摘要： The invention provides a projection device including a first display, a second display, a third display, a light-combining module, a first angle selector, a second angle selector, a third angle selector, and a projection lens. The first display, the second display, and the third display are respectively adapted to provide a first image beam, a second image beam, and a third image beam. The projection lens is configured on one side of a light-outgoing surface of the light-combining module, and is adapted to project the first image beam, the second image beam, and the third image beam out of the projection device. The first image beam, the second image beam, and the third image beam respectively pass through the first angle selector, the second angle selector, and the third angle selector, and are then transmitted to the projection lens by the light-combining module.

摘要： The present disclosure provides an apparatus and method for wavefront reconstruction based on rotationally symmetric extended structured light illumination. The apparatus includes a laser device, a neutral density filter, a microscope objective, a pinhole, a collimating lens, a beam splitter prism, a spatial light modulator, a lens to be measured, and an image acquisition device that are sequentially arranged. The method permits modulation of incident parallel light into phase grating-like structured light by using a spatial light modulator. Based on the characteristic of non-infinitely small pixel unit of the spatial light modulator, changing the modulation pattern of the spatial light modulator may result in different forms of structured light. Not only the object to be measured but also the real structured light wavefront can be recovered by acquiring diffraction spots at the focal plane and simultaneously updating the object plane and the structured light plane using an algorithm

摘要： A device for interfering with the optical navigation capability of an organism moving in air, comprising at least a detector, a projector and a control device connected to the detector and the projector, which is characterized in that using the detector a biological feature of an organism may be identified by way of at least a signal, wherein the control device then determines the trajectory of the organism and, in dependence on the species and trajectory of the organism, indicates a light pattern, which may be projected using the projector.

摘要： A vehicle-mounted dual-oblique asymmetric laser velocity measurement device is provided. A small-angle splitting prism (9) is installed on a laser path where the laser beam of the reference-beam LDV probe is incident onto a driving surface. The laser beam is split by the small-angle splitting prism (9) into two emergent beams having an included angle α for incidence onto the driving surface. Two ground-scattered light beams returning along the original direction of the two emergent beams are used as signal light together. Reference light is mixed with the signal light on a photosensitive surface of a photodetector of the reference beam LDV probe. The photodetector mixes the reference light and the signal light to form Doppler signals for transmission to a signal processing unit (10). The signal processing unit (10) extracts the Doppler frequencies corresponding to the two emergent beams separately, to implement velocity calculation.
