Embodiment 1

[0031] This embodiment provides a system integrating a projector and a spectrometer, and its optical path structure is as follows figure 1 and figure 2 shown, where figure 1 shows the state of the system working in spectral analysis mode, figure 2 Shown is the system in projection mode, the system is switchable between these two operating modes. The system integrated with a projector and a spectrometer provided in this embodiment includes the following components.

[0032] The illumination light source is used to provide illumination light beams, including a light-emitting element 101, a reflective element 104, a color wheel 2, and a beam homogenizing unit 3. The beam homogenizing unit 3 includes a beam homogenizer (such as an integrating rod, a microlens array, etc. ) and the light-gathering element, wherein the light 100 emitted by the light-emitting element 101 is converged onto the color wheel 2 by the reflective element 104, and then passes through the color wheel 2 ...

Abstract

The invention provides a system integrated with a projector and a spectrometer; the projector comprises a spatial light modulator and a projection element; the spectrometer comprises a detector and the spatial light modulator commonly used by the projector; the spatial light modulator comprises a plurality of independently controlled units; each unit of the units can adjust an emitting direction of the light emitted to the unit; relative positions of the spatial light modulator, the detector and the projection unit are arranged in the following mode: when each unit of the spatial light modulator is in a first state, the light emitted to the units can be modulated and emitted to the detector; when the units are in a second state, the light emitted to the units can be modulated and emitted to the projection element. The invention also provides a mobile communication device comprising the said system.

Description

technical field [0001] The invention relates to the field of optical equipment, in particular to projectors and spectrometers. Background technique [0002] In recent years, projectors have been greatly developed, which can generate high-quality images, and are compact and light in weight, providing a good solution for large-screen display. In particular, projectors based on DLP (Digital Light Processing, digital light processing) have achieved greater success, which can avoid the use of larger polarizing optical components required by liquid crystal display projectors. The basic structure of a DLP-based projector usually includes a light source, a DLP component (such as a digital micro-mirror, etc.), a projection component, and the like. In order to display color images, the projector also usually has a color wheel. When the white light emitted by the light source passes through the color wheel, red light, green light, and blue light are generated in turn, and images corre...
