The invention discloses a method for calculating the oil content of oil shale. The method comprises: obtaining the percentage contents of S element and Al element in the oil shale sample based on the oil shale sample; The oil shale oil content data measured by the laboratory of the oil shale mining area where it is located is obtained through multiple regression analysis to obtain calculation coefficients and establish the oil shale oil content regression equation; M=a+bC S +cC Al , where M is the oil content of oil shale, C s and C Al are the percentage content of S element and Al element respectively, a, b, and c are calculation coefficients; based on the percentage content of the S element and Al element and the oil shale oil content regression equation, the oil shale oil content is obtained . The method provided by the present invention can realize the rapid calculation of the oil content of the oil shale through the obtained percentage content of the S element and the Al element and the regression equation of the oil content of the oil shale.

The invention relates to a device for obtaining the width of a Moire fringe by using an image processing technology. The device comprises a device for acquiring an image of the Moire fringe, a device for obtaining the direction of the Moire fringe and a device for calculating the width of the Moire fringe, wherein the device for obtaining the direction of the Moire fringe defines a group of straight lines aj which are intersected into the same point on the image of the Moire fringe, obtains image gray value root mean square errors sigma j in the direction of the straight lines alpha j by using pixel values xij of each point on the image of the Moire fringe at positions where the straight lines aj pass, and uses a straight line au which corresponds to the minimum image gray value root meansquare error sigma u in the sigma j as the direction of the Moire fringe. According to gray values of pixel points on the image of the Moire fringe which is acquired by a computer, the device provided by the invention automatically identifies a direction angle of the Moire fringe, calculates the width of the Moire fringe, is high in calculation speed and high in accuracy, and can be widely applied to the fields of small-angle accurate measurement, photoelectric displacement accurate measurement and the like.

A lens mechanism, a lens cover and a lens group using the same. The lens cap selectively covers the lens mechanism. The lens mechanism includes a casing and a sleeve. The housing has a first chamfered surface, and an extension surface of the first chamfered surface obliquely intersects with the optical axis. The sleeve is arranged in the casing. The lens cover includes a base and a movable part. The movable part is movably arranged on the base relative to the base along the radial direction and has a second chamfered surface. The extension surface of the second chamfered surface obliquely intersects with the optical axis. When the lens cover covers the lens mechanism, the second angled surface is in contact with the first angled surface. Since the geometric contours of the first angled surface and the second angled surface match, the contact area between the first angled surface and the second angled surface increases. When the sleeve pushes the base along the optical axis, the second angled surface is separated from the first angled surface along the radial direction and the optical axis direction.

The invention discloses an optical fingerprint sensing device with a biomedical sensing function, and the device mainly comprises at least one light-emitting element which generates a light source, and an image sensing module. The image sensing module is provided with a plurality of sensing units, can receive the light reflected by fingers in a normal fingerprint sensing mode, and can transmit a measured brightness signal to the outside so as to obtain a fingerprint image. The image sensing module is provided with a local region, thereby enabling some sensing units of the plurality of sensingunits to be located in the local region at the same time. Moreover, the sensing units located in the local region form electrical connection through a first switch, so as to perform a biomedical sensing mode for measuring the light intensity signal of fingers. In addition, the time domain change of the light intensity signal is taken as a light volume description (PGG) signal for the subsequent biomedical application.
