Abstract:
An imaging system, comprising,a radiation source having a first wavelength emission; a first conduit providing a path for radiation between said radiation source and a selected imaging object; an electromagnetic focussing imaging detector providing an output signal in response to an applied optical image, wherein said magnetically focussed image detector comprises: a photocathode disposed to receive photons and provide electrons corresponding to the intensity of the received photons, one of a CCD and a CMOS detector disposed a selected distance from said photocathode to receive said electrons, means for urging said electrons toward said one of a CCD and a CMOS detector from said photocathode, and a magnetic field source disposed to provide a magnetic field along said selected distance, wherein said electrons are caused to move in a helical path toward said one of a CCD and a CMOS detector of selected radius change; and a second conduit for applying said optical image to said focussing imaging detector from said selected imaging object.
