摘要： A non-scanning heterodyne optical imaging sensor which utilizes a multi-frequency coherent light source to provide a plurality of points of different frequencies on a single detector on which the image of an object is also projected. Each point acts as a local oscillator which is sensed/filtered to construct the image of the object without mechanical scanning.

摘要： A system for reducing the effects of background radiation on a desired signal includes a plurality of physically spaced phase shifters arranged in a two-dimensional array and disposed in the path of the desired signal for cancelling the background radiation while passing the desired signal without substantial attentuation. In a second embodiment, the desired signal is split into two beams which traverse different paths and passed through two complementary two-dimensional arrays of physically spaced attenuators, each array being disposed in one of the paths. A phase shifter is disposed in one or both of the paths and the signals from the two paths are recombined to cancel the background radiation. The two-dimensional arrays of physically spaced phase shifters may be integrated into the beam splitters.

摘要： An ophthalmoscopic camera with an achromatic objective arranged on a common optical axis of an image forming lens in front of a photographic film and adapted to project a ring-shaped bundle of illuminating light rays onto the cornea of an eye to be photographed as the illuminating light rays come from a light source through a relay lens after reflection from an apertured mirror positioned between the objective and the image forming lens at an angle with the optical axis thereof. For an increase in the angle of view, the objective is constructed in the form of a biconvex triplet consisting of a forwardly convex negative meniscus lens, an equiconvex lens and a rearwardly convex negative meniscus lens with its four refracting surfaces so configured and so separated that a beam of image forming rays passing through a central aperture of the illuminating mirror to the film can be made free from disturbing light reflections from these four lens surfaces by use of a single black spot positioned at a point between the light source and the mirror in coaxial relation thereto.

摘要： A lens structure formed by materials in different refractive indexes includes a transparent sphere in a first refractive index as well as a transparent second lens in a second refractive index. The first refractive index is different from the second refractive index, and the sphere is a round ball formed by a first portion and a second portion which are equipped with a first light condensing effect. The first lens is formed on the first portion of the sphere, the second portion of the sphere is exposed out of the first lens, and the first lens is provided with a first light absorption curve opposite to the first portion of the sphere, so that a light beam can pass through the second portion of the sphere to form the first light condensing effect, and then pass through the first light absorption curve to form a second light condensing effect.

摘要： A lens structure formed by materials in different refractive indexes includes a sphere, a first lens and a separation layer which is disposed between the sphere and the first lens. The sphere and the first lens have a different refractive index and the sphere is a round ball. The first lens is formed on the sphere that part of the sphere is exposed out of the first lens, and the first lens includes a first light absorption curve. The separation layer includes a transparent section opposite to the first light absorption curve. When a light beam passes through the second portion of the sphere to form a first light condensing effect and enter the sphere, the light beam will then pass through the transparent section to enter the first lens, forming a second light condensing effect after passing through the first light absorption curve.

摘要： Among other things, a method comprises imaging a sample displaced between a sensor surface and a surface of a microscopy sample chamber to produce an image of at least a part of the sample. The image is produced using lensless optical microscopy, and the sample contains at least blood from a subject. The method also comprises automatically differentiating cells of different types in the image, generating a count of one or more cell types based on the automatic differentiation, and deriving a radiation dose the subject has absorbed based on the count.
