摘要： A method and device for highly accurate corneal topographical mapping and a device for effecting the mapping for use in effecting vision correction by removal of corneal tissue. The method and device involve use of a modified optical interferometer with directing of a coherent light beam, such as from a laser, to the anterior surface of a cornea; splitting the beam so that half the beam is directed to a reference object having a predetermined shape; capturing the reflected light from the cornea and the reference object so as to form an interference pattern; and using the interference pattern to determine deviations or displacements of the corneal surface from the known reference shape. The deviations are then utilized in corneal tissue removing procedures, such as RK, PRK and RLK, by determination of the extent and position of tissue removal. With a modified RLK procedure, the deviations are used in preparing an appropriate corneal template for use with a keratome using a high speed water jet as the cutting means.

摘要： A mechanism for achieving single frequency output in a semiconductor laser diode is disclosed. In accordance with the invention, a conventional laser diode having an anti-reflection coating on its output facet is coupled to a single mode fiber output pigtail having an anti-reflection coating on its input facet. The anti-reflection coatings suppress Fabry-Perot type feedback which would normally be effective for a large number of wavelengths. The fiber includes a built-in distributed Bragg reflector grating, which grating is located just beyond the output fiber input facet. The grating supplies feedback that is effective only over a narrow wavelength band approximating the wavelength spacing between the actual longitudinal modes of the structure so that the laser produces only a single frequency output.

摘要： In contrast to existing light addressed light valves for projection displays which use a homogeneous CdS or Se photoconductive layer as the control element for a liquid crystal cell, a silicon photo-diode array is disclosed which makes an effective control element capable of applying a spatially varying AC voltage across a liquid crystal light valve. Writing may be done with a miniature CRT in an optical or electron excitation mode. It is shown that for a video mode the ratio of diode capacitance to liquid crystal cell capacitance associated with the diode, and the frequency of the applied square wave voltage, define the buildup or decay time of the liquid crystal cell voltage. Thus, the frequency of the applied AC voltage can be used to control sensitivity and transient response and there is no lag. The dynamic range of the cell voltage is shown to depend on the ratio of diode capacitance to liquid crystal cell capacitance. The display can be used in a storage mode by erasing with an AC voltage and writing with a constant voltage. The silicon photodiode array is compatible with a CCD frame store using direct minority carrer injection for writing. This light addressed version thus represents a desirable milestone in achieving an all solid-state projection display.

摘要： A read/write system is disclosed for optical disc apparatus. The light source is removed from the head and optically coupled to the disc by a single-mode fiber which acts as a spatial filter. Adverse effects on the light source due to reflection from the disc are avoided by making the fiber length greater than one-half the coherence length of the source. A sparing switch and combiner component may be included in the system. An array of discrete light sources, each coupled to an associated fiber, may also be employed for multiple track accessing.

摘要： A semiconductor heterojunction optical loss modulator section (30), having an anti-reflection coating (52) on its optical output beam facet (32), is located with an opposite facet (31) optically coupled to, and closely spaced from, a semiconductor heterojunction laser section (20) having substantially the same cross-section structure as the loss modulator section (30). The laser section is operated CW in a single mode. In this way, the output beam (50) emanating from the laser section (20) and passing through the anti-reflection coating (52) can be coupled into an optical fiber (60) for transmission purposes. This output beam (50) is substantially single frequency and is intensity modulated, in a signal-pattern independent fashion, in accordance with an electrical signal applied to the loss modulator section (30).
