Photoelectric detector testing device and testing method

The invention relates to a photoelectric detector testing device and method, and the method comprises the steps: converting a relation curve between the input optical power of a photoelectric detector and a conversion current into a relation curve between the input current of a second light source and the conversion current of the photoelectric detector, so that the linearity test of the photoelectric detector does not depend on the optical power value of the light source any more; therefore, the use of light source calibration equipment is omitted in the test process, the evaluation of the linearity of the photoelectric detector is realized under the condition that the light source calibration equipment is not used, and the cost of evaluating the linearity of the photoelectric detector is remarkably reduced. Besides, the first light source and the second light source are simultaneously arranged in the photoelectric detector testing device provided by the invention, so that the first light source shares the o
