1. A sensing system comprising:
i) a fibre optic plate (FOP) comprising a proximal end, a distal end and a body situated between said proximal and distal ends and the FOP further comprising at least one optical fibre;
ii) at least one illumination component; and
iii) an image sensor proximate to said FOP;
configured so that said image sensor is about 0.6 to about 50 microns from said proximal end of said FOP and a refractive index matching zone is between said image sensor and said proximal end of said FOP and said at least one optical fibre is arranged longitudinally along the body of said FOP allowing for transmission of an image from one end of said FOP to the other end of said FOP and said at least one optical fibre has a Numerical Aperture (NA) from about 0.0001 to about 0.4, and the FOP has a length of less than about 20 mm and said FOP has light absorbing cladding,
wherein said image sensor further comprises a dynamic range comprising hardware and software high dynamic range and extended dynamic range, variable hardware pixel binning and a variable frame rate per second (FPS), and said illumination component provides pulse illumination, and said image sensor is a camera with no lens.
