| 摘要 |
The invention relates to an optical detector device (1) for generating at least one electrical output signal in response to a received beam of light, comprising an optical band-pass filter (3a), adapted to receive the beam of light and to provide a filtered beam of light, which filter (3a) has a transmission wavelength which increases in direction of at least one axis (4) and an array of detector elements (2) arranged in direction of the axis (4) to receive the filtered beam of light for generating the electrical output signal. |
