Abstract
A spectrophotometric analysis helps us to know the characteristics of the materials. Digital cameras acquire color images by means of a sensor with a color filter array consists in red (R), green (G) and blue (B) filters. Therefore, digital cameras cannot restructure original spectrum of object due to measure only the light intensity of RGB. To restructure spectrum with higher quality, cameras need the function of spectrophotometry. In this work, we show using FDTD simulation that pinholes on the light-shielding metal selects wave of specific wavelength.
