Specifically, it has non-ionizing response which is able to penetrate through dielectric materials. Moreover, Terahertz sensitively detects chemical and explosive materials. According to those unique properties, countless research and development are conducted in this frequency range implemented extensively in many applications (eg., Non Destructive Testing (NDT) in industry, medicine, security scanning, and communication). In order to expand this knowledge area in Thailand, Terahertz Technology Team (TRT) is initiated to specifically conduct research and develop industrial section focused on country\u2019s mission. This research team will be one potentiality in international technology competition. In addition, our research team is also interested in applying Lidar technology for technology development groups related to Thailand\u2019s 20-year national strategy.<\/p><p><img

It can act as both the transmitter and the receiver upon the laser excitation. PCA is a semiconductor device that usually consists III-V photoconductive substrate and gold electrodes. We are working on the PCA design optimization by using the FEM based simulation software. At the same time, we are also working on the device fabrication, ranging from substrate development, PCA chips fabrication, and assembling PCA chips to peripheral necessary components to make them readily used by the end user.<\/p><p><img loading=\"lazy\" decoding=\"async\" class=\"size-full aligncenter\" src=\"https:\/\/www.nectec.or.th\/sectionImage\/9864\" width=\"650\" height=\"242\" \/><\/p><p><strong>4.

One fascinating property of terahertz is that many polar molecules, especially biomolecules, have fingerprints, i.e. a unique spectral absorption patterns in this region of the electromagnetic wave spectrum. With the fingerprint databank as references, terahertz spectroscopy can be applied in many fields, for example, specific chemical detection and quantification, pharmaceutical drug development, as well as facilitating basic research in molecular biology.<\/p><p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full aligncenter\" src=\"https:\/\/www.nectec.or.th\/sectionImage\/9866\" width=\"650\" height=\"365\" \/><\/p><p>6.

Such measurements can be used for site exploration and 3D map construction. The main component of this system consists of a LiDAR sensor, a GPS, an IMU, and a control unit. The acquired measurements can be processed to obtain height, tilt angles, distance between 2 points of interest, as well as latitude and longitude. Thanks to the light source used in LiDAR having short wavelength and frequency not in the visible light region, most LiDARs allow image resolution in the order of millimeters and can be operated during both day and night times.<\/p><p><img loading=\"lazy\" decoding=\"async\" class=\"size-full aligncenter\" src=\"https:\/\/www.nectec.or.th\/sectionImage\/9867\" width=\"650\" height=\"207\" \/><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-6d293aa elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"6d293aa\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-6d91f92\" data-id=\"6d91f92\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-326ab06 elementor-widget elementor-widget-heading\" data-id=\"326ab06\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-medium\">Members &amp; Expertise\u00a0<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-65c7887 elementor-widget elementor-widget-text-editor\" data-id=\"65c7887\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<ul><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Kiattiwut Prasertsuk, Ph.D. (Researcher)<\/strong>: Materials for Terahertz Engineering, Compound Semiconductor Physics, Micro &amp; Nano Semiconductor Fabrication Technology, Solid State Physics<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Rungroj Jintamethasawat, Ph.D. (Researcher)<\/strong>: THz imaging, Acoustic\/Optical Imaging and Tomography, Inverse Problems<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Patharakorn Rattanawan B.Eng.
