摘要： A hyperspectral camera system includes an input optical assembly, a lenslet array, a dispersion element, and an image sensor. The input optical assembly magnifies an image of a sample onto an image plane. The lenslet array is positioned approximately at the image plane and includes a 2D array of microlenses that concentrate the image into an array of image portions. Each of the image portions has a smaller area than a corresponding one of the microlenses and the image portions are at least partially separated from each other by interstitial regions. The dispersion element is disposed in the optical path of the image to spatially disperse spectral components in each of the image portions to generate spectrum stripes that spatially spread different spectral components of the image sourced from a single sample location within the sample. The image sensor captures a snapshot image of the spectrum stripes.

摘要： A single snapshot multi-frequency demodulation method for a modulated image obtained by modulating and summing one or more original components at different frequencies in a time domain or spatial domain, especially for a modulated image including multiple frequency components. AC and DC component values of each pixel at each frequency are extracted sequentially, and then an original AC and DC component image corresponding to each frequency is obtained. The method can be used in the time or spatial domain, can decompose multiple frequency component images using single measurement, has the advantages of fast speed, higher demodulation precision and good de-noising effect, meets the requirements for acquiring multiple pieces of frequency information at a time and overcomes inevitable errors in multiple measurements. Further, multiple pieces of image information can also be transmitted once using the demodulation method, so that parallel real-time transmission of the information in the communication field is realized.

摘要： An image sensor includes a substrate, a first set of sensor pixels formed on the substrate, and a second set of sensor pixels formed on the substrate. The sensor pixels of the first set are arranged in rows and columns and are configured to detect light within a first range of wavelengths (e.g., white light). The sensor pixels of the second set are arranged in rows and columns and are each configured to detect light within one of a set of ranges of wavelengths (e.g., red, green, and blue). Each range of wavelengths of the set of ranges of wavelengths is a subrange of said first range of wavelengths, and each pixel of the second set of pixels is smaller than each pixel of the first set of pixels.

摘要： A biological information detection device includes a light source, an image capturing device, and one or more arithmetic circuits. The light source projects dots formed by light onto a target including a living body. The image capturing device includes photodetector cells and generates an image signal representing an image of the target onto which the dots are projected. The one or more arithmetic circuits detect a portion corresponding to at least a part of the living body in the image by using the image signal and calculate biological information of the living body by using image signal of the portion.

摘要： An image pickup apparatus includes an objective optical system, an image pickup element having a surface at an image formed by the objective optical system, and an etalon positioned between the objective optical system and the surface of the image pickup element. The etalon includes a gap, an optical path length of which is controllable for scanning the wavelengths transmitted by the etalon to thereby select the wavelengths that reach the surface. An optical filter is positioned between the objective optical system and the surface and has a first wavelength range over which incident light is reflected, a second wavelength range over which incident light is transmitted, and a boundary wavelength range that is bounded by the first and second wavelength ranges. The boundary wavelength range lies entirely within the wavelength range the peak transmission of the etalon can be scanned. A method of calibrating the etalon is also disclosed.
