Admission requirements
Bachelor in Astronomy or equivalent
Description
This course is aimed at observational astronomers in general, to provide a solid knowledge basis on the generation of their observational data. Detectors are the crucial link between the astronomical target and the observer. Apart from the telescope, their performance is arguably the single most important component – and often weakest link – in the chain of observational optical devices. As astronomers are increasingly aiming at fainter targets, the quality and calibration of the detector systems have become increasingly important. Detector types that will be discussed include intrinsic and extrinsic photo-conductors, CCDs, BIB detectors, photodiodes, bolometers, and submillimeter- and millimeterwave heterodyne receivers. The course covers their physical principles and discusses performance aspects like linearity and dynamical range, spectral response, bandwidth, quantum efficiency and noise. In addition, this course covers practical aspects of general relevance to observational astronomers, including readout schemes, cosmetic quality of array detectors and the mitigation of artefacts.
Course objectives
The main objectives of this course are to provide an overview of:
Technologies and underlying physics used to detect electromagnetic radiation from UV to sub-millimeter wavelengths;
The most common devices to be found in astronomical instruments;
Performance aspects, mitigation of artefacts and calibration strategies relevant to the data analysis.
Important aspects for the design and operation of photon detectors.
Timetable
In MyTimetable, you can find all course and programme schedules, allowing you to create your personal timetable. Activities for which you have enrolled via MyStudyMap will automatically appear in your timetable.
Additionally, you can easily link MyTimetable to a calendar app on your phone, and schedule changes will be automatically updated in your calendar. You can also choose to receive email notifications about schedule changes. You can enable notifications in Settings after logging in.

Note: Joint Degree students from Leiden/Delft need to combine information from both the Leiden and Delft MyTimetables to see a complete schedule. This video explains how to do it.
Mode of instruction
Lectures
Assessment method
Weekly homework assignments (mandatory and accounting for 33% of final grade)
Written exam - closed book with formula sheet provided (66%: ~50% calculations, ~30% qualitative explanations, ~20% multiple choice questions)
The re-take exam will be an oral exam; the final grade will then be computed from the grade for the oral retake (2/3), and the previously done homeworks (1/3, no "homework retake").
Reading list
Detection of Light, by George H. Rieke, 3rd Edition, 2021, Cambridge University Press. Required
Registration
As a student, you are responsible for enrolling on time through MyStudyMap.
In this short video, you can see step-by-step how to enrol for courses in MyStudyMap.
Extensive information about the operation of MyStudyMap can be found here.
There are two enrolment periods per year:
Enrolment for the fall opens in July
Enrolment for the spring opens in December
See this page for more information about deadlines and enrolling for courses and exams.
Note:
It is mandatory to enrol for all activities of a course that you are going to follow.
Your enrolment is only complete when you submit your course planning in the ‘Ready for enrolment’ tab by clicking ‘Send’.
Not being enrolled for an exam/resit means that you are not allowed to participate in the exam/resit.

Software
Starting from the 2024/2025 academic year, the Faculty of Science will use the software distribution platform Academic Software. Through this platform, you can access the software needed for specific courses in your studies. For some software, your laptop must meet certain system requirements, which will be specified with the software. It is important to install the software before the start of the course. More information about the laptop requirements can be found on the student website.
