摘要： A differential interference imaging system capable of rapidly changing shear direction and amount includes: a light source (101), a filter (102), a polarizer (103), a sample stage (104), an infinite imaging microobjective (105), a tube lens (106), a shear component, an analyzer (113), and an image sensor (114). After the light intensity and a polarization direction is adjusted, the linearly polarized light passes through a transparent sample, to be collected by the infinite imaging microobjective (105) and to implement imaging through the tube lens (106). An imaging beam is divided into two linearly polarized light fields which are perpendicular to each other in the polarization directions and have tiny shear amount, then they are further combined into an interference light filed by the analyzer (103) to form a differential interference image in the image sensor (114). The system may be flexibly assembled, is simple in structure and easy to implement.

摘要： The invention relates to a procedure for determining an identification of a sample of material, or its properties. Electromagnetic radiation from a radiation source (1) is reflected or transmitted through the sample. The radiation from the sample is collected and analyzed over several channels (7, 7', 7"), which modulate the radiation with a spectral transmission function which is unique for each channel. The modulated radiation is transmitted to one or several detectors (9, 9', 9") which produce output signals which are further electronically processed. The spectral range of each of the individual channels is common to all of the channels. Within the common range the channels are provided with different spectral transmission functions (7, 7',7") which are optimally chosen for a given application.

摘要： A method for phase contrasting-correlation spectroscopy: converting an incident linearly polarized light into two polarized components (polarized divergent and convergent components, wherein the polarized divergent component is orthogonal to the polarized convergent component), focusing each of the polarized divergent component and the polarized convergent component into a focal plane, thereby producing two focus planes constituting a reference focus (RF) plane and a sample focus (SF) plane; placing a sample at the SF plane and ambient conditions of the sample at the RF plane, resulting in a phase shift between the two polarized components; reconstituting the two phase-shifted polarized components into a phase-shifted linearly polarized light; detecting the phase-shifted linearly polarized light; calculating phase and intensity of the sample from the phase-shifted linearly polarized light; establishing an autocorrelation of phase and intensity of the phase-shifted linearly polarized light; and generating correlograms of intensity and phase of the phase-shifted linearly polarized light.

摘要： An angle-stable, miniaturized and integrate-able imaging system based on plasmon resonances or dielectric resonances for multispectral imaging maintaining full spatial resolution of the image sensor. Active tunability of the filter allows color recording, estimation of unknown spectra and determination of spectral singularities, for example laser lines, with the use of a conventional B/W camera. The system is characterized by high angular acceptance, cost-efficient fabrication and ease-of-use. This system can be used in conjunction with other commercial multispectral imaging systems such as RGB cameras to further enhance the spectral resolution. It can be adapted to different spectral ranges, depending on the application.

摘要： An optical assembly is disclosed including two laterally variable bandpass optical filters stacked at a fixed distance from each other, so that the upstream filter functions as a spatial filter for the downstream filter. The lateral displacement may cause a suppression of the oblique beam when transmission passbands at impinging locations of the oblique beam onto the upstream and downstream filters do not overlap. A photodetector array may be disposed downstream of the downstream filter. The optical assembly may be coupled via a variety of optical conduits or optical fibers for spectroscopic measurements of a flowing sample.

摘要： A multi-channel infrared spectrometer for detecting an infrared spectrum of light received from an object. The spectrometer comprises a wavelength converter system comprising a nonlinear material and having an input side and an output side. The wavelength converter system comprises at least a first up-conversion channel and a second up-conversion channel, and is arranged such that light traversing the wavelength converter system at different angles in the nonlinear material is imaged into different positions in an image plane. The first up-conversion channel is configurable for phase-matching infrared light in a first input wavelength range incident on the first side and light in a first output wavelength range output on the second side, and correspondingly, the second up-conversion channel is configurable for phase-matching infrared light in a second input wavelength range incident on the first side into light in a second output wavelength range output on the second side. The spectrometer further comprises a demultiplexer configured for demultiplexing light in the first up-conversion channel and light in the second up-conversion channel. The demultiplexer is located on the first side or the second side of the wavelength converter system. Finally, the spectrometer comprises a spatially resolved detector arranged in the image plane to detect light in the first output wavelength range and second output wavelength range output of the wavelength converter system.
