    Abstract: Aspects of the present disclosure relate a head-worn computer with a see-through display wherein computer content is presented to a user wearing the head-worn computer and through which the user sees a surrounding environment, wherein the see-through display generates image light comprised of narrow bandwidths of red, green and blue light and wherein the see-through display further includes a tristimulus notch mirror positioned to reflect the image light towards the user's eye, and wherein the tristimulus notch mirror reflects less than a full width half max of the red image light.

    Abstract: A laser interferometer includes a light source that emits first laser light, an optical modulator that includes a vibrator and modulates the first laser light by using the vibrator to generate second laser light including a modulated signal, a photodetector that receives interference light between third laser light including a sample signal generated by reflecting the first laser light on an object and the second laser light to output a light reception signal, a demodulation circuit that demodulates the sample signal from the light reception signal based on a reference signal, and an oscillation circuit that outputs the reference signal to the demodulation circuit, and the vibrator is a signal source of the oscillation circuit.

    Abstract: In the optical composite sheet according to an embodiment, optical functional elements such as a prism sheet and a light diffusion layer are combined, and a light absorbing layer that selectively absorbs light of a specific wavelength band is inserted, so that the optical performance and color gamut can be enhanced as compared with the prior art. In particular, it is possible to minimize the decrease in luminance due to the absorption of light by the light absorbing layer while enhancing the color gamut by adjusting the lamination configuration of the optical composite sheet.

    Abstract: The present disclosure is directed to an optical system having a reduction conjugate point on a reduction side and a magnification conjugate point on a magnification side that are optically conjugate with each other, and includes a prism including a first transmission surface located on the reduction side, a second transmission surface located on the magnification side, and at least three reflection surfaces located on an optical path therebetween, wherein in the meridional plane, two light rays traveling in a direction perpendicular to the first rectangular region from two points on the first rectangular region intersect at two intersection positions after passing through the first transmission surface and then reflected by the at least three reflection surfaces and before passing through the second transmission surface, and the number of reflection of the two light rays intersecting at each intersection position before reaching the respective intersection positions is the same.
