    Abstract: In known spectrophometers, a single light source is used to illuminate both a sample and a reference. A single detector is used to detect the light at both the sample and the reference. A chopper wheel having aperture portions is used to allow the light to pass through a selected filter in the apertures. However, in such devices, the beams from the sample and the reference arrive at the detector at the same time and movable shutters need to be employed. Described herein is a spectrophotometer (10) comprising a single light source (12), a single detector (14), optics (30, 36, 340, 42, 44, 46, 48, 50, 52, 54, 56, 58, 90, 92, 100) for dually and alternatively reading a sample (94) and a reference (96), and which employs only one moving part. That moving part is a chopper (42) containing multiple pass-through apertures (60a, 60b, 60c, 60d, 60e, 60f), each filled with a unique bandpass filter to select wavelengths to specifically illuminate the sample (94) or reference (96). To inform the spectrophotometer (10) whether and when it is reading the sample (94) or the reference (96), energy relay means (70a, 70b, 70c, 70d, 70e, 70f, 70g, 70h, 70i, 70j, 70k, 70l) are provided between an energy emitter (80) and an energy detector (82) in an amount of at least twice the number of the pass-through apertures (60a, 60b, 60c, 60d, 60e, 60f).

    Abstract: A micro-Raman device includes a first laser light source, a second laser light source, a first holder, a second holder, a first ND filter, and a second ND filter. The first laser light source and the second laser light source generate first laser light of a first wavelength and second laser light of a second wavelength, respectively. The second wavelength is different from the first wavelength. The first laser light and the second laser light proceed in a second direction orthogonal to a first direction while being separated from each other in the first direction. The first holder and the second holder are arranged overlapping each other in the second direction.

    Abstract: An imaging apparatus and method are provided for improving discrimination between parts of a scene enabling enhancement of an object in the scene. A camera unit is arranged to capture first and second images from the scene in first and second distinct and spectrally spaced apart wavebands. An image processing unit processes the images so captured and processes polarimetric information in the images to enable better discrimination between parts of the scene. An image of the scene, including a graphical display of the polarimetric information, may be displayed on a visual display unit thus enhancing an object in the scene for viewing by a user. Correlation parameters indicating, possibly on a pixel-by-pixel basis, the correlation between the actual image intensity at each angle of polarization and a modelled expected image intensity may be used to enhance the visibility of an object.

    Abstract: A spectral camera for producing a spectral output is disclosed. The spectral camera has an objective lens for producing an image, a mosaic of filters for passing different bands of the optical spectrum, and a sensor array arranged to detect pixels of the image at the different bands passed by the filters, wherein for each of the pixels, the sensor array has a cluster of sensor elements for detecting the different bands, and the mosaic has a corresponding cluster of filters of different bands, integrated on the sensor element so that the image can be detected simultaneously at the different bands. Further, the filters are first order Fabry-Perot filters, which can give any desired passband to give high spectral definition. Cross talk can be reduced since there is no longer a parasitic cavity.

    Abstract: A calibration system (300) for a detector (328) includes a base member (302), a plurality of radiation sources (304)fixedly attached to the base member, and a positioning mechanism (306) attached to the base member. Each radiation source (394) is maintained at a different temperature and is configured to emit electromagnetic radiation. The positioning mechanism includes a movable member (308) having a single degree of freedom with respect to the base member (302), and a plurality of optical elements arranged (310) on the movable member. Each optical element corresponds (310) to one of the radiation sources (304) and each optical element is configured to at least be movable between a calibration position and a non-calibration position. When the optical element is in the calibration position, the optical element is configured to receive the electromagnetic radiation from its corresponding radiation source and to reflect the electromagnetic radiation to a detector.
