CCD performance parameter testing device and testing method

The invention relates to the field of light sensation device performance testing, in particular to a CCD performance parameter testing device and a testing method. The CCD performance parameter testing device comprises a PC control module, a main integrating sphere, an opaque chamber, a first illuminometer, a three-dimensional loading platform, stabilized power supply and auxiliary integrating spheres which are arranged on an hemisphere, at the side of a light output port, of the main integrating sphere; light sources of the CCD performance parameter testing device are provided by the multiple auxiliary integrating spheres arranged on the main integrating sphere and the light sources have a double-light-mixing effect so that light output by the main integrating sphere can be better in the homogeneity, light output ports of the auxiliary integrating spheres are provided with adjustable light bars so that a testing light source with continuously variable illuminance and a more stable color temperature can be provided; and meanwhile, illuminometers and the method from a CCD to be tested to the light output ports are automatically switched over in an alternating mode so that a measuring result can be more accurate.
