Abstract
A detect device and a detect method for transmittivity spectrum of the light guiding plate are provided. The detect device comprises a mixing cavity unit for providing a linear light source with continuous spectrum to a light guiding plate to be detected; a light guiding plate placing unit located at a side of the mixing cavity unit, on which the light guiding plate to be detected is disposed to receive light from the mixing cavity unit; and a detecting lens disposed above the light guiding plate placing unit for detect the spectrum.
