“…A precise and reliable light measurement device needs an ensemble of electronic components to process and display optical power accurately. This can be achieved by including operational amplifiers (op-amp) for enhancing signal strength, analog-to-digital converters (ADC) to transform analog signals into digital data, voltage regulators to ensure a consistent power supply, and microcontrollers for data processing and system control [18,19]. Furthermore, such a circuit incorporates resistors and capacitors for stability and feedback mechanisms to refine the signal, collectively ensuring precise and reliable measurements.…”

This study introduces the design, construction, and evaluation of an affordable optical power meter prototype, AYR (Affordable Yet Reliable) version 1.0, which operates effectively within the 400-800 nm range, using a silicon photodiode. Aimed at bridging the gap in accessibility to precise and reliable photonics instrumentation, especially in resource-constrained settings, AYR 1.0 leverages advancements in photodiode technology, additive manufacturing, and do-it-yourself electronics. The device incorporates a custom-built electronic circuit that facilitates accurate optical power measurement by converting light into electrical current. Through rigorous testing against a reliable commercial optical power meter, AYR 1.0 demonstrated exceptional accuracy and reliability. Sensitivity values ranged from ~13 µA/mW at 405 nm to ~796 µA/mW at 805 nm. The operational power range spanned from 0.003 mW to 242.0 mW, with linearity (R²) values consistently above 0.9981, indicating high fidelity in measurement. Repeatability percentages varied between 99.4% and 99.9%, and response times ranged up to 55 µs, showcasing the prototype's rapid and reliable response to changes in optical power. The key components include a low-cost silicon photodiode (2DU10), a differential trans-impedance amplifier circuit for signal processing, and a 3D-printed housing for the sensor head and console, contributing to its cost-effectiveness and robustness. The prototype's total cost was 116 US dollars, highlighting its affordability and potential for widespread adoption.

ABSTRAKTulisan ini menjelaskan tentang pembuatan optical power meter (OPM) menggunakan Raspberry Pi sehingga disebut RPi OPM. Penelitian yang dilakukan meliputi perancangan rangkaian pengondisian sinyal dan sistem pengolahan data dengan Raspberry Pi. Pengondisi sinyal berupa transimpedansi amplifier dengan enam buah resistansi, yaitu 100 Ω, 1 kΩ, 10 kΩ, 100 kΩ, 1 MΩ, dan 10 MΩ sebagai pemilih jangkauan pengukuran daya optik. Di sisi lain, Raspberry Pi berfungsi sebagai pengolah data dan penampung hasil pengukuran. Percobaan menggunakan dua buah sumber cahaya, yaitu laser dioda dengan panjang gelombang 1.310 nm dan 1.552 nm.Hasil pengukuran RPi OPM dibandingkan dengan OPM Anritsu ML9002A sebagai validasi pembacaan. RPi OPM yang telah dibuat mampu mengukur daya optik pada rentang -50 dBm sampai -5 dBm untuk kedua panjang gelombang tersebut. Adapun eror pembacaan memiliki nilai terbesar 0,53 dBm dan terkecilnya 0,01 dBm pada saat mengukur daya laser dioda 1.310 nm, sedangkan 0,41 dBm dan 0,03 dBm saat pada saat mengukur laser dioda 1.552 nm. Kata kunci: optical power meter, pengondisian sinyal, pengolahan data, raspberry pi ABSTRACT This paper describes the design of optical power meter (OPM) with the Raspberry Pi that is so called
