“…The maturity of silicon focal plane array (FPA) camera sensors, coupled with advances in smartphone technology affords significant developments in handheld scientific instrumentation [18]. Smartphones can be easily adopted as platforms for prototype and commercial instruments in a wide variety of scientific fields due to the fast on-board computing power and built-in sensors [9,[19][20][21][22][23][24][25][26][27]. In a previous publication, a smartphone-based hyperspectral imaging device was reported and demonstrated as a viable, low-cost alternative to more expensive lab-based systems [9].…”

Image Correction and In Situ Spectral Calibration for Low-Cost, Smartphone Hyperspectral Imaging

Developments in the portability of low-cost hyperspectral imaging instruments translate to significant benefits to agricultural industries and environmental monitoring applications. These advances can be further explicated by removing the need for complex post-processing and calibration. We propose a method for substantially increasing the utility of portable hyperspectral imaging. Vertical and horizontal spatial distortions introduced into images by ‘operator shake’ are corrected by an in-scene reference card with two spatial references. In situ light-source-independent spectral calibration is performed. This is achieved by a comparison of the ground-truth spectral reflectance of an in-scene red–green–blue target to the uncalibrated output of the hyperspectral data. Finally, bias introduced into the hyperspectral images due to the non-flat spectral output of the illumination is removed. This allows for low-skilled operation of a truly handheld, low-cost hyperspectral imager for agriculture, environmental monitoring, or other visible hyperspectral imaging applications.

We designed and tested a personalized home-kit that was distributed to students in a Physics Education course during the pandemic as part of the COSID-20 project. A goal of the design of the kit was to be inexpensive enough to be attractive to schools and universities: a collaboration with a local start-up has proven very valuable in this sense. In this work we will present our kit, discussing how to be able to perform many different experiments with low-cost, easy to find materials and tools.

Using smartphones to explore the physical laws of musical instruments is not only scientifically intriguing but also practically feasible. Here an experimental scheme based on a smartphone and mobile application (Phyphox) is devised to investigate the vibration law of guitar strings. By quantitatively measuring the length, diameter and vibration frequency of guitar strings, the experimental results convincingly demonstrate the validity of the vibration law of guitar strings. The research embodies the concept of ‘from life to physics, from physics to society’, and is beneficial for students to comprehend the physical laws of guitar string vibration as well as the principle behind guitar sounds. The smartphone-based physics experiments can be performed outside the classic physics laboratory, which expands the methods and space of teaching physics experiments, and relates reality to physics laws.
