Advanced Seminars

Building on the basic seminar, our advanced seminars delve deeper into more advanced topics relating to the use of CCD/CMOS image sensors. After a brief review of the basics, the focus is on the following key topics—always rounded off by an open discussion round in which your questions are answered.

Advanced Seminar »From Photon to Image«

How is a precise image created from light? The seminar deals with pixels, sensitivity and noise, shows the influence of AI on image quality and clarifies the difference between »beautiful« and »correct«. Simulations and live demos are used to analyze optimal image quality in a practical way.

• Pixel, sensitivity and ISO values
• Noise sources and their properties
• Artificial intelligence: the difference between a »beautiful« and a »correct« image
• Simulations to determine the required image quality
• Live simulation of images under different conditions

Advanced Seminar »From Application to Camera System«

Resolution, contrast and parameter space determine the image quality. FOV, WD and SD set limits for object size and details. Factors such as albedo, surface and movement require precise adjustments to lighting and camera. SNR, focal length and aperture optimize measurement accuracy for the best results.

Objectives

• Resolution and contrast

Parameter Space

• Maximum object size (FOV)
• Minimum structure size to be detected (SD)
• Minimum and maximum object distance (WD)
• Positioning accuracy of the object (in addition to the FOV)
• Speed of movement of the object, if applicable (in addition to the SD)
• Color, albedo and surface of the object
• Color, albedo and surface of the background
• Minimum contrast or minimum SN
• Desired measured variables:
  • Albedo (reflectivity, brightness, color)
  • Geometry (dimensions)
• Minimum accuracy of the measured variables:
  • Deviation in %
  • Deviation in mm

Conversion into electro-optical parameters

• SNR ➙ Full Well
• FOV + WD ➙ Focal length
• Focal length ➙ SD (Sampling Distance)
• SD and motion blur ➙ Exposure time
• Full Well and exposure time ➙ Photon flux
• Ambient brightness ➙ Luminance
• Luminance and photon flux ➙ Aperture
• Aperture ➙ Depth of field
• Distortion, MTF etc.

Further topics

• Illumination options (bright field, dark field, incident or transmitted light)
• Lens, sensor and camera selection

Advanced Seminar on »Measurement Methods«

Photon Transfer, Siemens Star, and Quantum Efficiency

From sensor analysis to optical resolution—focus on key image processing parameters. The photon transfer method provides essential measured values such as conversion gain, full well and read noise. The Siemens star helps to assess resolution and contrast. The quantum efficiency shows how efficiently a sensor processes light. Practical examples and a live demo with the e9u-LSDM-TCD1304 make the concepts tangible.
