Abstract: A projector includes a holding casing having a hole structure, a projection lens movably disposed through the hole structure, a containing casing detachably fixed to the holding casing for forming a containing space, an image projection module disposed in the containing space, and a flexible washer. A first engaging structure is formed on an external surface of the projection lens. The flexible washer jackets the projection lens and has first and second ring structures and a connection ring structure formed therebetween. The first engaging structure is engaged with the second engaging structure of the first ring structure for positioning the first ring structure on the projection lens. The second ring structure is clamped between the holding casing and the containing casing for sealing the containing space cooperatively with the connection ring structure and the first ring structure when the containing casing is fixed to the holding casing.

Abstract: A projector includes a projector body having a light-permissive aperture, a plurality of lens modules, a lens disassembly sensing module, a light-emitting module and a control module. The lens modules are individually provided for an assembly to the light-permissive aperture. The lens disassembly sensing module is disposed in the projector body and corresponding to the light-permissive aperture. The light-emitting module is disposed in the projector body and configured to emit lights toward the light-permissive aperture. The control module is signally connected to the lens disassembly sensing module and the light-emitting module. The control module is configured to sense, through the lens disassembly sensing module, whether any one of lens modules is being disassembled from the light-permissive aperture and modulate a lighting intensity of the light-emitting module when a lens module being disassembled from the light-permissive aperture is sensed. A light pollution shielding method for the projector is also provided.

Abstract: A touch projection system includes a light source device, a micromirror device, and an image-capturing device. The micromirror device can provide three reflection directions. The micromirror device can selectively reflect projection light emitted by the light source device in one of the reflection directions to project the reflected projection light onto a screen to form an image. The micromirror device also can reflect image light from the screen in another one of the reflection directions. Further, the micromirror device can reflect the image light from the screen in the other one of the reflection directions, which has a larger deflection angle, to be received by the image-capturing device, for example for determining a touch operation performed on the screen. Thereby, the limitation of structural interference by other components to the image-capturing device is reduced, so that the touch projection system can be assembled in a compact configuration.

Abstract: A touch projection system includes a screen, an image-capturing device, a micromirror device, and a TIR prism disposed in front of the micromirror device. The TIR prism includes an optical path compensation structure or a hollowed channel, so that an image light from the screen, traveling through the TIR prism to be reflected by the micromirror device, can travel through the optical path compensation structure or the hollowed channel to avoid a probable optical path difference on the image light due to traveling through the TIR prism. Thereby, the invention can solve that a distortion may be induced in a touch image formed by the image-capturing device receiving the image light reflected by the micromirror device.

Abstract: A projector includes a color wheel module and an optical engine. The color wheel module includes a rotation device, a mount, a color wheel, and an optical sensor. The color wheel is fixed on a rotary part of the rotation device. The rotation device and the optical sensor are fixed on the mount. The mount has an anti-dust structure includes a curved surface that is opposite to a rotary surface of the rotary part and extends in a rotation direction of the rotary part. The curved surface and the optical sensor are arranged sequentially in the rotation direction. Either by shortening a distance between the curved surface and the rotary surface or by a guiding slot that is disposed beside or lower than the curved surface, dust deposited on the optical sensor can be reduced effectively.

Abstract: A three-dimensional contour scanning device including an image sensing element, a light source and a single polarity element is provided. The light source is used for emitting a projection light to a to-be-scanned object through a projection optical path. The projection light reflected from the to-be-scanned object becomes an imaging light further reflected to the image sensing element through an image-formed optical path. The single polarity element is disposed on the projection optical path and the image-formed optical path.
