As previous processing of measurement in which gas to be measured containing, as gas components, carbon dioxide ¹³CO₂ and carbon dioxide ¹²CO₂, is introduced into a cell, and in which the intensities of transmitted lights having wavelengths suitable for measurement of the respective gas components, are measured and then data-processed to measure the concentrations of the gas components, the air having a predetermined volume Va is sucked by a gas injection device 21, a gas exhaust valve V6 of a cell 11 is closed and the air stored in the gas injection device 21 is transferred to the cell 11 filled with the air at an atmospheric pressure, thereby to pressurize the cell inside. The pressure thus pressurized is measured as P. The cell volume Vc is subtracted from the product obtained by multiplying the sum. V0 of the volume Va and Vc the cell volume Vc, by the ratio P0/P in which P0 is the target pressure of the gas to be measured at which a calibration curve has been prepared for an isotope gas analysis and measurement, thus determining the one-time gas injection amount of the gas injection device 21. Thus, measured concentration variations based on changes in atmospheric pressure can be corrected.

Systems and methods are described for providing a 3D display, such as a light-field display. In some embodiments, a display device includes a light-emitting layer that includes a plurality of separately-controllable pixels. An optical layer overlays the light-emitting layer. The optical layer includes a plurality of mosaic cells arranged in a two-dimensional array (e.g., a tessellation). Each mosaic cell includes a plurality of optical tiles. Different tiles may differ from one another in optical power, tilt direction, translucency, or other optical property. A spatial light modulator provides control over which optical tiles transmit light from the light-emitting layer outside the display device. The light-emitting layer and the spatial light modulator are controlled in a synchronized manner to display a desired pattern of light.

The disclosure provides a portable photometer capable of adjusting an ultra-long absorption optical path and a measuring method thereof. The portable photometer comprises an excitation light source, acolorimetric pool, reflecting mirrors, an auxiliary reflecting mirror and a light collector. The excitation light source is arranged at one end of the colorimetric pool and the light collector is arranged at the other end of the colorimetric pool; and the reflecting mirrors are arranged at the two sides of a colorimetric pool area between the two ends, so that parallel monochromatic light emittedby the excitation light source is reflected and propagated in the extending direction of the colorimetric pool. The colorimetric pool is arranged in parallel with a fixing piece; the fixing piece isused for fixing a smart phone; the arrangement position of the light collector corresponds to a light sensor of the smart phone, so that final transmission light can reach the light sensor through thelight collector. The auxiliary reflecting mirror is arranged at the tail end of the colorimetric pool and, together with the light collector, can guide and collect a light beam deviating in 2N reflection direction to the light sensor. Therefore, the detection sensitivity and accuracy of photometric analysis can be improved and the portability of the device is not obviously reduced.
