A method for monitoring at least one biomedical characteristic is disclosed. A first microneedle coated with one or more regions of a chemical sensing material is illuminated. One or more digital images are captured of the first microneedle, wherein at least one of the one or more digital images is captured after the first coated microneedle has been actuated to penetrate a subject's skin. Pixel information is spatially extracted from the captured one or more images to define one or more pixel sample areas corresponding to the one or more regions of a chemical sensing material. One or more spectral characteristics are determined for each of the one or more pixel sample areas. The at least one biomedical characteristic is determined for each of the one or more pixel sample areas based on the determined one or more spectral characteristics for each of the one or more pixel sample areas.

When producing an image in an optical scanning device, such as an optical scanning device employing pulse width modulation, for example, edges are reproduced by illuminating, within a pixel through which an edge passes, an off-centered location towards the lighter illumination side of the edge. Such a technique reproduces an edge with reduced jagging and with accurate color as compared to conventional displays.

A substantially monocentric arrangement of optical components providing a multicolor stereoscopic display having an expanded color gamut. A virtual image is electronically generated by an image generation system (70) having four or more color light sources (20) and is projected, as a real intermediate image, near the focal surface (22) of a curved mirror (24) by means of a scanning ball lens assembly (100). To form each left and right intermediate image component, a separate image generation system (70) comprises a scanning ball lens assembly (100) that uses a spherical lens (46) for wide field of view and a reflective surface (102). A monocentric arrangement of optical components images the left and right scanning ball lens pupil at the corresponding left and right viewing pupil (14) of the observer (12) and essentially provides a single center of curvature for projection components. Use of such a monocentric arrangement with electromechanical grating light modulator (85) as a linear image source and scanning ball lens assemblies (100) provides an exceptionally wide field of view with large viewing pupil (14). The use of four or more light sources (20) provides an expanded color gamut.

Preferably, the positive image on the right-positioned transparency and the positive image on the left-positioned transparency are of a similar main subject shown in front of a similar background, with the main subject in the two transparencies being in at least slightly different locations relative to the background to appear to be viewed from at least slightly different perspectives when looking at the two transparencies.
