The device involves, for example, a special detection connection of photodetectors, a measuring unit and a basic module with a computer, the design of reflecting targets for liquid and solid samples, an optomechanical dimension transmitter and a holder of solid samples."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and apparatus for investigation of volume change dynamics of physiologically active samples","description":"A transversal change of the position of a measured sample surface exposed to the influence of visible radiation for example actinic light, is measured interferometrically by a reflecting target, which","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8520215","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
