Abstract: Ein Handfarbmessgerät umfasst ein Gehäuse mit einer opto-elektronischen Messeinheit. Diese umfasst eine Optikanordnung zum Empfangen von Messlicht und eine vom Messlicht beaufschlagte Sensoranordnung, welche das Messlicht in elektrische Messsignale umwandelt und diese zu digitalen Messdaten verarbeitet. Die Messeinheit (M) besteht aus einer asphärischen Eingangslinse (L 1 ), einer Blende (B) zur Begrenzung des Einfallswinkelbereichs, einem depolarisierenden Diffusor (D), einer Sensor-Linse (L 2 ) und mindestens drei durch Farbfilter (F 1 , F 2 , F 3 ) auf unterschiedliche spektrale Empfindlichkeiten sensibilisierte Sensoren (S 1 , S 2 , S 3 ). Die Blende (B) liegt im Wesentlichen in der Brennebene der Eingangslinse (L 1 ), der Diffusor (D) ist in unmittelbarer Nähe der Blende (B) und in der Brennebene der Sensor-Linse (L 2 ) angeordnet. Die Filter (F 1 , F 2 , F 3 ) und die Sensoren (S 1 , S 2 , S 3 ) sind nahe der optischen Achse (A) angeordnet und werden mit im Wesentlichen parallelem Messlicht beaufschlagt. Die Filter (F 1 , F 2 , F 3 ) sind auf die spektralen Charakteristiken der Color Matching Functions des Standard-Beobachters nach CIE 1931 ausgelegt. Für Umgebungslichtmessungen kann ein zusätzlicher Diffusor (D E ) der Eingangslinse vorgesetzt werden.

Abstract: A disc serving as a spatial radiation modulator has dispersed radiation filters thereon. Each filter has a transmittance or reflectance modulation function of the form sin 2 (mθ +π/4), where m is a positive integer and p has one of the four values 0, 1, 2, 3. A radiation beam including selected wavelength components is diffracted into an elongated image dispersed according to wavelength. Different wavelength components are focused onto different filters on the modulator and are encoded by corresponding filters. Since the modulation functions of the filters are orthogonal to one another, it is possible to extract the amplitude of each wavelength component after it has been encoded or modulated by corresponding filter from the total detected signal during one measurement.

Abstract: An apparatus for enhancing the selectivity for spectroscopic measurements of analytes in a turbid medium is described. In one example, spatial filters are used to select only certain radii from the medium to be imaged. This selection is accomplished by placing an optical obstruction on the surface of the medium or at an image plane of the surface later in the optical imaging system. In one implementation, this is achieved by placing a fiber bundle at an image plane of the collecting optical system and then using a spacer of appropriate size at the center of the fiber bundle to act as a central obstruction.

Abstract: A spectroscopic microscope includes a laser or other light source which emits light from the entrance aperture of its spectrograph, and also includes a light sensor situated on the microscope sample stage upon which a specimen is to be situated for microscopic/spectrometric analysis. The sample stage is positioned such that the signal from the light sensor is maximized, thereby indicating good alignment between the sample stage and spectrograph. Additionally, the microscope sample stage bears a light source which can emit light to be detected by a light sensor situated at the vantage point of a user/viewer utilizing the microscope, and such a light sensor can simply take the form of a video camera or other image recordation unit associated with the microscope. The sample stage can also be positioned to optimize the signal at the light sensor to signify good alignment between the sample stage and the microscope.

Abstract: The disclosure relates to a portable and/or handheld bioagent detector and methodology described herein that is based in part on advanced Raman Chemical Imaging ('RCI') technology. According to one embodiment of the present disclosure, the detection system may include a fiber array spectral translator ('FAST') and may also include a probe which may include a complementary metal oxide semiconductor (CMOS) camera. The probe alleviates the need to place the main instrument close to an unconfined release of a potentially hazardous material and facilitates analysis of a sample that is situated in a hard-to-reach location while minimizing contamination of the detector and operator.
