摘要： An apparatus may include an interface to allow a scanning beam device to be coupled. The apparatus may include at least four lasers optically coupled with the interface. Each of the at least four lasers may provide a different wavelength visible spectrum light to the scanning beam device through the interface. An actuator driver of the apparatus may be electrically coupled with the interface. The actuator driver may provide actuator drive signals to the scanning beam device through the interface. The actuator drive signals may be operable to cause the scanning beam device to scan a beam of the different wavelength lights over a surface. An image generation unit of the apparatus may generate an image of the surface. The image may be generated based, at least in part, on light from the beam that has been reflected from the surface and detected by at least one photodetector.

摘要： Methods, systems, and devices can determine spatial relationships between a probe and a target surface. Specular reflections from the target surface vary dramatically with small changes in angle between the scanning beam and the target surface, and as the geometry of the beam scanner and light detector of the probe are often known, and as the angle of the light beam projected from a scanner for accurately generating an image, the pattern of spectral light reflected from the light beam directly back to the detector allows the distance between the probe and the target surface, and/or the angular relationship between the probe and the target surface, to be calculated.

摘要： A miniature optical scanner includes an electromagnetic drive having stationary magnets and stationary drive coils to minimize the rotational inertia of the scanner and increase the scanner's resonant frequency. The scanner is such that the resonant frequency is manually tunable as well as automatically adjustable to compensate for variables causing frequency drift. The optical scan angle is increased by employing a multiplying mirror with the optical scanner. For a two axis scanning system, the multiplying mirror may be formed of a second optical scanner to increase the optical scan angle relative to both of the axes.

摘要： A scanning beam display controls the curvature of scanning light wave impinging on the eye to simulate image points of differing depth. To simulate an object at a far distance the generated light waves are flatter. To simulate closer objects, the light wave curvature increases. When changing the curvature of the light waves, the eye responds by altering its focus. The curvature of the light waves thus determines the apparent focal distance from the eye to the virtual object. To vary the curvature, either a variable focus lens or a variable index of refraction device is used. Alternatively, a moving point source is used. The generated apparent distance of a virtual object is correlated to a detected distance in a background field of view. Intensity of the virtual object is correlated to detected intensity of background light.
摘要翻译：扫描光束显示器控制冲击眼睛的扫描光波的曲率，以模拟不同深度的图像点。为了在远距离模拟物体，产生的光波更平坦。为了模拟更近的物体，光波曲率增加。当改变光波的曲率时，眼睛通过改变其焦点来作出响应。因此，光波的曲率决定了从眼睛到虚拟物体的视在焦距。为了改变曲率，使用可变焦距透镜或可变折射率折射率装置。或者，使用移动点源。所产生的虚拟对象的视距与背景视野中的检测距离相关。虚拟物体的强度与背景光的检测强度相关。
