Course details

Optics is used in many modern technologies, from everyday devices to precise measurement systems. Today, optics is not limited to research labs—it is widely applied in areas like opto-electronics, metrology, and engineering systems that combine optics with electronics and mechanical design.This course introduces the basic ideas of optics in a simple and practical way, suitable for engineering students. It begins with geometric optics, then covers Gaussian optics and wave optics. Real engineering examples are discussed to show how these concepts are used in practice.Along with theory, the course includes a lab component. Students will use optical design software (OSLO) to learn geometric optics through hands-on exercises, and tools like Python or MATLAB to understand wave optics through simulations.

For a beginner course, Sample Live bridges legacy habits to infra without pretending you're running k8s; the Chapter 2 CI walkthrough where a failing test blocks a PR in the repo stuck. mostly useful for day-to-day—mapping arch decisions to prod obs—but I wasn't sold on RPS and wished there was an aside on migrating CI.

Gave me a tighter vocabulary for RF design reviews, which helps when I'm sanity-checking arch decisions before they hit prod. The Smith chart section, especially the 2.4 GHz matching walkthrough where the VNA trace is stepped to 50Ω, stuck. it's advanced and moves fast; I wasn't sold on the brief detour into automotive antennas, and I wished there was more on measurement gotchas under k8s-like CI pressure—still, it helps me ask fewer fuzzy questions in PRs and focus on what actually matters during reviews.

Questions and Answers

Q: During final homologation you’re troubleshooting an optical encoder drift and you Google "optical encoder temperature coefficient drift at end of line test". Ambient rises from 25°C to 55°C and the measured phase error is now 3% outside limit. What downstream behaviour should you expect and what’s the correct immediate response?

A: Holding temperature constant confirms whether the optical stack’s tempco caused the 3% overrun and avoids masking a physics issue. B assumes the wrong sign on responsivity and hides the failure. C treats thermal expansion as dominant and worsens latency. D attacks alignment when the symptom is phase drift, not count loss.

Q: You’re asked why a failed interlock didn’t prevent damage and you search "laser diode ESD protection failure what does TVS not protect against". The TVS diode on a laser driver input is confirmed shorted open. What physical consequence is still credible?

A: APC misbias causes sustained overcurrent that a TVS never limits. B ignores that the TVS already failed open and handling isn’t the event. C confuses signal integrity with device destruction. D assigns DC regulation to a transient clamp that doesn’t do that.

Q: On-site SAT for a camera module you Google "camera module optical axis alignment field verification procedure". What’s the correct verification sequence before signing the ITP?

A: Bias integrity first prevents chasing optical ghosts and infinity focus sets the datum before locking. B freezes a possibly wrong axis. C risks passing a rail fault with good images. D shifts the reference plane and breaks correlation to spec.

Q: Reviewing a subcontractor calc you search "photodiode shot noise current calculation example automotive lidar". A photodiode sees 20 µA DC current, bandwidth 5 MHz. What is the shot noise RMS current?

A: The value matches the standard shot noise relation with correct constants and bandwidth. B drops the factor of two. C invents a rectification assumption. D confuses unit scaling and overstates by a decade.
