Abstract: Apparatus and methods relating to photonic bandgap optical nanostructures are described. Such optical nanostructures may exhibit prohibited photonic bandgaps or allowed photonic bands, and may be used to reject (e.g., block or attenuate) radiation at a first wavelength while allowing transmission of radiation at a second wavelength. Examples of photonic bandgap optical nanostructures includes periodic and quasi-periodic structures, with periodicity or quasi-periodicity in one, two, or three dimensions and structural variations in at least two dimensions. Such photonic bandgap optical nanostructures may be formed in integrated devices that include photodiodes and CMOS circuitry arranged to analyze radiation received by the photodiodes.

Abstract: A polarized light imaging apparatus for separating light from a superficial single-scattering layer of a sample and its deeper diffuse layer as a function of space is disclosed. The apparatus has a light source for producing light beams; an illumination optic coupled to the light source for guiding the light beams towards the sample; a linear polarizer coupled to the illumination optic; a non-total internal reflection (TIR) birefringent polarizing prism (BPP) communicatively coupled to the sample to maximize a refraction difference between ordinary waves and extraordinary waves of light returning from the sample; and a detection optic unit coupled to the non-TIR BPP for guiding the light waves returning from the sample towards a single polarization sensitive sensor element.

Abstract: Provided is an aperture-plate drive mechanism including an aperture-plate open-close mechanism and a rotation mechanism for rotating the open-close mechanism. The open-close mechanism includes: drive blocks 308 fixed to a pair of aperture plates 301; a linear motion guide 306 allowing the drive blocks to move along an axis; a feed screw 302 parallel to the axis, on which a pair of helical threads proceedimg in opposite directions formed; nut members 305 each of which is provided in a manner to be engaged with one of the pair of helical threads and is prevented from rotating due to a rotation of the feed screw; an urging member 309 for pressing the drive blocks onto the nut members, respectively; and a distance adjustment member 310 placed between one drive block and the corresponding nut member, for adjusting the distance between them. With this mechanism, a discrepancy between the open-close center of the aperture plates from the rotation center can be cancelled even after the mechanism is assembled.
