Abstract
A fibrescope comprises a scintillator arranged to produce light of a first wavelength upon exposure to radiation; an optical system arranged to receive and direct light of the first wavelength emitted from the scintillator, the light being received at one end of the optical system, and wherein one or more elements of the optical system emits scintillation light of a second wavelength upon exposure to radiation; and an optical filter, disposed at the other end of the optical system, and arranged to transmit light of the first wavelength and block light of the second wavelength. The scintillator is chosen such that the light of the first wavelength is spectrally distinct from the light of the second wavelength.

A fibrescope comprising:
- a scintillator arranged to produce light of a first wavelength upon exposure to radiation;
- an optical system arranged to receive and direct light of the first wavelength emitted from the scintillator, the light being received at one end of the optical system, and wherein one or more elements of the optical system emits scintillation light of a second wavelength upon exposure to radiation;
- and
- an optical filter, disposed at the other end of the optical system, and arranged to transmit light of the first wavelength and block light of the second wavelength;
- wherein, the scintillator is chosen such that the light of the first wavelength is spectrally distinct from the light of the second wavelength.
A method for imaging radiation sources, wherein the method comprises the steps of:
- receiving radiation at a scintillator, wherein the scintillator emits light of a first wavelength in response to the radiation;
- receiving radiation at one or more further elements of the optical system, wherein the one or more further elements emits scintillation light of a second wavelength;
- and
- transmitting the light of the first wavelength whilst filtering out the light of the second wavelength at the optical filter.
A fibrescope comprising:
- a first scintillator arranged to produce light of a first wavelength upon exposure to radiation;
- a second scintillator arranged to produce light of a second wavelength upon exposure to radiation;
- an optical system arranged to receive and direct light of the first and second wavelengths emitted from the first and second scintillators respectively, the light being received at one end of the optical system, and wherein one or more elements of the optical system emits scintillation light of a third wavelength upon exposure to radiation;
- and
- an optical filter, disposed at the other end of the optical system, and arranged to transmit light of one or more of the first and second wavelengths, and block light of the third wavelength;
- wherein, the first and second scintillators are chosen such that the light of the first wavelength is spectrally distinct from the light of the second wavelength;
- and
- wherein the first and second scintillators are chosen such that the light of the first and second wavelength is spectrally distinct from the light of the third wavelength.
A method for imaging radiation sources, wherein the method comprises the steps of:
- receiving radiation at a first scintillator, wherein the first scintillator emits light of a first wavelength in response to the radiation;
- receiving radiation at a second scintillator, wherein the second scintillator emits light of a second wavelength in response to the radiation;
- receiving radiation at one or more further elements of the optical system, wherein the one or more further elements emits scintillation light of a third wavelength;
