Abstract: Disclosed are a dual-optical-path spectrophotometer and a color measurement method thereof. The spectrophotometer includes an integrating sphere, a light source, and a sensor. A second shutter, a semi-reflecting and semi-transmitting device and lenses are arranged between the detection hole and the sensor, and a light guide device and a first shutter are arranged between a light guide hole formed in the integrating sphere and the semi-reflecting and semi-transmitting device. The color measurement method includes the following steps. A first shutter is closed, a second shutter is opened, light, reflected by the measuring opening, enters a sensor and the sensor measures a spectral reflected signal of the object surface. The first shutter is opened, the second shutter is closed, reflected light enters the sensor, and the sensor measures a spectral reflected signal of a light source. A final sampled signal is calculated.

Abstract: Aspects of embodiments pertain to a sensing systems configured to receive scene electromagnetic (EM) radiation comprising a first wavelength (WL1) range and a second wavelength (WL2) range. The sensing system comprises at least one spectral filter configured to filter the received scene EM radiation to obtain EM radiation in the WL1 range and the WL2 ranges; and a self-adaptive electromagnetic (EM) energy attenuating structure. The self-adaptive EM energy attenuating structure may comprise material that includes nanosized particles which are configured such that high intensity EM radiation at the WL1 range incident onto a portion of the self-adaptive EM energy attenuating structure causes interband excitation of one or more electron-hole pairs, thereby enabling intraband transition in the portion of the self-adaptive EM energy attenuating structure by EM radiation in the WL2 range.

Abstract: 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.
