Abstract: Apparatus and methods are described for performing tear film structure measurement on a tear film of an eye of a subject. A broadband light source (100) is configured to generate broadband light. A spectrometer (250) is configured to measure a spectrum of light of the broadband light that is reflected from at least one spot on the tear film, the spot having a diameter of between 100 microns and 240 microns. A computer processor (28) is coupled to the spectrometer and configured to determine a characteristic of the tear film based upon the spectrum of light measured by the spectrometer. Other applications are also described.

Abstract: Apparatus and methods are described for optically analyzing an object having a plurality of layers, without needing to use a reference mirror. Light is generated using an extended broadband light source. The light is directed toward the object, such as to create respective images of the light source on the respective layers of the object. Light that is reflected from a point of the object is gathered into a conjugate point in a detector. The thicknesses of the plurality of layers at the point of the object are determined, by analyzing, within the gathered light, interference between light reflected from the plurality of layers of the object at the point. Other applications are also described.

Abstract: Apparatus and methods are described for optically analyzing an object having a plurality of layers, without needing to use a reference mirror. An extended broadband light source produces light, and directs the light toward the object, such as to create respective images of the light source on the respective layers of the object. An imaging system gathers light that is reflected from a point of the object into a conjugate point in the detector. The detector determines the thicknesses of the plurality of layers at the point of the object by analyzing, within the gathered light, interference between light reflected from the plurality of layers of the object at the point. Other applications are also described.

Abstract: Systems and methods for detecting physical characteristics of a multilayered tissue of a subject, such as a tear film including analyzing received detector-output indicative of optical properties of light reflected or deflected from the respective multilayered tissue, to determine spectral properties of the multilayered tissue; and determining physical characteristics of the multilayered tissue by using multiple spectral models of the of the multilayered tissue, each model being associated with spectral properties indicative of different tissue characteristics, wherein physical characteristics of the multilayered tissue are determined by hierarchal determination of a best-fit model from the multiple spectral models.

Abstract: Apparatus and methods are described for calibrating an optical system that is used for measuring optical properties of a portion of a subjects body. During a calibration stage, a front surface of a calibration object (300) is illuminated, light reflected from a plurality of points on the calibration object (300) is detected, and intensities of the light reflected from the plurality of points on the calibration object (300) are measured. During a measurement stage, the portion of the subjects body is illuminated, and light reflected from the portion of the subjects body is detected. Measurements performed upon the light that was reflected from the portion of the subjects body are calibrated, using the measured intensities of the light reflected from the plurality of points on the calibration object (300). Other applications are also described.
