A light guiding device is operable to receive incident light emitted by a light source through a capture surface. The received light exits the light guiding device through an exit surface provided adjacent to and aligned with an aperture of light receiver. In this manner, light from the light source can be inserted into the receiver where it may be combined with additional incident light captured by the receiver. The light source might be a projector and the light projected may correspond to operational data relating to the operation of the receiver or images corresponding to data captured by a further receiver device operating with a different form of sensor or in a different region of the spectrum. In order to improve the composite image observed by a user of the light receiving device, the operation of the light source can be controlled to vary the intensity of the light emitted. In one example, this variation can be in response to the ambient light level, as sensed by a suitable sensor. An additional or alternative variation is to vary the intensity in a pulsed manner between a peak and a low level.

Abrégé

A microbolometer comprises an array of sensor elements or ‘pixels’ each individually responsive to generate an output indicative of the intensity of infrared radiation incident thereupon. In practice there are significant non-uniformities in the response of each pixel and further processing of the outputs must take place to generate an accurate image. These non-uniformities are dealt with by means of individual correction factors to be applied to the outputs of each pixel in the image. Commonly, the correction used provides a constant offset (1pt) and a linear gain correction (2pt). As the optimal values of these corrections drifts over time it is still necessary to provide further correction. In the present invention this is achieved by calculating one or more common scalar correction parameters that when applied to all of the individual correction factors before they are used to correct the output of the sensor elements will minimize the differences between the corrected outputs of adjacent sensor elements in the array when summed over a particular selection of sensor elements in the array.
