摘要： A lensmeter includes a light emission portion, a light reception portion, a storage unit, a display unit and a display control unit. The light emission portion emits light so as to radiate the light onto a lens-to-be-inspected. The light reception portion receives the light transmitted through the lens-to-be-inspected to measure an optical characteristic of the lens-to-be-inspected. The storage unit stores a measured value of the optical characteristic of the lens-to-be-inspected. The display unit displays the measured value of the optical characteristic of the lens-to-be-inspected stored in the storage unit. The display control unit causes the display unit to display a target pattern including at least two different colors, and changes the target pattern in accordance with the measured value stored in the storage unit.

摘要： Optical coherence tomography (OCT) apparatuses and methods include a first electro-magnetic radiation (EMR) source providing EMR to a first optical path associated with a sample and a second optical path associated with a reference. A multi-beam generator unit (MBGU) generates first and second EMR beams having different wavelength contents. A scanning system illuminates the sample with the first and second EMR beams, at a first and second time, at a first and second location. An interference module generates interference signals based on received EMR returning from the reference and the first and second EMR beams returning from the sample. A detector generates detection signals based on received interference signals and a processor generates OCT data based on the processed detection signals. In some embodiments, three EMR beams having different wavelength contents with linearly independent vectors illuminate at least one same location of the sample.

摘要： Apparatus and method for optical coherence tomography. The method includes orienting a first optical path in a first selected orientation in space relative to a second optical path, having lights of the first optical path and the second optical path with no preferential polarization direction relationship. A sample is scanned with light from the first optical path and the second optical path. Light returning from the sample is directed, along the first optical path and the second optical path, to an optical pathway leading to a processing system. The processing system is configured to perform optical coherence tomography motion analysis based on interferences between at least one reference light and at least two lights returning from the sample, at two different instants, and from nearby scanned locations.

摘要： An optical coherence tomography apparatus includes a multi-beam configuration unit comprising at least a first optical path having a first numerical aperture and a second optical path having a second numerical aperture. The multi-beam configuration unit orients the second optical path in a selected orientation in space relative to the first optical path. A scan system illuminates a sample with non-polarized light received from the multi-beam configuration unit and directs light returning from the sample to the first optical path and the second optical path. The multi-beam configuration unit directs light returning from the sample, along the first optical path and the second optical path, to an optical pathway leading to a processing system. The processing system performs optical coherence tomography motion analysis based on interference between light returning from the sample and a first reference signal.
