    Abstract: A device for detecting optical radiation with a focusing means (1) for focusing to a focal plane and a detector means (8) with at least one detector element (12) in a detector plane (9) is described. It is primarily characterized by at least one optical fibre (2, 3) which guides radiation from the focal plane to the detector plane (9). An optical element (6) with substantially the same refractive index as that in the optical fibre (2, 3) is arranged between inlet plane (5) of the optical fibre and the focusing means (1). The radiation coming into said inlet plane (5) forms the angle (delta) with the longitudinal axis (10) of the optical fibre, which in turn forms the angle (alpha) with a normal to the exit plane (7) of the optical fibre. If (alpha) is greater than 1,5 (delta), radiation reflected from the detector plane (9) spreads outside the focusing means. (alpha) shall be smaller than the angle that means total reflection in the exit plane (7) of the optical fibre.

    Abstract: Embodiments of the present disclosure provide methods and apparatuses for detecting an ambient light illuminance and for computing a correction coefficient, and an electronic device. The method for detecting an ambient light illuminance includes: filtering ambient light based on a monochromatic channel, such that a quantum efficiency curve of the filtered light matches a spectral luminous efficiency curve; and performing photoelectric detection on the filtered light to obtain an illuminance level of the ambient light. In solutions of the embodiments of the present disclosure, the photoelectric detection may be equivalent to obtaining an illuminance level of light by convolutional computation based on a spectral luminous efficiency curve, and therefore, when the quantum efficiency curve for a monochromatic waveband obtained by filtering ambient light based on a monochromatic channel matches the spectral luminous efficiency curve, a reliable spectral luminous efficiency curve can be obtained with a small computing workload.
