摘要： A T.V. surveillance camera is disclosed. The camera comprises a lens (1), and electronic means (8, 9, 10) for deriving video signals (S) from images focused by the lens (1) onto image sensors (4, 6). Separating means (2) are provided to (a) separate essentially visible light (V) from the lens (1) and pass that light (V) to a first sensor (4), and (b) separate essentially infra-red light (IR) from the lens (1) and pass that light (IR) to an image intensifier (5) coupled to a second sensor (6). The image intensifier (5) is preferred to be a Gen 3 intensifier. Separation may be effected by means of a dichroic mirror (2) reflecting light below 700 nm and transmitting light above 700 nm, with a reflecting mirror (3) to correct the reversal of the dichroic mirror (2).

摘要： A long range laser illuminator is disclosed that is suitable for providing illumination for camera systems at ranges up to approximately 20km. The illuminator incorporates a diverger that allows for a compact, low F-number optical arrangement that improves eye safety by reducing the power density across a primary optical element, such as a spherical or parabolic mirror. The diverger may be located at an end of an optical fibre feed, or between a pair of optical fibres. The diverger may incorporate a diffuser, such as a "top hat" diffuser. The optical fibre feeds may be highly multi mode, to provide for a more even illumination. The illuminator incorporates means for altering a focus of the output light beam, to allow an illuminated spot size to be altered. The illuminator is particularly suitable for use at night, where it may be used alongside a camera system.

摘要： A surveillance apparatus, particularly for viewing vehicle number plates in covert, night operations, comprises an illuminator (10) having an array of light-emitting diodes (11) or a source of laser light, and a shuttered, preferably-miniature TV camera. The illuminator emits a series of high-peak pulses of infrared light (17) outside the range visible to the human eye, which reflect from a number plate (13) to be received by the camera which operates in synchronism with the illuminator. It is preferred to have the illuminator (10) positioned close to the camera lens (15) to minimise the included angle (Υ) between incident light (17) and reflected light (16).
