    摘要： A micro-electromechanical device for controlling compressed fluid flow is provided. A chamber includes a fluid flow inlet port, a high pressure region exceeding 30 bar, and a fluid flow outlet port. A moveable micro-electromechanical valve is positioned to contact the fluid flow outlet port when the moveable micro-electromechanical valve is in a first position. An electrical connection to the moveable micro-electromechanical valve provides an electrical pulse train to the moveable micro-electromechanical valve to actuate the valve at a rate of 10 KHz or more to move the valve in order to control fluid communication between the high pressure region and a low pressure region downstream from the fluid flow outlet port.

    摘要： An apparatus (10) for obtaining an image of a tooth (20) includes an image sensor and a white light source (12) providing broadband polychromatic light and an ultraviolet light source providing narrow-band light. A combiner (15) directs broadband polychromatic light and narrow band light along a common illumination path to illuminate the tooth. A polarization beamsplitter (18) directs polarized light from the illumination path along an optical axis (216). An optical coherence tomography (OCT) imaging apparatus (70) splits the low coherence light into a sample path and a reference path and a dichroic element (78) directs the polarized illumination and the sample path low coherence light along the optical axis. An image processor (100) identifies a region of interest according to either a white light image (124), a fluorescent light image (120), or both and the OCT imaging apparatus obtains an OCT image over the region of interest.
