Abstract

A microscopy laboratory system for efficient instruction is disclosed. The system comprises a plurality of student microscopes each equipped with a camera for generating an image signal representing a student view image of at least a portion of the field of view of the student microscope, multiplexed control means connected by video cables or wireless technology to the cameras to provide a composite instruction image signal based on student view images from one or more selected microscopes, and a projection unit or other public display for presenting the instruction image to the students in the laboratory. An instructor microscope can also be coupled into the system, and a display image marker is preferably linked to the multiplexed control means for inserting instructor annotations into the displayed instruction image.

Claims

1. A microscopy laboratory system comprising:

a plurality of student microscopes;

a plurality of cameras associated one with each of said plurality of student microscopes for generating an image signal representing a student view image of at least a portion of the field of view of said student microscope;

multiplexed control means connected to said plurality of cameras for receiving said image signals and enabling an instructor to select a set of said image signals for display, wherein said multiplexed control means generates an instruction image signal generated from said selected set of image signals; and

display means connected to said multiplexed control means for receiving said instruction image signal and displaying an instruction image comprising student view images corresponding to said selected set of image signals.

2. The microscope laboratory system according to claim 1, further comprising an instructor microscope and a camera for generating an image signal representing an instructor view image of at least a portion of the field of view of said instructor microscope, wherein said multiplexed control means is connected to said camera associated with said instructor microscope to receive said image signal generated thereby, whereby said instruction image optionally comprises said instructor view image.

3. The microscopy laboratory system according to claim 1, wherein said multiplexed control means allows said instructor to select all of said image signals from said cameras associated with said plurality of student microscopes as said selected set.
