| Abstract: | The veiling glare of an optical system is the major specification for opprasing its imaging quality.Black-spot method for testing the veiling glare is a currently comon-used technique.In the letter,the method is put forwerd that is the method of comparing the two beams from a same source of light,using a bridge diffrential circuit.It is proved that the testing precision is as high as 10 4 by the calculation and experiments. |
