Abstract: 本發明提供用於控制來自一光源之光之顏色的光學回饋。以波長之離散階躍之一函數形式偵測該光之入射光能。針對波長之每一離散階躍，均產生一X、Y和Z三色刺激子值。將所有離散階躍之所有X、Y和Z三色刺激子值加總，產生該光的一X、Y和Z三色刺激值。使用該等X、Y和Z三色刺激值作為回饋來控制該光源所產生光之顏色。

Abstract: Provided are a hyperspectral sensor and a hyperspectral camera in which influence of external information such as a reflecting material is reduced such that the spectral data accuracy of a subject to be acquired can be improved. In the hyperspectral sensor in which light from a subject is split into light components in a plurality of wavelength ranges by a spectral optical element and each of the light components in the wavelength ranges is received by a sensor array consisting of a plurality of photodetection elements to acquire spectral data in which spectral information of the subject is associated with each of the photodetection elements, a polarization diffraction element that emits polarized light is used as the spectral optical element.

Abstract: An apparatus for characterization of one or more light sources over a field of view has an image relay disposed to relay a first image plane to a second image plane. An aperture defines the field of view at the first image plane. A diffraction grating in the path of light through the aperture is configured to form, on the first image plane, for at least one light source, a light pattern having at least two diffraction orders of light from the corresponding light source. An image sensor array is configured to provide image data from the light pattern at the second image plane.

Abstract: A holographic polymer dispersed liquid crystal (HPDLC) tunable filter exhibits switching times of no more than 20 microseconds. The HPDLC tunable filter can be utilized in a variety of applications. An HPDLC tunable filter stack can be utilized in a hyperspectral imaging system capable of spectrally multiplexing hyperspectral imaging data acquired while the hyperspectral imaging system is airborne. HPDLC tunable filter stacks can be utilized in high speed switchable optical shielding systems, for example as a coating for a visor or an aircraft canopy. These HPDLC tunable filter stacks can be fabricated using a spin coating apparatus and associated fabrication methods.
