Abstract: A system for providing active real-time characterization of an article under test is disclosed. An infrared light source, a first visible light source and a second visible light source each outputs and directs a beam of coherent light at a particular area on the article under test. A visible light camera and a visible light second harmonic generation camera, an infrared camera and an infrared second harmonic generation camera, a sum frequency camera and a third order camera are each configured to receive a respective predetermined return beam of light from the particular area on the article under test. A processor receives signals from the cameras and calculates in real time respective spectroscopic signals and compares each calculated signal with each other calculated signal and with a predetermined baseline signal to ensure that the article under test conforms to an expected value.

Abstract: In polarization-sensitive optical image measurement, noise-containing OCT signals obtained by polarization OCT are processed using a birefringence calculation algorithm, to obtain measured birefringence, after which noise is statistically adjusted to simulate a measured birefringence distribution and determine the noise characteristics of the measured birefringence values, and then Monte Carlo calculations are repeated by assuming different values for the noise level and the true birefringence value, respectively, to form three-dimensional histogram of combinations of true birefringence values, SN ratios, and measured birefringence values, after which specified measured birefringence values and SN ratios are assumed from the three-dimensional histogram information to obtain a true birefringence probability density distribution, and true birefringence values are estimated from the true birefringence probability density distribution.

Abstract: In a system for analyzing optical properties of an object (350) a point source of light (100) composed of multiple spectral bands each having a respective amplitude, phase and polarization is converted by first optics (120, 150) into a line light source to illuminate an object line on the object. A beam splitter (200) splits the light exiting the first optics and directs a first portion of light on to the object (350) as an illuminated line and a second portion of the light on to a reference mirror (450). Second optics (500) collects respective first and second lines of light reflected by the object and mirror of and collinearly images the reflected lines of light as an image line on to an imaging spectrometer (550) wherein mutual interference allows determination of the optical properties of the object at each point along the object line.

Abstract: An excitation light source emits excitation light to a target sample. An image sensor includes pixels arranged one-dimensionally or two-dimensionally, and receives measurement light from the sample according to the excitation light. A polarization selector arranged between the sample and image sensor includes pixels arranged one-dimensionally or two-dimensionally. Each pixel receives a corresponding portion of the measurement light, selects light having a polarization direction that corresponds to a driving signal applied to the pixels, and supplies this light to the image sensor. A measurement control unit supplies the cyclic driving signal having a first period T1, and acquires data I1, I2, I3, and I4 from each pixel of the image sensor for each exposure time segment T2=T1/4 obtained by dividing the first period T1 by 4.
