Abstract: A multi-spectral camera comprises a blocking element (201) having at least one hole (203) allowing light through. A dispersive element (205) spreads light from the at least one hole (203) in different wavelength dependent directions and a lens (207) focuses light from the dispersive element (205) on an image plane (209). A microlens array (211) receives light from the lens (207) and an image sensor (213) receives the light from the microlens array (211) and generates a pixel value signal which comprises incident light values for the pixels of the image sensor (213). A processor then generates a multi-spectral image from the pixel value signal. The approach may allow a single instantaneous sensor measurement to provide a multi-spectral image comprising at least one spatial dimension and one spectral dimension. The multi-spectral image may be generated by post-processing of the sensor output and no physical filtering or moving parts are necessary.

Abstract: An apparatus and method for noninvasive determination of analyte properties of human tissue by quantitative infrared spectroscopy to clinically relevant levels of precision and accuracy. The system includes subsystems optimized to contend with the complexities of the tissue spectrum, high signal-to-noise ratio and photometric accuracy requirements, tissue sampling errors, calibration maintenance problems, and calibration transfer problems. The subsystems can include an illumination/modulation subsystem, a tissue sampling subsystem, a data acquisition subsystem, a computing subsystem, and a calibration subsystem. The invention can provide analyte property determination and identity determination or verification from the same spectroscopic information, making unauthorized use or misleading results less likely than in systems that use separate analyte and identity determinations. The invention can be used to control and monitor individuals accessing controlled environments.

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.

Abstract: A light amount is increased and an analyzing accuracy can be kept in accordance with an enlargement of a load angle, however, a scattered light tends to be loaded in an analysis accompanying the scattered light and a dynamic range of a concentration which can be measured becomes narrow. A light is dispersed by a light dispersing portion, a load angle of the received light is changed per wavelength, the load angle is made larger in the light of a wavelength having a small light amount, and the load angle is made smaller in the light a wavelength having a large light amount and used for an analysis accompanying a scattered light. Accordingly, it is possible to gain a dynamic range of a concentration which can be measured in the analysis accompanying the scattered light, while increasing the light amount and maintaining the analyzing accuracy.

A first spectrum of the second electro-magnetic radiation can be dispersed along at least one first dispersive axis with respect to a propagation direction of the second electro-magnetic radiation. In addition, it is possible to, using at least one second arrangement, receive the second electro-magnetic radiation and produce at least one third electromagnetic radiation having a second spectrum dispersed along at least one second dispersive axis with respect to a propagation direction of the third electromagnetic radiation. The orientations of the respective first and second dispersive axes can be different from one another. The first and/or second dispersive arrangements can be VIPA etalon arrangements.
