摘要： The invention describes several embodiments of an adapter which can make use of the devices in any commercially available digital cameras to accomplish different functions, such as a fundus camera, as a microscope or as an en-face optical coherence tomography (OCT) to produce constant depth OCT images or as a Fourier domain (channelled spectrum) optical coherence tomography to produce a reflectivity profile in the depth of an object or cross section OCT images, or depth resolved volumes,. The invention admits addition of confocal detection and provides simultaneous measurements or imaging in at least two channels, confocal and OCT, where the confocal channel provides an en-face image simultaneous with the acquisition of OCT cross sections, to guide the acquisition as well as to be used subsequently in the visualisation of OCT images.Different technical solutions are provided for the assembly of one or two digital cameras which together with such adapters lead to modular and portable high resolution imaging systems which can accomplish various functions with a minimum of extra components while adapting the elements in the digital camera. The cost of such adapters is comparable with that of commercial digital cameras, i.e. the total cost of such assemblies of commercially digital cameras and dedicated adapters to accomplish high resolution imaging are at a fraction of the cost of dedicated stand alone instruments. Embodiments and methods are presented to employ colour cameras and their associated optical sources to deliver simultaneous signals using their colour sensor parts to provide spectroscopic information, phase shifting interferometry in one step, depth range extension, polarisation, angular measurements and spectroscopic Fourier domain (channelled spectrum) optical coherence tomography in as many spectral bands simultaneously as the number of colour parts of the photodetector sensor in the digital camera. In conjunction with simultaneous acquisition of a confocal image, at least 4 channels can simultaneously be provided using the three color parts of conventional color cameras to deliver three OCT images in addition to the confocal image.

摘要： Polarization-sensitive optical coherence devices for obtaining birefringence information are presented. The polarization state of the optical radiation outgoing from the optical radiation source is controlled such that the polarization state of the optical radiation incident on a sample has a 45 degrees angle with respect to the anisotropy axis of the sample. A combination optical radiation is produced in a secondary interferometer by combining a sample portion with a reference portion of optical radiation reflected from a tip of an optical fiber of the optical fiber probe. Subject to a preset optical path length difference of the arms of the secondary interferometer, a cross-polarized, and/or a parallel-polarized component of the combined optical radiation, are selected. Time domain and frequency domain registration are provided. The performance of the device is substantially independent from the orientation of the optical fiber probe with respect to the sample.

摘要： Variable Sensitivity optical sensors can have a respective actual sensitivity of one or more portions of the sensor corresponding, at least in part, to a selected environment of each respective sensor portion. Some disclosed sensors have a plurality of optical conduits extending longitudinally of the sensors. At least one of the optical conduits can have at least one longitudinally extending segment having one or more optical and/or mechanical properties that differs from the optical properties of an adjacent longitudinally extending segment, providing the conduit with longitudinally varying signal propagation characteristics. An optical sensor having such optical conduits can exhibit a longitudinally varying actual sensitivity. Nonetheless, such a sensor can exhibit a substantially constant apparent sensitivity, e.g., when each respective portion of the sensor exhibits an actual sensitivity corresponding to a selected environment. Innovative sensors can provide a low- incidence of false or nuisance alarms, accurate position and magnitude information, and other advantages.

摘要： An interferometric sensing arrangement includes an interferometric sensor having an optical path length that varies depending on one or more physical parameters to be measured using the interferometric sensor. One or more light sources are used to generate light at three or more predetermined different fixed wavelengths. In a preferred example embodiment, four fixed wavelength lasers are used to generate light at four predetermined different fixed wavelengths. An optical coupler couples the multiple wavelength light to the interferometric sensor, and a detector measures an amplitude response of an interferometric signal produced by the interferometric sensor. A controller determines the optical path length based on the measured amplitude response.
