Abstract: Provided is a reliable or accurate optical detection method or such an optical imaging method. Also provided is an application technique using such a method. At least a part of an optical path starting from a light-emitting source or reaching a photodetector includes a plurality of optical paths. At a predetermined position of the optical path, beams of light after passing through the plurality of optical paths are mixed. This mixed light is used for optical detection or optical imaging. An optical-length difference among beams of light passing through the plurality of optical paths may be longer than the coherence length. Means for feed-backing predetermined characteristics of a target to the optical characteristics to be used for optical detection or optical imaging may be included. Such means may be used separately from the above. Such means may be applied to another technique, an application material or an application program.

Abstract: A metrology apparatus (302) includes a higher harmonic generation (HHG) radiation source for generating (310) EUV radiation. Operation of the HHG source is monitored using a wavefront sensor (420) which comprises an aperture array (424, 702) and an image sensor (426). A grating (706) disperses the radiation passing through each aperture so that the image detector captures positions and intensities of higher diffraction orders for different spectral components and different locations across the beam. In this way, the wavefront sensor can be arranged to measure a wavefront tilt for multiple harmonics at each location in said array. In one embodiment, the apertures are divided into two subsets (A) and (B), the gratings (706) of each subset having a different direction of dispersion. The spectrally resolved wavefront information (430) is used in feedback control (432) to stabilize operation of the HGG source, and/or to improve accuracy of metrology results.

Abstract: A method of calibrating a hyperspectral imaging device includes illuminating a hyperspectral imaging sensor with a light source having known spectral properties, sampling the light from the light source with the hyperspectral imaging sensor to obtain sampled spectral properties, and calibrating a performance characteristic of the hyperspectral imaging sensor based upon comparing the sampled spectral properties of the light source to the known spectral properties.

Abstract: A smart phone or tablet includes laser diodes configured to be pulsed and generate near-infrared light between 700-2500 nanometers. Lenses direct the light to a sample. A detection system includes a photodiode array with pixels coupled to CMOS transistors, and is configured to receive light reflected from the sample, to be synchronized to the light from the laser diodes, and to perform a time-of-flight measurement of a time difference between light from the laser diodes and light reflected from the sample. The detection system is configured to convert light received while the laser diodes are off into a first signal, and light received while at least one laser diodes is on, which includes light reflected from the sample, into a second signal. The smart phone or tablet is configured to difference the first signal and the second signal and to generate a two-dimensional or three-dimensional image using the time-of-flight measurement.

Abstract: A forward-viewing spectrally encoded endoscope (SEE) probe includes a light guiding component, a light focusing component, and a grating component arranged along a longitudinal axis of a drive cable. The SEE probe is configured for guiding light from the light guiding component, through the light focusing component, and to the grating component, and then forwarding a spectrally dispersed light line from the grating component towards an image plane. One or more of the light guiding component, the light focusing component, and the grating component is arranged at an angle with respect to the longitudinal axis of the drive cable so that at least one wavelength of the spectrally dispersed light line goes to the direction of axis of the drive cable.
