“…Gao et al [13] utilized the least square method to fit cam curves using the Zemax programming language. Zhang et al [14] proposed a method for analyzing and simulating the geometric characteristics of fit surfaces in globular cam mechanisms. They illustrated their approach using a globular cam mechanism in an automatic tool-changing device for CNC(Computer Numerical Control) machine tools.…”

A cam design method is proposed in this study that utilizes mathematical modeling and MATLAB simulation analysis. The objective is to construct cam profiles that are suitable for complex trajectories with precision and efficiency. Initially, mathematical modeling is employed to determine the projected running trajectory. Subsequently, the corresponding cam contour is derived through MATLAB simulation analysis. To demonstrate the effectiveness of the proposed method, a carbon-free car navigating a complex path is chosen as an illustrative example for cam design. Experimental results confirm that the car successfully follows the predetermined path using the cam steering mechanism, with the walking trajectory closely aligning with the preset trajectory. This outcome substantiates the reliability of the cam design method.

“…The removing secondary spectrum method considering the three kinds of wavelength (656.3 nm, 486.1 nm and 589.3 nm) have advantage over traditional achromatic technology (656.3 nm and 486.1 nm) and it can obtain wide spectrum and high imaging quality. The modulated transfer function (MTF) of this system has been simulated by ZEMAX software [27] at the imaging plane and results are shown in figure 3.…”

The analysis of fast physical phenomena is a relevant tool in several fields including atomic physics and photochemistry. In turn, to record phenomena occurring on an ultra-short time scale, one needs an imaging system that can accurately capture the event. In this paper, we propose a novel ultrafast optical framing camera that achieves a spatial resolution up to 36.6 LP/mm while keeping a high temporal resolution of 3.25 ns using a digital delay generator. Our technique involves the splitting of light into four beams and their imaging on four ICCD cameras. In addition, the data transfer system is designed to combine data-streams from multiple digital ports into a single output, thus providing a compact user interface. The characteristic parameters influencing the temporal resolution of the image intensifier has been analyzed, and the framing camera has been experimentally assessed. Our results show that a temporal resolution of 3.25 ns and a spatial resolution of 36.6 LP/mm can be obtained. We foresee the use of our apparatus for inertial confined fusion.

Öz: Optik, elektro-optik ve optomekanik bileşenler kullanılarak izlenmek istenen hedeflerin görüntülenmesi için oluşturulan sistemler optik görüntüleme sistemleri olarak adlandırılmaktadır. Farklı menzillerde bulunan hedefi net bir şekilde görüntülemek için değişken odaklı (zoom) optik görüntüleme sistemleri kullanılmaktadır. 'Zoom sistemleri' olarak da bilinen bu sistemlerin görüntü alabilmesi için objektifte bulunan mercek gruplarının bazılarının doğrusal olarak hareket etmesi gerekir. Bu hareket elle ya da motor yardımı ile sağlanabilir. Hareketli mercek grupları içerdikleri ve hassas konum kontrolü gerektirdiği için bu sistemlerin optik ve mekanik tasarımı zordur. Bu çalışmada değişken odaklı görüntüleme sistemleri hakkında genel bilgiler verilerek, sistemi oluşturan en uygun mekanizma tipine karar verilip sistemin tasarımı ve üretimi gerçekleştirilmiştir. Son olarak üretilen sistem tasarımsal olarak doğrulanmıştır Anahtar kelimeler: Optik görüntüleme sistemi, Değişken odak sistemi, Zoom sistemi, Tasarım ve üretim.Abstract: Optical imaging systems are used to visualize the targets to be monitored using optical, electro-optic and optomechanical components. Variable-focus (zoom) optical imaging systems are used to clearly display the target at different ranges. These systems, also known as 'zoom systems', require some of the lens groups in the lens to move linearly in order to capture images. We can provide this motion by hand or by motor. The optical and mechanical design of these systems is difficult as they contain moving lens groups and require precise position control. In this article, by giving general information about variable focus imaging systems, the most appropriate mechanism forming the system is decided and the design and production of the system has been realized. The designed system has been verified produced system.
