Use representative low-, medium-, and high-return surfaces at the wavelength of interest. Record target size and angle, window state, visibility, ambient condition, temperature, supply, update rate, and software configuration.<\/p>\n<p>A single successful reading is weak evidence. Run repeated trials and report the valid-return percentage, spread of valid measurements, false returns, and failure modes. Then test across the operating envelope that matters to your platform. This approach reveals whether the limit comes from energy, pointing, target interception, path attenuation, background light, receiver noise, or the acceptance logic.<\/p>\n<p>Lumexis develops <a href=\"https:\/\/lumexislaser.com\/ar\/1535nm-7km-laser-rangefinder-module\/\">\u0648\u062d\u062f\u0627\u062a \u0642\u064a\u0627\u0633 \u0645\u062f\u0649 \u0627\u0644\u0644\u064a\u0632\u0631<\/a> with in-house optical, electronic, firmware, weak-signal algorithm, and thermal-management capabilities.

Accuracy is the difference between a valid measurement and the true distance. A system may maintain good accuracy for detected returns while its valid-return rate falls as distance, target return, or visibility worsens.<\/p>\n<h3>Does a narrower beam always increase maximum range?<\/h3>\n<p>No. A narrower beam increases irradiance on a well-pointed target, but it also reduces pointing tolerance. Platform motion, boresight error, vibration, and small targets can make a narrow beam miss more often. Divergence must be chosen with target size and pointing performance.<\/p>\n<h3>Why can a rangefinder work farther at night?<\/h3>\n<p>Lower ambient light can reduce the optical background reaching the detector, increasing the margin between a weak return and the noise-dependent threshold. The improvement depends on receiver field of view, spectral filtering, detector behavior, and processing; it is not a fixed multiplier.<\/p>\n<h3>Can averaging always extend range?<\/h3>\n<p>Averaging or integrating multiple returns can improve sensitivity when the signal is repeatable, but it reduces update rate and may fail when the platform or target moves too much during the integration period. Compare range and rate together.<\/p>\n<h3>What target reflectivity should a range specification use?<\/h3>\n<p>There is no single value that represents every application. Define reflectance at the operating wavelength and choose targets that bracket the expected field surfaces. The specification should also state target size, angle, beam interception, atmosphere, ambient light, and the required valid-return rate.<\/p>\n<p>If you are defining a new system, <a href=\"https:\/\/lumexislaser.com\/ar\/contact\/\">send us<\/a> the target type and size, required range and update rate, wavelength preference, optical window, mechanical envelope, interface, temperature range, and platform motion. Our team can review the signal-budget assumptions, recommend a standard module where it fits, or scope a custom or private-label configuration. Standard products can ship within three days; custom lead time is confirmed against the project.<\/p>\n<h2>\u0627\u0644\u0645\u0631\u0627\u062c\u0639<\/h2>\n<ol>\n<li>RIEGL, <a href=\"https:\/\/www.riegl-japan.co.jp\/product\/pdf_1\/General-Information-Distancemeter.pdf\" target=\"_blank\" rel=\"noopener\">Operation of a Pulsed Laser Distance Meter<\/a>.<\/li>\n<li>Ma et al., <a href=\"https:\/\/doi.org\/10.3390\/s22062146\" target=\"_blank\" rel=\"noopener\">The Short-Range, High-Accuracy Compact Pulsed Laser Ranging System<\/a>, <em>Sensors<\/em> 22, 2146 (2022).<\/li>\n<li>RIEGL, <a href=\"https:\/\/www.riegl.com\/fileadmin\/media\/Products\/06_Industrial_Scanning\/Laser_Distance_Meters\/10_DataSheet_LD05-A10GF_2024-02-28.pdf\" target=\"_blank\" rel=\"noopener\">LD05-A10GF Technical Data<\/a>.<\/li>\n<li>NIST, <a href=\"https:\/\/www.nist.gov\/pml\/sensor-science\/dimensional-metrology\/ranging-tests-laser-scanners\" target=\"_blank\" rel=\"noopener\">Ranging Tests for Laser Scanners<\/a>.<\/li>\n<\/ol>","protected":false},"excerpt":{"rendered":"<p>\u0627\u0644\u0645\u062f\u0649 \u0627\u0644\u0623\u0642\u0635\u0649 \u0644\u062c\u0647\u0627\u0632 \u0642\u064a\u0627\u0633 \u0627\u0644\u0645\u0633\u0627\u0641\u0629 \u0628\u0627\u0644\u0644\u064a\u0632\u0631 \u064a\u0639\u062a\u0645\u062f \u0639\u0644\u0649 \u0627\u0644\u0645\u0631\u0633\u0644\u060c \u0627\u0644\u0647\u062f\u0641\u060c \u0627\u0644\u063a\u0644\u0627\u0641 \u0627\u0644\u062c\u0648\u064a\u060c \u0627\u0644\u0645\u0633\u062a\u0642\u0628\u0644\u060c \u0648\u0627\u0644\u0645\u0639\u0627\u0644\u062c\u0629. \u062a\u0639\u0644\u0645 \u0643\u064a\u0641\u064a\u0629 \u0645\u0642\u0627\u0631\u0646\u0629 \u0627\u0644\u0627\u062f\u0639\u0627\u0621\u0627\u062a \u0628\u0634\u0643\u0644 \u0639\u0627\u062f\u0644.<\/p>","protected":false},"author":3,"featured_media":1972,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[29],"tags":[32,46],"class_list":["post-1977","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-laser-basic-knowledge-101","tag-laser-parameters","tag-laser-ranging"],"acf":[],"_links":{"self":[{"href":"https:\/\/lumexislaser.com\/ar\/wp-json\/wp\/v2\/posts\/1977","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lumexislaser.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/lumexislaser.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/lumexislaser.com\/ar\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/lumexislaser.com\/ar\/wp-json\/wp\/v2\/comments?post=1977"}],"version-history":[{"count":1,"href":"https:\/\/lumexislaser.com\/ar\/wp-json\/wp\/v2\/posts\/1977\/revisions"}],"predecessor-version":[{"id":1978,"href":"https:\/\/lumexislaser.com\/ar\/wp-json\/wp\/v2\/posts\/1977\/revisions\/1978"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/lumexislaser.com\/ar\/wp-json\/wp\/v2\/media\/1972"}],"wp:attachment":[{"href":"https:\/\/lumexislaser.com\/ar\/wp-json\/wp\/v2\/media?parent=1977"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/lumexislaser.com\/ar\/wp-json\/wp\/v2\/categories?post=1977"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/lumexislaser.com\/ar\/wp-json\/wp\/v2\/tags?post=1977"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
