“…There are various ways to analyze the performance of the optical systems, such as aberration, spot diagram, illumination distribution, modulation transfer, encircled energy, and Strehl ratio [17,18]. In this paper, the aberration characteristic of the system comprised of spherical and cylindrical lenses is analyzed in terms of aberration ray fan plot curve, footprint diagram, and illumination distribution in ZEMAX [16].…”

Optical computing is a new method to implement signal processing functions. The multiplication between a vector and a matrix is an important arithmetic algorithm in the signal processing domain. The optical vector-matrix multiplier (OVMM) is an optoelectronic system to carry out this operation, which consists of an electronic module and an optical module. In this paper, we propose an optical module for OVMM. To eliminate the cross talk and make full use of the optical elements, an elaborately designed structure that involves spherical lenses and cylindrical lenses is utilized in this optical system. The optical design software package ZEMAX is used to optimize the parameters and simulate the whole system. Finally, experimental data is obtained through experiments to evaluate the overall performance of the system. The results of both simulation and experiment indicate that the system constructed can implement the multiplication between a matrix with dimensions of 16 by 16 and a vector with a dimension of 16 successfully.

“…With the experimental constraints taken into consideration, the earlier optical design [19] was modified. In our earlier work, the performance of the designed scanning system was evaluated for 25.4, 51.7 and 103.4 mm ROC mirrors with a 200 nm spectral bandwidth.…”

“…With the ability to miniaturize the proposed scanning system, this can have an impact in endoscopic imaging applications in particular. In our earlier work [19,20], a mathematical model and an optical design of a line scanning system was reported for 200 nm spectral bandwidth. The imaging performance was compared between a plano-convex cylindrical lens, an achromatic cylindrical lens, and a cylindrical mirror-based focused line scanning system with 50.8, 25.4, and 12.7 mm effective focal lengths [19].…”

An ultra-broad bandwidth light source is utilized in optical coherence tomography (OCT) for an ultra-high axial resolution. A lens focused scanning system is commonly used in the OCT imaging. The effective focal length of the lens varies as a function of the wavelength and hence it focuses a broadband spectrum in different focal planes. This variation eventually reduces the axial resolution of the OCT imaging. These variations become even more significant at a higher transverse resolution. In the present paper, a cylindrical mirror focused line scanning system for high quality imaging is presented. The imaging quality of the developed system was evaluated using optical design software and tested experimentally with 50.8 and 25.4 mm focal length cylindrical mirrors. A broadband light source with a center wavelength of 843 nm and a spectral bandwidth of 53 nm was used. The scanning system meets the Marechal criterion by providing a high Strehl ratio (SR) within the 2 mm target scan range. Moreover, the developed cylindrical mirror focused scanning is robust and insensitive to minor beam path variations, and this was proved experimentally.
