Detection method and evaluation method for one-way perspective performance of curtain

The invention discloses a detection method and an evaluation method for one-way perspective performance of a curtain, and is used for testing the one-way perspective performance of the curtain. The detection method comprises the following steps: arranging a simulation light source in front of a dark box, arranging a first eye chart and an internal light source in the dark box, arranging a second eye chart at the simulation light source; wetting a curtain sample before detection, taking a curtain sample with a proper size from the curtain sample and covering on a front opening of the dark box;fixing an illumination of the internal light source and the simulation light source; observing the first eye chart and the second eye chart through the curtain sample at the simulation light source and a rear opening of the dark box respectively, and performing subsequent testing steps according to an observation result. The illumination and the light transmittance of the sample surface are testedusing a luminometer by si
