Special Issue Information

Dear Colleagues,

Optical devices/components/coatings are key parts that determine the performance of high-end equipment in the fields of aerospace, national defense and military, and advanced civilian applications. Typical applications include high-resolution earth observation systems, aircraft optical seekers, large astronomical telescopes, X-ray telescopes, ultraviolet/extreme ultraviolet lithography machines, precision inertial devices, consumer electronics, medical equipment, and other equipment. The continuous improvement in the service capability of major equipment puts forward higher requirements for the performance of optical devices/components/coatings. For example, in the field of semiconductor chip manufacturing, extreme ultraviolet lithography technology is key for the international semiconductor industry to continue Moore's Law and ensure that the lithography resolution enters the 7 nm node. The extreme ultraviolet lithography objective lens needs to adapt to a series of stringent requirements represented by full-band and sub-nanometer precision manufacturing to ensure lithography performance. Optical devices/components/coatings find exciting applications in a vast range of fields, from physics, material science, and life science to industrial development.

This Special Issue aims to collect both review papers and original research articles in the field of optical devices/components/coatings for both fundamental and applied aspects. Theoretical and experimental papers and reviews will all be considered for publication. In addition, the topics to be covered in the Special Issue include, but are not limited to, the following: functional micro/nano structures, functional optical coatings, infrared/terahertz/microwave metamaterials/metasurfaces, flexible optical components, intelligent sensing components, photonics crystals, electromagnetic functional devices, precision measurement devices, optical measurement/metrology methods, multi-function measurement devices and systems, multi-degree of freedom measurement devices and systems, sensors, etc.

Considering that structured light depth imagers are difficult to use for precision measurements due to their limited measurement accuracy, we propose an innovative method for correcting structural parameters of structured light depth imagers to reduce the depth measurement error caused by structural parameter errors. For the structured light depth imager, the analytical imaging model is established, and the model of depth error caused by structural parameter errors is established based on the analysis of the depth measurement error analysis. Then, structural parameters are corrected according to the depth measurement error analysis and processing based on experimental depth imaging data of the standard reference plane at the maximum depth. As a result, the corrected analytical imaging model and corrected depth measurement values are obtained. Experimental results have demonstrated the success of this proposed method and its simplicity and convenience. Full article

The wide application of displacement measurement in high-precision equipment production and high-precision metrology is placing increasing pressure on the resolution of heterodyne interferometers. However, as the core component of an interferometer, since measurement electronics includes the cross-physical process of photoelectric conversion, its resolution is rarely evaluated, either on an individual level or as a whole. Therefore, in this paper, we propose a picometer resolution test method for measurement electronics, that uses intensity modulation signals based on an AOM to replace the beat frequency interference signals, and an ordinary commercial guide rail to equivalently generate the pm-level displacement of the heterodyne interferometer under laboratory conditions. Based on the detailed analysis of the type of noise in the test device, the correlation between the light intensity and the nonlinear error was established, and nonlinearity was suppressed to 10% of the original level. Furthermore, this test method allows one to perform a 0.1 mrad phase step test at 1 MHz signal frequency, equivalent to a 2.5 pm resolution test in a double-pass heterodyne interferometer. Simultaneously, it can be directly applied to the resolution test for measurement electronics with a center frequency in the range of 1 MHz to 20 MHz. Full article

The characterization of scanning tip morphology is crucial for accurate linewidth measurements. Conventional rectangular characterizers are affected by lateral distortion caused by the nonlinearities in AFM scanning, leading to errors between the actual characterization results and the true values. In this study, we innovatively developed self-traceable two-dimensional nano-gratings using chromium atomic deposition technology and extreme ultraviolet interference lithography. We used this structure as a characterizer for conducting scanning tip characterizations.This paper analyzed the periodic stability of the grating sample during scanning and corrected the lateral distortion of atomic force microscopy (AFM) at scan scales of 0.5 µm and 1 µm based on its self-traceable characteristics. Additionally, we extracted the angle information of the scanning tip in the X direction and Y direction within a scan scale of 0.5 µm. The results demonstrate that the two-dimensional grating sample exhibited excellent periodic stability during scanning. The characterization errors for the tip’s X direction and Y direction angles are within ±2°, showing high consistency. This study highlights that self-traceable two-dimensional grating samples have the capability for in situ bidirectional characterization of tip information, providing a creative solution for the development of new-style tip characterizers.

In view of the limitations of the existing eccentricity error separation method of the rotary table, an eccentricity error separation method based on the phase feature of the moiré signal of a single reading head is proposed herein. A grating pair transmission model is established based on the analysis of the principle of the rotary table; thereby, the influence of eccentricity error on the phase feature of the moiré signal in the rotation course of the rotary table is clarified, and the corresponding model between the phase feature spectral components and the eccentricity error is established. The verification experiments of the proposed method are carried out based on the laboratory-made circuit system. After verifying the accuracy of the data acquisition of the laboratory-made circuit board, the verification experiments of the eccentricity error separation effect of the proposed method are carried out. The experimental data are compared with those of the traditional method, and the results show that the error between the two methods is 2.34 μm, while the relative error is 2.3%. Full article
