Abstract:
A method is provided that includes discriminating an autofluorescence (AF) response of a lens tissue of an eye due to a current level of 2-(2-furoyl)-4(5)-furanyl-1H-imidazole (FFI) in the lens tissue by interrogating a lens tissue of an eye along a visual axis of the eye by activating an illuminator for a select time to produce interrogating irradiation having a peak wavelength of 425 nm to 460 nm, the illuminator comprising at least one light source and a focal lens positioned with respect to the light source. The method also includes obtaining at least one image of the autofluorescence response of the lens tissue from a detector, the detector including a digital camera unit, analyzing the at least one image to determine a total autofluorescence index of the lens tissue, and determining a current level of FFI in the lens tissue based, at least in part, on the total autofluorescence index.
Abstract:
A system and method for controlling the intensity of light into a cabin space is provided. The system includes a controller in communication with a window. The window is configured to have variable transmittance. The system further includes a sensor operable to detect the state of a pupil. The sensor is also in communication with the controller. The controller processes the state of an iris of a user so as to adjust the transmissivity of the window. Accordingly, the intensity of light entering into a cabin space may be controlled so as to facilitate the vision of the occupants.
