An image pickup device is put on the side of the transparent member the same as that of a light source and takes reflected light including regular reflection from an interface between an adhered object on the other surface of the transparent member and air. Assuming an incident angle of the emitted light on the transparent member when the light reflected in regular reflection by the other surface of the transparent member is incident on the image pickup lens being θs, an incident angle of a typical light beam of the emitted light falls within θs−30 deg through θs and an incident angle of a main element of the emitted light is less than θs.

摘要： A spectral image acquiring apparatus includes an optical filter on which light is incident; an image sensor including a two-dimensionally disposed pixel array for detecting the light via the optical filter; and a signal processing unit generating a difference-value image based on a detection signal from the image sensor. The optical filter includes a diffraction grating having a lattice pattern corresponding to one or more pixels on the image sensor. The signal processing unit calculates a difference value in an amount of received light between two adjacent pixels based on the detection signal from the image sensor, and generates the difference-value image based on the difference value. The difference value between the two adjacent pixels is varied depending on a difference in an interference point on the image sensor corresponding to a diffraction angle of the light that has passed through the diffraction grating.

A period of the periodic structure is equal to or less than the wavelength of the incident light. The incident light having the wavelength is resonated and reflected by a resonance caused between the incident light and the protrusions and recessions. Widths of the protrusions are spatially changed.

摘要： Disclosed is a reflecting wavelength plate that deflects and reflects a light path and adds a phase difference with respect to plural incident light having different wavelengths. The reflecting wavelength plate includes a substrate; a reflecting film laminated on the substrate; and a sub-wavelength concavo-convex structure that is laminated on the reflecting film and has a pitch less than or equal to the shortest wavelength of the plural incident light. The filling factor and the groove depth of the sub-wavelength concavo-convex structure are determined so as to add the phase difference obtained by (kπ)/8, where k is an integer, to the plural incident light having the different wavelengths.
