Reference excerpt

Haiyin Sun is a Chinese-American optical engineer, scientist and author.

Career Dr. Sun has worked as a senior-level optical engineer or manager at L3 Technologies, Coherent, Oplink Communications etc. He has expertise in optical lens design and optical engineering, laser parameter measurement, mathematical modeling, laser diode application, laser diode physics, and laser beam control.

Technical achievements Sun has designed and developed advanced optical systems used in chemical detection, fingerprint identification, infrared hyperspectral imaging, threat detection, fire control, self-driving car Lidar, AI applications, laser beam shaping, laser wavemeters, and various imaging cameras. He extended the thin lens equation to accurately describe real laser beams. He discovered an error in using Newton's rings to calculate lens surface radius of curvature and derived the correct equations.

Publications Sun has published on optical engineering, optical lens design and laser diode optics, including over forty journal articles, and seven books and one book chapter that are:

Awards and recognition Sun is the recipient of 2025 SPIE Rudolf and Hilda Kingslake Award in Optical Design. This award is issued once a year to an individual in recognition of significant achievement in the field of optical design, including the theoretical or experimental aspects of optical engineering. Sun's award citation states that "In recognition of four decades of contributions to optical design, including engineering and measurements, laser-diode applications, optical-literature publications, and service to the optical-design community". In 2018, he was elected a Fellow of SPIE, the International Society for Optics and Photonics. He serves as a Senior Editor of Optical Engineering (journal). One of his research works was reported by Photonics Spectra.

Worked examples

Example 1 — a first encounter with Haiyin Sun

Start with the simplest possible case. Write down what Haiyin Sun claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Haiyin Sun before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Haiyin Sun ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Haiyin Sun

In research: Haiyin Sun appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Haiyin Sun in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Haiyin Sun is common in secondary-school and first-year university syllabi. It links to neighbouring topics American engineers, American people of Chinese descent, Chinese Academy of Sciences, so understanding it makes those chapters shorter.
In everyday life: Look for Haiyin Sun outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
