History

This is the history of learning the classic theory of pyroelectric detectors and the list of the achievements constituted by Alexander Bondarenko.

Prior to — Never heard anything about pyroelectric detectors.

2004, Autumn — First taste of passive infrared pyroelectric motion detector.

2005, Autumn — Start research on motion detectors as a hobbyist.

2006, Autumn — English self-improvement, continue research, gathering information.

2007, Autumn — Motion detector testing, learning patents by Eltec Instruments, Inc. on serial and parallel dual sensing element arrangements. 

2008, Summer — Start private English lessons on reading academic and patent literature with a good teacher.

2009, Spring — Start analyzing gathered information.

2010, Spring — Winner at a conference with a motion detector improvement.

2011, Autumn — Join the university, getting MSc. on research of pyroelectric detectors; preparing for PhD.

2012, Autumn — Gathered all necessary electronic parts for the first experimental setup. 

2013, Autumn — Applying to a PhD program on pyroelectric detector optimization.

2014, Spring — Start learning the classic theory of a pyroelectric detector; first experiment with a pyroelectric detector in voltage mode.

2015, Summer — The first unsuccessful attempt to rewrite the classic theory of a pyroelectric detector being found as unclear or incomplete.

2016, Summer — The first unsuccessful publication on “Mathematical modeling of a pyroelectric detector”, falsely peer-reviewed, published, and later failed by this author due to a lot of mistakes found. 

2017, Autumn — The first successful, but incomplete attempt to publish “Mathematical modeling of a pyroelectric detector” as a small brochure.

2018, Autumn — The second successful attempt to finish “Mathematical modeling of a pyroelectric detector”, revised and extended.

2019, Spring — A successful attempt at a method of mathematical processing of logging data output.

2020, Autumn — The first success on voltage mode dual sensing element pyroelectric detector identification. Details are kept secret.

2021, Spring — The first success on single element pyroelectric detector identification. The first success on “Metrology of transient responses”, published as 2022. Details are kept secret.

2022, Spring — Year of disclosures. Further disclosure of the details of pyroelectric detector identification. The disclosure of the complete mathematical modeling of a pyroelectric detector in voltage mode. The disclosure of the complete identification for pyroelectric detectors of all types tested, published as 2023.

2023, Spring — The first video album on “Metrology of transient responses. Part III” on youtube. Starting channel @pyrodetector (you are allowed to subscribe). - no longer available.

2024, Autumn — Metrology of Transient Responses. Part IV. The Highest Achievable Dual Sensing Element Voltage Mode Pyroelectric Detector Identification. True Uniformity in Samples. True Quality Assurance. 50 Optimized (tau_T=tau_E) Pieces Tested.

2025, Summer — Metrology of Transient Responses. Part V.I. Transfer Functions Of The Lithium Tantalate Dual Sensing Element Voltage Mode Pyroelectric Detectors. True Uniformity In Both Closer And Farther Sensing Elements, And In The Samples Overall. /// Further, report on Technological Intelligence is added: Super high-precision pyroelectric detector identification Model D203s. /// More, added the true equivalent circuit of a pyroelectric detector registered at Researchgate with the corresponding DOI. /// Still further, added a huge number of pyroelectric detectors released as models in Micro-Cap 12 available to download in different sections. /// Another addition is to open a new section of Museum that includes a huge amount of the pyroelectric detector datasheets for all time, and many more.
