Abstract : This patent application discloses a high efficiency fiber-shaped detector having a longitudinally extending core transparent to the wavelength of an imcoming beam of electromagnetic radiation. Circumscribing the core and deposited thereon is an extremely thin layer of photosensitive material, an extremely thin layer of insulation and an extremely thin layer of reflective material. The photosensitive layer converts the electromagnetic radiation into an electrical signal which is transmitted to a processing system. Upon receiving the incoming beam of electromagnetic radiation, the reflective layer reflects this beam so that the beam passes through the photosensitive layer many times. Consequently, it is possible to provide a reliable indication of beam intensity. Modified embodiments of the above described detector also provide information with respect to the angularity and alignment of the input beam of electromagnetic radiation.
