Can you measure light with a mobile phone? One-click precise measurement, instantly understand the light environment
在这个光与影交织的世界里,光的本质——光谱,正悄然改变着我们的生活。从通用照明到显示技术,从汽车照明到元宇宙,光谱技术以其独特的魅力,渗透到每一个与光相关的领域。而在这个光的应用日益精细化的时代,人类每天接收的光信息量已达工业化前的300倍。哈佛医学院研究显示,现代人日均接触人工光源时长超过14小时,其中非自然光谱暴露引发的昼夜节律紊乱、视觉疲劳等问题,正以每年7%的速度递增。
A tool capable of precisely measuring and evaluating the light environment is particularly important. Facing this complex challenge, Professor Yao Qi's team at Fudan University has developed a product that integrates technology and innovation— Spectrum + Imaging Luminance Meter .

光的智慧,从光谱开始 The essence of light is the spectrum; it is not only the carrier of vision but also a key factor affecting human health and ecological balance. However, when the application of light evolves from 'visible' to 'comfortable to see and healthy to use', traditional light environment assessment methods can no longer meet modern needs. Traditional assessment methods mainly rely on single luminance or illuminance measurements, such as using point luminance meters or illuminance meters to assess light intensity. Although these methods can provide basic light intensity information, they have obvious shortcomings in assessing the health effects of light, circadian rhythm regulation, and blue light ratio. In addition, traditional methods make it difficult to quickly obtain large-area luminance distribution and cannot measure spectral information simultaneously. In contrast, the spectrum + imaging luminance meter breaks through technical barriers, transforming the complex concept of 'light dose' into intuitive data. Unlike common devices on the market, it requires no professional operation, nor complex equipment or tedious data processing. Users can accurately measure environmental luminance distribution, analyze blue light ratios, assess circadian rhythm impacts, and even quantify the ecological footprint of light pollution simply by using their smartphone camera. Whether natural light, display screen light, or urban nightscape lighting, the spectrum + imaging luminance meter can parse it with one click, making healthy light environments 'data-driven'. One-click precise light measurement, understand the light environment in seconds As an application designed specifically for smartphones, Spectrum+ Imaging Luminance Meter breaks the limitations of traditional devices, achieving high-precision luminance measurement using only a smartphone camera. Whether it is reading light in an office, lighting layouts in city nightscapes, or blue light distribution on displays, users can simply tap the screen to instantly obtain data on illuminance intensity and distribution. Its core algorithm integrates international lighting standards with over a decade of team research results, transforming complex spectral analysis into intuitive false-color maps and quantitative scores, making professional testing accessible to everyone. Comprehensive functionality meets diverse needs The Spectrum+ Imaging Luminance Meter is widely applicable in both professional fields and daily life. In professional settings, it helps urban planners, environmental scientists, and others quickly locate high-risk areas of light pollution in cities and conduct in-depth studies on the lighting impact of specific ecological zones; in daily life, home users can use it to check whether their home lighting environment meets standards and optimize indoor lighting. It not only measures ambient brightness in real time but also performs advanced functions such as light pollution analysis and feedback, high-risk area labeling, and intelligent evaluation systems, providing precise and convenient light environment assessment and optimization support for different user groups. Real-time Luminance Measurement: Simply open the app, point it at the area you want to measure, and get an instant luminance reading. Whether outdoors or indoors, quickly and accurately understand the current ambient light intensity and distribution. Light Pollution Analysis and Feedback: Supports instant photo capture or uploading existing images; the app automatically calculates the light intensity distribution within the image and analyzes its impact on human circadian rhythm, potential effects on biodiversity, and possible carbon footprint. Results are presented as false-color maps for intuitive understanding. High-Risk Area Marking: Built-in international lighting standards enable intelligent identification and marking of potential light pollution problem points, helping users easily identify areas needing improvement. Intelligent Evaluation System : Based on collected data, the system automatically provides a lighting quality score for the scene, allowing users to instantly see whether current lighting conditions meet health and comfort standards. User-Friendly Interaction : Allows users to freely select parts of interest for detailed analysis, meeting the needs of different users. Whether professionals or ordinary users, everyone can get started easily. One-Click Report Generation : No matter where you are, just tap the screen to quickly generate a professional report containing all analysis results, convenient for archiving or sharing with others. Currently, to continuously enhance the user experience, the Spectrum + Imaging Luminance Meter has been upgraded to version 2.0. The new version optimizes the APP function windows, simplifies the function menu, enhances scene shooting capabilities, and adds scene illumination luminance analysis functionality. At the same time, the report style has also been updated to be more aesthetically pleasing and easier to read. These upgrades allow the Spectrum + Imaging Luminance Meter to further improve user convenience and satisfaction while maintaining its original advantages.
