X-ray device with folded field-of-view

An X-ray device comprising:

• an X-ray source configured to emit X-rays;
• a scintillator arranged to absorb, on a first side of the scintillator, the X-rays after interaction with an object that has been placed in the X-ray device, the scintillator being configured to emit light from a second side of the scintillator in response to absorption of the X-rays;
• a single mirror arranged to reflect the light from the second side of the scintillator toward a camera;
• and
• the camera arranged to receive the light reflected from the single mirror;
• wherein
• the camera has a field-of-view around an optical axis of the camera,
• the single mirror is large enough to fully contain the field-of-view as the field-of-view is folded by the single mirror toward the scintillator,
• the single mirror is positioned at an angle with respect to a plane that is normal to the optical axis at a point where the optical axis intersects the single mirror,
• the angle is decreased from forty-five degrees to reduce a volume of the folded field-of-view of the camera, and
• the angle is greater than or equal to a threshold angle that prevents triple specular reflections of light between the single mirror and the scintillator, the threshold angle being set in accordance with (i) a first distance along the optical axis between the camera and the scintillator, (ii) a second distance along the optical axis between the single mirror and the scintillator, and (iii) a size of the scintillator.
