Abstract: The invention provides a DLP micro projector including: a light supply device, including: a LED light source and a light collimation system, and a spectroscope group; a light path switching device, including a fly-eye lens or an optical wand; a lighting optical system, including: a freeform lens or a freeform reflector, and a right angle prism; a DMD light modulator being parallel to a right angle side of the right angle prism; and a projection lens group. The DLP micro projector has a simple and reasonable structure, employs a freeform optical component to replace the conventional planar mirror and relay lens to redirect and converge the beams, and meanwhile compensates the lighting source of the DMD light modulator, thereby simplifying the optical components and reducing the size and weight of the DLP micro projector. The projector features a compact structure, small size, low production cost, and high projection performance.

Abstract: The invention provides a linear DLP pico-projector including a light supply device, the light supply device including: a first LED light source and a corresponding vertical collimation lens group thereof, a second LED light source and a corresponding horizontal collimation lens group thereof, and a spectroscope group; a light path switching device, the light path switching device including a fly-eye lens or an optical wand; a lighting optical system, the lighting optical system including: a first freeform surface optical component or a lens group including a first right angle prism and a second freeform surface optical component, and a second right angle prism; a DLP light modulator, and a projection lens group. The linear DLP pico-projector employs the combination of the freeform surface optical component and the right angle prism to replace the conventional reflection mirror and cemented prism to redirect the beam, thereby simplifying the optical components and enabling them to be almost linearized.

Abstract: A composition and method for detecting the ability of a compound to modulate the activity of LGR4, LGR5, or LGR6 receptors in a cell. LGR4, LGR5, and LGR6 are capable of activating the Wnt/?-catenin signaling system which plays essential roles in embryonic development and in the self-renewal and maintenance of adult stem cells.
