    Abstract: The invention can use different types of illumination sources to obtain radiation in the 250-1100nm wavelength range that includes a part of the visible, ultraviolet and infrared region of the electromagnetic spectrum, without the need for any external intervention, as a result of the moving illumination panels, the open frame stage, and the moving imaging system, It is related to a spectroscopic, hyperspectral and digital imaging device that provides the measurement of the energy of the light reflected from the surface of the object at different wavelengths by being homogeneously and strongly illuminated from all possible aspect and directions of the object subject to examination. The device in question basically includes; a movable floor table on which the object to be examined is placed and can be easily disassembled and installed thanks to the socketed structure of the vacuum module, which functions to fix the object to the floor and smooth its surface depending on the need, movable illumination panels that enable the use of different types of illumination sources for different wavelengths in the desired combination and number, and to adjust the angle of incidence of the light to the object to be examined at the time of examination with its mobility in horizontal and vertical axis; spectroscopic measurement module which contains the spectrometer optical fiber tips arranged in the probe tip are brought closer to the object surface to a distance of 1 mm to the surface of the object to be examined and positioned accurately to the target point to be measured by endoscopic cameras, thus enabling measurement with high accuracy and precision, free from interference effects and noise-free; colorful and monochrome camera modules, a lens system with high optical zooming capacity, a linear optical filter and a moving imaging system with motion mechanisms that ensure their alignment with each other. Spectral information of each pixel in images obtained using many narrow wavelength bands is processed using hyperspectral image analysis methods, pattern recognition algorithms, machine learning, and deep learning algorithms in a computer to which the device is connected, and extracting the desired information from the images, identifying and classifying the object and anomaly (contradiction) can be detected.

    Abstract: Systems and methods which provide a high-throughput point source light coupling structure (120) implementing a condenser (122) configured according to one or more condenser (122) configuration rules are described. Embodiments of a high-throughput point source light coupling structure (120) utilize a birefringent plate (341, 342) configuration in combination with a condenser (122) and point source (121) to provide a light coupler structure (120) for a birefringent-static-Fourier transform interferometer implementation. According to some examples, the optical axis of a first and second birefringent plate (341, 342) of a birefringent plate (341, 342) configuration are not in the same plane. The condenser (122) of the high-throughput point source light coupling structure (120) of embodiments is provided in a defined (e.g., spaced, relational, etc.) relationship with respect to the point source (121) and/or a camera lens (131) used in capturing an interference pattern generated by the light coupling structure (120). The high-throughput point source light coupling structure (120) herein may be provided as external accessories for processor-based mobile devices (130) having image capturing capabilities.

    Abstract: An optical system, comprising a multi-spectral optical element, a switchable filter, a dual bandpass filter, and a sensor. The multi-spectral optical element receives light in at least a first spectral band and a second spectral band. The dual bandpass filter filters out wavelengths of light in a transition region of the switchable filter between the first spectral band and the second spectral band. The switchable filter filters light received from the dual bandpass filter in the first spectral band in a first mode where the switchable filter transmits light in the first spectral band and in a second mode where the switchable filter does not transmit light in the first spectral band. The sensor is disposed at an image plane, and the multi-spectral optical element is configured to produce a modulation transfer function value that is a above a predetermined threshold for each of the spectral bands.

    Abstract: The present application relates to a system for performing time-resolved interferometric spectroscopy of incoming light. In some embodiments, the system includes one or more optical elements, a photo-detector, a capacitance detector, and one or more processors. Upon application of a varying input signal to the one or more optical elements, a change to an optical characteristic is caused resulting in a changing interference pattern produced by the incoming light incident on the one or more optical elements. During the application of the varying input signal, the photo-detector may detect an intensity of light output from the one or more optical elements and the capacitance detector may detect a capacitance of the one or more optical elements.
