Abstract: A hyperspectral/multispectral imager comprising a housing is provided. At least one light source is attached to the housing. An objective lens, in an optical communication path comprising originating and terminating ends, is further attached to the housing and causes light to (i) be backscattered by the tissue of a subject at the originating end and then (ii) pass through the objective lens to a beam steering element at the terminating end of the communication path inside the housing. The beam steering element has a plurality of operating modes each of which causes the element to be in optical communication with a different optical detector in a plurality of optical detectors offset from the optical communication path. Each respective detector filter in a plurality of detector filters covers a corresponding optical detector in the plurality of optical detectors thereby filtering light received by the corresponding detector from the beam steering element.

Abstract: An object identification device includes an image capturing device to capture images polarized in different directions. A noise removal unit removes noise in the polarized images using a noise removing parameter. An index value computing unit computes an object identification index value for identification-processing areas in the polarized images using data of noise-removed polarized images. An object identification processing unit conducts object identification by determining identification processing areas corresponding to an identification target object based on the object identification index value. An environment information obtaining unit obtains environment information. An environmental condition determination unit determines an environmental condition based on the environment information. A parameter storage unit stores noise removing parameters prepared for mutually exclusive environmental conditions. The noise removal unit reads a noise removing parameter from the parameter storage unit to conduct noise removal. A method of identifying an object and a spectroscopic image capturing apparatus are also provided.

Abstract: A temperature insensitive (athermal) channeled spectropolarimeter (CSP) is described. The athermal CSP includes a crystal retarder formed of a biaxial crystal. The crystal retarder has three crystal axes, wherein each axis has its own distinct index of refraction. The axes are oriented in a particular manner, causing an amplitude modulating carrier frequency induced by the crystal retarder to be thermally invariant. Accordingly, a calibration beam technique can be used over a relatively wide range of ambient temperatures, with a common calibration data set.
