There is provided an optical arrangement comprising a digital micromirror device (62) having a plurality of individually adjustable mirrors, a mirror pair formed from a convex mirror (70) and a concave mirror (72) having a common centre of curvature, the concave mirror (72) having a greater radius than the convex mirror (70), characterised in that a collimated space (76) is immediately adjacent the convex mirror (70), and the concave mirror (72) is offset from the convex mirror (70) so as to be capable of forming an image at an effective focal length of the mirror pair. The convex mirror (70) and the concave mirror (72) have radii substantially in the proportion 2.5:1, the concave mirror having the greater radius. A confocal microscope using such an arrangement is also provided.

The invention provides a lightweight high numerical aperture imaging device (1) comprising two rotationally symmetric curved mirrors (1a), (1b), which can be combined with various other components to facilitate solar-powered flight (including via direct deflection of sunlight (2c), in a manner akin to a solar sail or via solar thermal propulsion (1c)), to facilitate terrestrial power generation, and other uses for high numerical aperture imaging devices, including, for example, achieving very high concentrations of light or other sorts of wave (or other sorts of physical entities that satisfy equivalent "ballistic" equations of motion), or being used in reverse to form a beam that has a small angle spread, producing super-resolving optical systems (for. example for photolithographic purposes) or facilitating interlinking of communication network components. A detailed method for designing such a device is also disclosed.

A photon concentrator includes an imaging photon concentrator (13) concentrating photons from a source (70) to an image point (14) and a non-imaging photon concentrator (30). The non-imaging photon concentrator (NIPC) has an entry aperture (33) coupling to the imaging photon concentrator near the image point. The NIPC also includes an exit aperture (35) wherein the entry aperture is larger than the exit aperture.

The present invention relates to an optical imaging apparatus, which comprises a display device, a reflection module, and an optical device. The display device displays a display information image. The reflection module is disposed on the display path of the display information image, shrinks the display information image, and reflects the display information image to form a reflection image. The optical device is disposed on the reflection path of the reflection image and reflects the reflection image to form a projection image. The head-up display according to the present invention is applicable to larger display devices with higher definition for providing better display content and effects. Beside, the image size may be adjusted in an optical method for solving the oversize problem of displays.

The invention provides an image-forming optical component, which comprises a concaved reflection surface for reflecting an incident light and a convexed reflection surface arranged opposite to the concaved reflection surface, wherein the concaved reflection surface reflects the incident light so that the incident light is condensed on the convexed reflection surface, and the convexed reflection surface is adapted to focus the incident light.

Quantitative fluorescence imaging systems and methods using angular illumination to obtain automatic focus information. Laser scanning (e.g., point or line scanning) with angular illumination in combination with an area imaging sensor, such as with a bi-telecentric scanner, is used to determine sample height (relative to a detection axis orthogonal to a platform holding the sample) and also correct for sample height in subsequent scans.
