 230, 240, 242, 246, 280, 282, 300) and cartridge system (220) for use in an apparatus (12) for analyzing a sample (16) is provided. The cartridge has one or more light sources (18) and/or optical systems (22, 34, 84, 120, 162) and other components that are specific for a certain type of application such as fluorescence, absorbance, or luminescence. The light source, optical systems, and other components for a specific application are housed in a single cartridge. The system has a plurality of cartridges for different applications for a multimode instrument. The cartridges are removably engaged with the apparatus in a 'plug-in' format such that one cartridge may be removed from the apparatus and another cartridge may be easily installed.

Abstract:
Ein fotoelektrisches Handmessgerät besitzt ein Gehäuse (G), das an seiner Unterseite mit einem Messfenster (F) versehen ist, durch welches hindurch die fotoelektrische Ausmessung der Oberfläche eines Messobjekts erfolgt. Im Gehäuse ist eine Beleuchtungseinrichtung untergebracht zur Beaufschlagung des Messobjekts durch das Messfenster hindurch mit Beleuchtungslicht aus zwei zu einander senkrechten Raumrichtungen unter einem definierten, relativ kleinen Einfallswinkelbereich. Im Gehäuse befindet sich ferner eine optische Aufpickeinrichtung zum Auffangen des vom Messobjekt remittierten Messlichts durch das Messfenster hindurch unter einem definierten, relativ kleinen Aufpickwinkelbereich, eine von der Aufpickeinrichtung mit dem aufgefangenen Messlicht beaufschlagbare fotoelektrische Wandlereinrichtung zur Umwandlung des Messlichts in entsprechende elektrische Messsignale und eine elektronische Verarbeitungseinrichtung für die elektrischen Messsignale. Das Gehäuse (G) ist an seiner Vorderseite mit einer seitlichen Messnische (N) versehen, welche durch ein bewegliches Wandteil nach aussen hin geöffnet und geschlossen werden kann. Das Messfenster (F) ist im Bereich der Messnische (N) so angeordnet, dass das Messfenster bei geöffneter Messnische frei sichtbar ist. Ferner ist ein motorischer Antrieb vorgesehen, um das Wandteil zu bewegen und dadurch die Messnische (N) zu öffnen bzw. zu schliessen.
