Embodiments of the present invention relate to a reflective focusing and transmissive projection device having a body, a set of reflective-focusing components and a light detector. The body has a surface layer with first and second surfaces, and a detecting layer outside the second surface. The set of reflective-focusing components is in the surface layer. Each reflective-focusing component has a contouring element and a curved reflective element conformed to the contouring element. The curved reflective element is configured to reflect light of a first type, transmit light of a second type and focus the light of the first type outside the first surface of the surface layer. The light detector is in the detecting layer, and is configured to receive light and generate light data associated with the received light. Also, the contouring element can be configured to focus the light of the second type on the light detector. |
