The invention relates to a large-zoom ratio automatic focusing integrated camera, which belongs to the field of optical, mechanical and electronic integration. The camera comprises an automatic focusing system, a video drive system and a shell thereof. The camera adopts a contrast detection method to carry out automatic focusing, and a processor (108) of the automatic focusing system is utilized to send out control signals to acquire, process, calculate and compare image signals and processing signals to control a step motor (111) to drive a compensation assembly (G4) to move to a focusing position, so that the camera is automatically focused. The automatic focusing of the camera does not need an auxiliary light source, and cannot be affected by the distance of an object, the focusing process is controlled by the microprocessor, the time is short, the camera also has the function of video drive, and can automatically adjust an aperture according to environments, so the camera can be accurately, quickly and automatically focused under various environments, while the image cannot be distorted, and the camera can be widely applied to fields, such as expressways, air ports, finance, military, ports and the like.

The invention relates to a high-sensitivity grating ruler with stepped photoelectric sensor arrays. The grating ruler comprises a plane light source, an optical lens, a scale gating and photoelectric sensor arrays. The optical lens, the scale gating and the photoelectric sensor arrays are perpendicular to the irradiation direction of the plane light source and successively arranged along the irradiation direction of the plane light source. The photoelectric sensor arrays are arranged in a stepped manner in the width direction of the grating ruler. The photoelectric sensors in the photoelectric sensor arrays are separated from each other one by one. The grating ruler is quick in measurement speed and high in precision. Signal sensitivity of the sensors is high, image processing is not required, pulse sequences with the consistent phase position difference are acquired, pulse quantity and directions are quickly acquired and rapid processing of displacement information is achieved.

The invention belongs to a photosensitive sensor, and particularly relates to a CCD (Charge Coupled Device) sensor. A multi-mode super CCD (Charge Coupled Device) sensor is characterized by comprising multiple lines of single-linear-array CCDs and an addressing circuit, wherein lines of the multiple lines of single-linear-array CCD are arranged closely; the addressing circuit is connected with the driving pulse signal of each line of single-linear-array CCDs; and each line of single-linear-array CCDs is provided with an independently determined address which is selected through a driving address gating signal. The multi-mode super CCD sensor has the function of an area array CCD for acquiring two-dimensional images signals. Moreover, the imaging time and charge transfer time of each line of imaging units can be controlled and output separately, and single-linear-array scanned image sequences are generated respectively.

This invention is a CCD image sensor and its measurement device and method. The sensor is composed of multiple crossed photoelectron diodes, each of which has relative one row of charge transfer device 2 connected with the photoelectron diode row through reading the grating. The measurement method is to put the subject to be measured between the optics lens and sensor and to measure the total length between the light-emitting diodes without apparent light sensitivity due to the subject blinding to compute the subject length.
