摘要: According to one aspect and example, a holographic recording system includes a light source, an object for modulating an object beam from the light source, and a relay system adapted to magnify (positive or negative) the modulated beam (e.g., an image of the object) to an output image. The object may include an SLM operable to modulate the object beam with an information layer comprising a plurality of data pages. The output image is directed to the holographic storage medium, where a reference beam is also directed, to record the resulting interference pattern. Additionally, the relay system converges the output image to an output Fourier plane, which may be disposed within the holographic storage medium. A filter may be placed at an intermediate Fourier plane located prior to the output Fourier plane, and a phase mask may be placed at the position of the output image.

摘要: The unsuitability of the retina of the eye as a reflective projection screen for image observation causes objective optometry to be expensive and of limited accuracy. The subjective assessment of image quality is the only way to make full use of the resolution capability of the eye. A subjective optometer for home use is disclosed with ample accuracy and confidence for mail order of prescription glasses. It overcomes the disadvantages of subjective optometry and is able to measure the refractive errors to the resolution limit of the eye, which is of great importance for the present state and relief of ametropia. Electronic recording and connectivity can be provided as an option.

摘要: Disclosed are optical systems and methods of producing obliquity corrected light beams, for example, holographic recording and retrieval systems that utilize an obliquity corrected reference beam. One method includes directing a light beam reflected from a prism mirror to a reference plane with an angle of incidence to the reference plane, wherein the prism mirror varies the width of the light beam according to the angle of incidence to the reference plane. The optical system may include a holographic data storage system and the reference plane may be associated with a holographic storage medium.

摘要: Optical systems (1-19) for endoscopes and the like are characterized by an integrated design in which the locations of the components and the aberration corrections are no longer tied to the optical functions of the objective (1-6) and the relays (7-19), and in which the relays may depart from symmetry. The power requirements can thus be shifted from one group to another, thereby reducing the overall power requirement. Moreover, the aberration correction can be shared between the optical group of the integrated system.

摘要: An endoscope whose magnification may be continuously varied from zero to a microscopic magnification of 40.times. or more while providing full correction for aberrations at widely different magnifications. The objective comprises a positive lens group in a microscope objective configuration, and a front group which typically includes a negative lens generally near the focal plane of the positive lens group. To achieve high magnification, the objective is moved away from the transfer optics, and placed in contact with the object to be viewed. In such a configuration, the positive lens group functions as a microscope objective while the negative lens group's contribution to the aberrations is small. At low magnification, the negative lens group cooperates with the positive lens group to provide a wide angle lens. Pupil stabilization is achieved by placing the physical stop so that when the endoscope is used in the microscope mode, the physical stop between the positive and negative lens groups is ineffective or marginally effective. This permits the maximum numerical aperture consistent with the physical diameter of the positive lens group. However, the physical stop between the positive and negative lens groups comes into play when the object plane moves away from the negative lens group. The field lens located at the image plane receives the marginal chief ray at a nearly constant small angle over the entire range of magnification. This allows image transfer to be achieved with conventional means such as alternating field and relay lenses.

摘要: Optical systems for endoscopes, borescopes, dental scopes, and the like which are characterized by having three groups of lenses of positive optical power and an external entrance pupil. Typically, all three groups of lenses are displaced from the pupil and focal planes. As a consequence, the displaced groups take part in the image transfer as well as in the pupil transfer. The optical power requirements can thus be shifted from one group to another, distributing as well as reducing the overall power requirement. Moreover, the aberration correction can also be shared between these groups. The first group, which conventionally has the highest optical power, and consequently a large amount of aberrations to be corrected, can in this way transfer some of the optical aberration correction to the other groups. The sharing of the optical functions and aberration correction results in a fully integrated optical system. The reduction in the total amount of optical power is so large that a line-of-sight deviating prism can be readily accommodated between the entrance pupil and the first lens group. The resulting simplicity of the optical system makes it suitable as a disposable item.
