Abstract: Through-focus scanning optical microscopy (TSOM) is an economical, non-contact and nondestructive method for rapid measurement of three-dimensional nanostructures. There are two methods using TSOM image to measure the dimensions of one sample, including the library-matching… read more here.

DOI: 10.1117/1.oe.56.6.064103
Abstract: Abstract. We propose a laser trapping-based scanning dimensional measurement method for free-form surfaces. We previously developed a laser trapping-based microprobe for three-dimensional coordinate metrology. This probe performs two types of measurements: a tactile coordinate and… read more here.

DOI: 10.1364/oe.450740
Abstract: We propose a high-throughput and precise waveguide-dimensional-measurement method consisting of a generative adversarial network (GAN) and curve-fitting-based dimensional calculator using sidewall functions. The GAN can learn the differences between low-magnification (LM) and high-magnification (HM) optical… read more here.

DOI: 10.3938/jkps.72.863
Abstract: For three-dimensional microscopy, fast and high axial resolution are very important. Extending the depth of field for digital holographic is necessary for three-dimensional measurements of thick samples. We propose an optical sectioning method for optical… read more here.
