Abstract: The present invention has a problem aiming to provide a birefringence measurement device capable of measuring a two-dimensional distribution of birefringence in a measurement target in real time and in detail using a simple configuration without a rotating mechanism. A birefringence measurement device 1A according to the present invention includes light flux generating means 2 for generating light flux L1, light flux irradiating means 3, 4, or 5 for irradiating a measurement target 20 with the light flux L1 in a predetermined polarization state, an imaging optical system 10 for forming an image from light flux L4 transmitted through the measurement target 20, a polarization/diffraction grating 8 disposed in a position within the imaging optical system 10, image pickup means 12 for generating a light-dark signal related to brightness of the image formed by the imaging optical system 10, and output means for outputting information regarding a phase difference for the light flux L4, the phase difference resulting from the transmission through the measurement target 20 and being determined on the basis of the light-dark signal, and the image pickup means 12 generates the light-dark signal for an image based on at least one beam of diffracted light L7 from among a plurality of beams of diffracted light produced by the polarization/diffraction grating 8.

Abstract: A device including an optical measuring device and an optical system which can measure the light intensity of the scattered light from the sample and the spatial distribution of the scattered light and which is excellent in the sensitivity is provided. In the device, the image distortion is suppressed by providing such a structure that the light emitted from the first substance is reflected by the ellipsoidal mirror two or more even times before reaching the second substance. The image distortion is suppressed by arranging two ellipsoidal mirrors so that respective one focuses are set to a common focus while remaining other two focuses are arranged on one line so as to be opposite to each other across the common focus, setting the common focus to a blank, arranging a first substance on one of the focuses, and arranging a second substance on the other of the focuses.
